What is String Theory? Weaving Perspectives Together
08 Jan 2024 - 19 Apr 2024 • KITP, Santa Barbara, United States
Organizer:
Kavli Institute for Theoretical Physics (KITP)
Abstract:
While it is widely acknowledged that string theory provides a framework for addressing quantum gravitational (and even quantum field theoretic) questions, the precise nature of its organizational principle remains obscure. Nearly three decades ago, when the question “What is string theory?” was asked, the perturbative string worldsheet viewpoint played the starring role. Since then, the discovery of D-branes, string dualities, and the holographic AdS/CFT correspondence has had spacetime dynamics taking center-stage. Much insight has been gleaned from these developments. We now have, for example, a much broader class of string backgrounds with better control over compactifications; strong constraints on the low energy effective field theories; a plethora of gauge-string dualities as well as applications of holographic techniques to a wide class of physical problems; and new angles on semiclassical gravitational physics from a fruitful interplay with quantum information in holography. Together with an influx of new tools and techniques, we have a very rich set of perspectives that illuminate the subject we continue to call string theory. While all these developments are interesting in and of themselves, it is an opportune moment to attempt to synthesize these, often disparate, strands and arrive at a deeper answer to the question in the title.

Anticipating the Rising Tide of Tidal Disruption Events: Theory and Observations
22 Apr 2024 - 25 Apr 2024 • Santa Barbara, United States
Organizer:
UC Santa Barbara, Kavli Institute for Theoretical Physics (KITP)
Abstract:
Tidal disruption events (TDEs), which occur when a star is destroyed by the immense tidal field of a supermassive black hole, fuel luminous accretion flares that provide unique insight into the properties of galactic nuclei and their central black holes. The detection rate of these events has accelerated in recent years thanks to advances in wide-field survey capabilities across the electromagnetic spectrum. Nonetheless, there remain theoretical uncertainties in the modeling of TDEs that obfuscate understanding in the face of observations, and our ability to use TDEs as a collective Rosetta Stone for deciphering black hole demographics across cosmic time remains elusive. To bridge theory and observation and to start to tap the wealth of understanding contained within TDE observations, this conference aims to unite the diverse field of astronomers working on TDEs and the related fields of variable Active Galactic Nuclei (AGN) and X-ray binaries. This conference will highlight the recent advances that have been made in understanding TDEs, make connections to related astrophysical phenomena, and elucidate the most outstanding questions in TDE theory and observation.

Teachers' Conference — Supermassive Black Holes and their Destructive Tidal Forces
24 Apr 2024 - 27 Apr 2024 • Santa Barbara, United States
Organizer:
UC Santa Barbara, Kavli Institute for Theoretical Physics
Abstract:
Most galaxies, including our own Milky Way, harbor supermassive black holes at their centers. When a star wanders too close to one of these black holes, it can be torn apart by the black hole's incredible tidal gravitational field; this stellar destruction by tides transforms the spherical star into a “spaghettified” stream of stellar debris. In a matter of months, a fraction of this debris stream heats up and falls into the black hole, producing a flare of light. Studying this process, called a tidal disruption event (TDE), tests our understanding of physics in extreme conditions and illuminates the environment immediately surrounding the black hole, which is otherwise invisible. This conference will cover the physics of supermassive black holes and the effects of their disruptive tidal forces, incorporating recent observational and theoretical advances in the rapidly-developing study of TDEs. We will also discuss activities that participating teachers can use to illustrate some of these concepts in the classroom.

Cosmic Signals of Dark Matter Physics: New Synergies
03 Jun 2024 - 06 Jun 2024 • Santa Barbara, United States
Organizer:
UC Santa Barbara, Kavli Institute for Theoretical Physics (KITP)
Abstract:
Observables spanning a wide range of cosmic epochs and length-scales independently testify to the existence of dark matter. Although little is known about the microphysical nature of dark matter, its mere existence points to physics beyond the Standard Model. New developments in theory, cosmological simulations, and observational capabilities in the era of large surveys have opened up a vast landscape for dark matter discovery, which includes models that can only be tested by astrophysical and cosmological probes.

Multi-messenger Transients — Multi-messenger Transients from Binary Mergers & Stellar Explosions
04 Aug 2024 - 25 Aug 2024 • Aspen, Colorado, United States
Abstract:
The first joint gravitational wave and electromagnetic detection of the binary neutron star GW170817 marked the dawn of the multi-messenger era with GWs. This watershed event opened a new window to study phenomena such as heavy element nucleosynthesis, black hole formation, the Universe's expansion rate, the equation of state of dense matter, and the intricate dynamics of relativistic jets. These profound inquiries have reignited interest in investigating similar physical processes at play in black hole-neutron star mergers and core-collapse supernovae. This endeavor necessitates the development of predictive models in anticipation of forthcoming observations in 2024 by LIGO-Virgo-KAGRA, Rubin Observatory, and future observation campaigns, that will transform the field of high-energy astrophysics transients. The primary goal of this workshop is to bring together physicists with diverse backgrounds in both theoretical and observational expertise within the domains of electromagnetic, gravitational wave, and particle emissions. Collectively, they will engage in collaborative efforts to identify and investigate pathways for tackling the pivotal scientific questions at the core of this rapidly evolving field.

Rise_Time: Explosive Astrophysics in the era of High-Cadence Astronomy
07 Aug 2024 - 09 Aug 2024 • West Lafayette, Indiana, United States
Organizer:
Purdue University, Department of Physics and Astronomy
Abstract:
Time-domain astronomy is rapidly evolving, and astronomers have become increasingly good at catching fast transients on very short timescales. Additionally, both theorists and observers working on astrophysical transients have a habit of expanding their science across several subfields, resulting in a highly interconnected community. This motivates a continuous opening of new lines of communication between transient scientists, developed in a highly active and engaging conference setting. Rise_Time is a conference for transient astrophysicists of all kinds; theorists, observers, and numericists; experts on gravitational waves, radio, optical, IR, UV, X-Rays, gamma rays, cosmic rays, neturinos, and any other observing technologies we didn't think to mention. We aim to generate a highly diverse, inclusive, and interactive environment, with plenty of time and energy allocated for questions and interactive discussions. Attendees are encouraged to be participants rather than spectators.

Cosmic Dawn Revealed by JWST: The Physics of the First Stars, Galaxies, and Black Holes
26 Aug 2024 - 29 Aug 2024 • UC Santa Barbara, United States
Organizer:
UC Santa Barbara, Kavli Institute for Theoretical Physics (KITP)
Abstract:
The exploration of cosmic dawn is currently in an exceptionally exciting phase, and we expect the immediate future to be even more exciting with a new set of discoveries delivered by JWST. The observations of first stars, galaxies, and black holes with JWST and other facilities provide a unique “stress test” for a new generation of theoretical models of galaxy formation. The aim of the conference is to bring together theorists and observers to discuss the following key questions: What can we learn from JWST data on the nature of the first stars and black hole seeds? What is the nature of the stellar populations inhabiting the first galaxies? What are the star formation and chemical enrichment histories of early galaxies? Do we understand the key physical processes that shape the evolution of these early galaxies and their black holes? How can we connect the pictures derived from near-field and deep field observations?

Generalized Symmetries: High-Energy, Condensed Matter and Mathematics
07 Apr 2025 - 10 Apr 2025 • Santa Barbara, United States
Organizer:
UC Santa Barbara, Kavli Institute for Theoretical Physics
Abstract:
Over the past ten years tremendous progress has been achieved in quantum field theory thanks to the realization that symmetries can be interpreted in terms of the action of topological defects on the space of operators. This gives a generalization of the notion of symmetries, explicitly realized in many instances exploiting Lagrangian field theory techniques, uncovering a rich and unexpected landscape of physical effects in condensed matter, high energy physics, and quantum gravity. This conference will bring together the major experts in the subject, and strives to be an opportunity for participants to quickly get up to speed with the most recent advances and open problems in the field.

Planets on the Edge
05 May 2025 - 08 May 2025 • Santa Barbara, United States
Organizer:
UC Santa Barbara, Kavli Institute for Theoretical Physics
Abstract:
The Kepler and TESS missions, as well as ground-based telescopes, have discovered thousands of planets on short-period orbits around other stars, including many that are Earth-size and likely to be rocky. These objects have no direct counterparts in the Solar System, and the corresponding inner regions within the protoplanetary disks that spawned them are challenging to study. This conference will confront this challenge and advance our understanding of the nature, formation and evolution of Earth-sized planets in inner protoplanetary disks by bringing together diverse experts in exoplanet demographics, protoplanetary disks, models of disks and planet formation, and meteoritics to address four key questions: (1) what is the nature of close-in rocky planets and their atmospheres? (2) do they form in situ or migrate inwards after forming further out? (3) what are the governing parameters that could vary between star systems? and (4) why are there no analogous planets around the Sun? The conference will complement and energize the associated KITP Program by including a broader range of participants and highlighting recent observational results. The goals of the conference are to synthesize current knowledge of the properties of planets and inner disks, describe the state of the art in models of planet formation and evolution, catalyze interactions between different fields, and chart a path forward for advances in observations, theory, and computational modeling.
