Topological phases of unitaries in low dimensions

-
Abstract: We will discuss a dimensional hierarchy of the following over lattice systems of qudits.
CTQM Theory Colloquium
Quantum mechanics and observers for quantum gravity in a closed universe
When
-
Abstract: There has been quite a bit of recent progress on the quantum mechanics of black hol
Digital quantum magnetism at the frontier of classical simulations
When
-
Abstract: The utility of near-term quantum computers for simulating realistic quantum systems hinges on the stability of digital quantum matter--realized when discrete quantum gates approximate continuous time evolution--and whether it can be maintained at system sizes and time scales inaccessible to classical simulations.
The gravitational path integral from an observer's point of view
When
-
Abstract: One of the fundamental problems in quantum gravity is to describe the experience of a gravitating observer in generic spacetime
Novel quantum dynamics with superconducting qubits
When
-
Abstract: In recent years, superconducting qubits have emerged as a leading platform for quantum simulation, particul
Defeating the Chiral Doubling Theorem: Three paths to new phenomena
When

Abstract: Over forty years ago, Nielsen and Ninomiya proved that chiral modes cannot exist in discrete systems without a m
Hyperbolic quantum matter
When

Abstract: The modern understanding of quantum materials traces back to Felix Bloch, who first applied quantum mechanics to crystalline lat
A local automaton for the 2D toric code
When

Abstract: Can a classical system of interacting particles evolving under local rules have multiple steady states that are stable to
Universal Bounds in interface conformal field theories
When
-
Abstract: Critical phenomena in the presence of interfaces provide a
much richer arena than their more studied cousin of boundary critical
phenomena. In this talk, I'll review certain observables that are new
and unique in interface conformal field theory and then demonstrate some
novel bounds we can derive on these quantities using techniques from
holography and quantum information.
The Physics Frontiers Centers (PFC) program supports university-based centers and institutes where the collective efforts of a larger group of individuals can enable transformational advances in the most promising research areas. The program is designed to foster major breakthroughs at the intellectual frontiers of physics by providing needed resources such as combinations of talents, skills, disciplines, and/or specialized infrastructure, not usually available to individual investigators or small groups, in an environment in which the collective efforts of the larger group can be shown to be seminal to promoting significant progress in the science and the education of students. PFCs also include creative, substantive activities aimed at enhancing education, broadening participation of traditionally underrepresented groups, and outreach to the scientific community and general public.
