CTQM Theory Colloquium

Abstract: Magnetism is the posterchild of how the interplay between electron-electron interactions and quantum physics promotes novel macroscopic phenomena. Historically, the evolution of our understanding of magnetism has been related to the discovery of new paradigms in condensed-matter physics, as exemplified by the connections between antiferromagnetism and Mott insulators, spin glasses and non-ergodic states, and spin liquids and fractionalized excitations.

Abstract: We will discuss a dimensional hierarchy of the following over lattice systems of qudits.

Abstract:  There has been quite a bit of recent progress on the quantum mechanics of black hol

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.

Abstract:   In recent years, superconducting qubits have emerged as a leading platform for quantum simulation, particul

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

Abstract: The modern understanding of quantum materials traces back to Felix Bloch, who first applied quantum mechanics to crystalline lat

Abstract: Can a classical system of interacting particles evolving under local rules have multiple steady states that are stable to
