Speaker: Roman Geiko (UCLA) Title: When does a three-dimensions Chern-Simons theory have a time reversal symmetry? In this talk, I will discuss the time reversal invariance of (spin-) Chern-Simons theory in 3 dimensions at both classical and quantum levels. I will show how to obtain a complete classification of Abelian anyons with the time reversal […]
Quantum Matter Seminar Speaker: Aleksey Cherman (UMN) Title: Exact lattice chiral symmetry in 2d gauge theory Abstract: Preserving the symmetries of massless fermions is a well-known challenge in lattice field theory. I'll discuss symmetry-preserving lattice regularizations of 2d QED with one and two flavors of Dirac fermions, as well as the `3450' chiral gauge theory. […]
Quantum Matter in Mathematics and Physics Seminar Speaker: Daniel Harlow (MIT) Title: Gauging spacetime inversions Abstract: Spacetime inversion symmetries such as parity and time reversal play a central role in physics, but they are usually treated as global symmetries. In quantum gravity there are no global symmetries, so any spacetime inversion symmetries must be gauge […]
Quantum Matter in Mathematics and Physics Seminar Speaker: Anurag Anshu (Harvard) Title: Quantum Circuits to local Hamiltonian: role in quantum complexity and new constructions Abstract: At the heart of the theory of NP completeness lies a mapping from classical circuits to constraint satisfaction problems (classical local Hamiltonians). The quantum analogue of this is the remarkable history […]
Quantum Matter in Mathematics and Physics Seminar Speaker: Yuta Hamada (KEK, Tsukuba) Title: Flavor hierarchy from smooth confinement & Towards a complete classification of 6d supergravities Abstract: The talk consists of two independent parts. In the first part, I will talk about a new model to explain the Standard Model flavor hierarchy. Our model is […]
Quantum Matter in Mathematics and Physics Seminar Speaker: Soonwon Choi (MIT) Title: Quantum Algorithms to Recognize Phases of Matter and Exactly Solvable 2D Models with Anomalous Entanglement Entropy Abstract: In this talk, I will report my two recent results at the intersection of quantum information and strongly interacting phases of matters. In the first half […]
Quantum Matter in Mathematics and Physics Seminar Speaker: Sen Hu (Shanghai Institute for Mathematics and Interdisciplinary Study) Title: Quantum Algebra of Chern-Simons Matrix Model and Large N Limit Abstract: In this talk we discuss the algebra of quantum observables of the Chern-Simons matrix model which was originally proposed by Susskind and Polychronakos to describe electrons […]
Quantum Matter in Mathematics and Physics Seminar Speaker: Susanne Yelin (Harvard) Title: Programmable Simulations of Molecules and Materials with present-day Reconfigurable Quantum Processors Abstract: Simulations of quantum chemistry and quantum materials are believed to be among the most important potential applications of quantum information processors, but realizing practical quantum advantage for such problems is challenging. […]
Quantum Matter in Mathematics and Physics Seminar Speaker: Motoo Suzuki (Harvard) Title: Spontaneously Broken (-1)-form symmetries Abstract: Spontaneous breaking of symmetries leads to universal phenomena. We extend this notion to (−1)-form U(1) symmetries. The spontaneous breaking is diagnosed by a dependence of the vacuum energy on a constant background field θ, which can be probed […]
Quantum Matter in Mathematics and Physics Seminar Speaker: Semeon Valgushev (Iowa State University) Title: A model for studying the sign problem on quantum computers: Z(3) gauge theory with three fermion flavors in 1+1 dimensions Abstract: Many properties of quantum field theories can be understood with the help of classical numerical methods. Yet there are several […]
Quantum Matter in Mathematics and Physics Seminar Speaker: Shu-Heng Shao (SUNY Stony Brook) Title: Cluster state as a noninvertible SPT phase Abstract: We will point out a non-invertible symmetry of the ordinary 1+1d Z2xZ2 cluster Hamiltonian. Therefore, the cluster state can be viewed as a non-invertible SPT phase under this fusion category symmetry, which is […]
Quantum Matter in Mathematics and Physics Seminar Speaker: Diego Delmastro (Simons Center for Geometry and Physics) Title: Monopoles, scattering, generalized symmetries Abstract: Gauge theory is a very mature subject by now. Surprisingly, some of its symmetries have only been properly understood in the last couple of years. Specifically, such theories typically have a very rich set […]
