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: 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 […]

Quantum Matter in Mathematics and Physics Seminar Speaker: Sungwoo Hong, Korea Advanced Institute of Science and Technology (KAIST) Title: Non-Invertible Peccei-Quinn Symmetry and the Massless Quark Solution to the Strong CP Problem Abstract: In this talk, I will discuss a new solution to the strong CP problem, one of the most important and challenging problems, […]

Quantum Matter in Mathematics and Physics Seminar Speaker: Henry Cohn (MIT and Microsoft) Title: Discrete geometry and the modular bootstrap Abstract: In this talk, I'll discuss the remarkable connections between the modular bootstrap and sphere packing or ground state problems discovered by Hartman, Mazáč, and Rastelli in 2019, with a focus on opportunities for further […]

Quantum Matter in Mathematics and Physics Seminar Speaker: Chetan Nayak, Microsoft and UCSB Title: Fusion Rule Measurement in a Topological Qubit

Quantum Matter in Mathematics and Physics Seminar Speaker: Jesse Thaler, MIT Title: What Observables are Safe to Calculate? Abstract: In collider physics, perturbative quantum field theory is the workhorse framework for computing theoretical predictions to compare to experimental measurements. An observable is called "safe" if its cross section can be predicted order-by-order in perturbation theory […]
