Locality Preserving Unitaries Beyond QCA
Carolyn Zhang - Harvard University
We study a locality preserving unitary (LPU) in three spatial dimensions that “pumps” a Chern insulator to the physical boundary. In the single-particle setting, the LPU cannot be generated by any local Hamiltonian. However, it is not a quantum cellular automaton (QCA) because it transforms strictly… -
Probing Conformal Boundary/Defect and Spin Liquid through “Snapshots”
Cenke Xu
Snapshots are the standard data produced in many quantum simulators. In this talk we demonstrate that they encode far more information than conventional correlation functions. I’ll show how snapshot data can probe conformal boundaries and defects in quantum many-body systems. In particular, from… -

Instanton and Chern-Simons in Lattice Yang-Mills Theory from Higher Category Theory
Jing-Yuan Chen - Tsinghua IAS
Putting continuum QFT (not just TQFT) onto the lattice is important for both fundamental understandings and numerical practices. The traditional way to do so, based on simple intuitions, however, does not admit natural definitions for general topological configurations of continuous-valued fields--… -

Superconductivity, with Anyons
Hart Goldman - University of Minnesota
I will discuss the phenomenology of superconductors hosting both order parameter vortices and fractionally charged anyon excitations. I will demonstrate that in such systems superconductivity and topological order are intertwined under applied magnetic fields, leading to surprising observable… -

Bound on the dynamical exponent of frustration-free Hamiltonians and Markov processes
Tomohiro Soejima - Harvard University
Exactly solvable models have tremendously helped our understanding of condensed matter systems. A notable number of them are "frustration-free" in the sense that all local terms of the Hamiltonian can be minimized simultaneously. It has been particularly successful at describing the physics of… -
