Exact fermionic dual of the Bose-Hubbard model
Lei Su, Ivar Martin, Aashish A. Clerk
Recent developments have established exact bosonization and fermionization with a symmetry as dualities through gauging. In this work, we apply fermionic gauging, wh…
Global regularity for 2D gravity water waves with two retreating point vortices
Lei Su, Qingtang Su, Siwei Wang
We prove global well-posedness for the two-dimensional infinite-depth gravity water wave system coupled to a pair of point vortices of opposite strengths. The vortex dipole is init…
Bosonization and Kramers-Wannier dualities in general dimensions
Lei Su, Ivar Martin
It is well known that the noninteracting Majorana chain is dual to the one-dimensional transverse-field Ising model, either through the Jordan-Wigner transformation or by gauging f…
Quantum Mpemba effect without global symmetries
Tanmay Bhore, Lei Su, Ivar Martin +2
The Mpemba effect, where a system initially farther from equilibrium relaxes faster than one closer to equilibrium, has been extensively studied in classical systems and recently e…
Global anomalies of Green's function zeros
Lei Su, Ivar Martin
We study global anomalies of nonlocal effective theories proposed to describe symmetry-preserving Luttinger surfaces, i.e., the momentum-space manifolds of Green's function zeros (…
