Quantum Simulation of Hyperbolic Space with Circuit Quantum Electrodynamics: From Graphs to Geometry
Igor Boettcher, Przemyslaw Bienias, Ron Belyansky +2
We show how quantum many-body systems on hyperbolic lattices with nearest-neighbor hopping and local interactions can be mapped onto quantum field theories in continuous negatively…

Interplay of topology and electron-electron interactions in Rarita-Schwinger-Weyl semimetals
Igor Boettcher
We study for the first time the effects of strong short-range electron-electron interactions in generic Rarita--Schwinger--Weyl semimetals hosting spin-3/2 electrons with linear di…

Ground state of the three-dimensional BCS d-wave superconductor
Igor F. Herbut, Igor Boettcher, Subrata Mandal
We determine the mean-field ground state of the three-dimensional rotationally symmetric d-wave () superconductor at weak coupling. It is a non-inert state, invariant under…
