A higher-order topological twist on cold-atom SO(5) Dirac fields
A. Bermudez, D. González-Cuadra, S. Hands
Ultracold Fermi gases of spin-3/2 atoms provide a clean platform to realise SO(5) models of 4-Fermi interactions in the laboratory. By confining the atoms in a two-dimensional Rama…
Correlated Chern insulators in two-dimensional Raman lattices: a cold-atom regularization of strongly-coupled four-Fermi field theories
L. Ziegler, E. Tirrito, M. Lewenstein +2
We show that ultra-cold atoms with synthetic spin-orbit coupling in Raman lattices can be used as versatile quantum simulators to explore the connections between correlated Chern i…
Dirac-Weyl fermions with arbitrary spin in two-dimensional optical superlattices
Z. Lan, N. Goldman, A. Bermudez +2
Dirac-Weyl fermions are massless relativistic particles with a well-defined helicity which arise in the context of high-energy physics. Here we propose a quantum simulation of thes…
Wilson Fermions and Axion Electrodynamics in Optical Lattices
A. Bermudez, L. Mazza, M. Rizzi +3
The formulation of massless relativistic fermions in lattice gauge theories is hampered by the fundamental problem of species doubling, namely, the rise of spurious fermions modify…
