Adiabatic preparation of a number-conserving atomic Majorana phase
Benjamin Michen, Tim Pokart, Jan Carl Budich
We construct a protocol to adiabatically prepare the ground state of a widely discussed number-conserving model Hamiltonian for ultracold atoms in optical lattices that supports Ma…

Exceptional Luttinger Liquids from sublattice dependent interaction
J. Schwardt, B. Michen, C. Lehmann +1
We demonstrate how Exceptional Points (EPs) naturally occur in the Luttinger Liquid (LL) theory describing the low-energy excitations of a microscopic lattice model with sublattice…
