Quasiparticles in quantum spin chains with long-range interactions
Laurens Vanderstraeten, Maarten Van Damme, Hans Peter Büchler +1
We study quasiparticle excitations for quantum spin chains with long-range interactions using variational matrix product state techniques. It is confirmed that the local quasiparti…
Full Counting Statistics for Interacting Fermions with Determinantal Quantum Monte Carlo Simulations
Stephan Humeniuk, Hans Peter Büchler
We present a method for computing the full probability distribution function of quadratic observables for the Fermi-Hubbard model within the framework of determinantal quantum Mont…
Topological states in a microscopic model of interacting fermions
Nicolai Lang, Hans Peter Büchler
We present a microscopic model of interacting fermions where the ground state degeneracy is topologically protected. The model is based on a double-wire setup with local interactio…
Vortex Lattice Locking in Rotating Two-Component Bose-Einstein Condensates
Ryan Barnett, Gil Refael, Mason A. Porter +1
The vortex density of a rotating superfluid, divided by its particle mass, dictates the superfluid's angular velocity through the Feynman relation. To find how the Feynman relation…
Atomic quantum simulator for lattice gauge theories and ring exchange models
H. P. Büchler, M. Hermele, S. D. Huber +2
We present the design of a ring exchange interaction in cold atomic gases subjected to an optical lattice using well understood tools for manipulating and controlling such gases. T…
