Deconfining disordered phase in two-dimensional quantum link models
Lorenzo Cardarelli, Sebastian Greschner, Luis Santos
We explore the ground-state physics of two-dimensional spin- quantum link models, one of the simplest non-trivial lattice gauge theories with fermionic matter within ex…
Topological charge pumping of bound bosonic pairs
Sebastian Greschner, Suman Mondal, Tapan Mishra
Experiments with bosonic atoms in optical superlattices allow for the interesting possibility to study the adiabatic quantized pumping of bosonic atoms in the presence of interacti…
Vanishing Hall Response of Charged Fermions in a Transverse Magnetic Field
Michele Filippone, Charles-Edouard Bardyn, Sebastian Greschner +1
We study the Hall response of quasi-two-dimensional lattice systems of charged fermions under a weak transverse magnetic field, in the ballistic coherent limit. We identify a setup…
Interacting bosons in generalized zig-zag and railroad-trestle models
Sebastian Greschner, Tapan Mishra
We theoretically study the ground-state phase diagram of strongly interacting bosons on a generalized zig-zag ladder model, the rail-road trestle (RRT) model. By means of analytica…
