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…

Three-body constrained bosons in double-well optical lattice

Suman Mondal, Sebastian Greschner, Tapan Mishra

We analyse the ground-state properties of three-body constrained bosons in a one dimensional optical lattice with staggered hoppings analogous to the double well optical lattice. B…

Hidden order and symmetry protected topological states in quantum link ladders

Lorenzo Cardarelli, Sebastian Greschner, Luis Santos

We show that whereas spin-1/2 one-dimensional U(1) quantum-link models (QLMs) are topologically trivial, when implemented in ladder-like lattices these models may present an intrig…
