Atomtronics deals with matter-wave circuits of ultracold atoms manipulated through
magnetic or laser-generated guides with different shapes and intensities. In this way, new …

Coupled-wire constructions use bosonization to analytically tackle the strong interactions
underlying fractional topological states of matter. We give an introduction to this technique …

Quantum simulators are attracting great interest because they promise insight into the
behavior of quantum many-body systems that are prohibitive for classical simulations. The …

Experimental realizations of topologically ordered states of matter, such as fractional
quantum Hall states, with cold atoms are now within reach. In particular, optical lattices …

Flux ladders constitute the minimal setup enabling a systematic understanding of the rich
physics of interacting particles subjected simultaneously to strong magnetic fields and a …

Symmetry-resolved entanglement is a useful tool for characterizing symmetry-protected
topological states. In two dimensions, their entanglement spectra are described by …

We unveil an interesting connection of Lorentz-violating quantum field theories, studied in
the context of the standard model extension, and Hubbard-type models of topological …

The realization of interacting topological states of matter such as fractional Chern insulators
(FCIs) in cold atom systems has recently come within experimental reach due to the …

We consider the properties of T= 0 quantum phases of matter—especially superconducting
and analogous spin-liquid phases—on infinite cylinders of width L⊥ and analyze the ways …

In strictly one-dimensional systems, repulsive interactions tend to reduce particle mobility on
a lattice. Therefore, the Drude weight, controlling the divergence at zero-frequency of optical …
