The combination of topology and quantum criticality can give rise to an exotic mix of
counterintuitive effects. Here, we show that unexpected topological properties take place in …

Thouless pumping represents a powerful concept to probe quantized topological invariants
in quantum systems. We explore this mechanism in a generalized Rice-Mele Fermi-Hubbard …

We investigate the topological properties of the bond order wave phase arising in the
extended Fermi-Hubbard model. In particular, we uncover a topological sector, which …

In this work, we investigate a two-dimensional system of ultracold bosonic atoms inside an
optical cavity, and show how photon-mediated interactions give rise to a plaquette-ordered …

We study the topological properties of hardcore bosons on a two-leg ladder consisting of two
Su-Schrieffer-Heeger chains that are coupled via hopping and interaction. We chart out the …

Higher-order topological crystalline phases in low-dimensional interacting quantum systems
represent a challenging and largely unexplored research topic. Here, we derive a …

We investigate the interacting, one-dimensional Rice-Mele model, a prototypical fermionic
model of topological properties. To set the stage, we first compute the single-particle spectral …

We recapitulate recent developments of the functional renormalization group (FRG)
approach to the steady state of systems out of thermal equilibrium. In particular, we discuss …

We propose a scheme to achieve the periodically modulated Su-Schrieffer-Heeger model
based on a one-dimensional optomechanical lattice. We show the energy-eigenvalue …

We investigate a second-order topological quantum transition of a modified Kane-Mele
model driven by an electron-phonon interaction. The results show that the system …
