Topological physics opens up a plethora of exciting phenomena allowing to engineer
disorder-robust unidirectional flows of light. Recent advances in topological protection of …

The bulk–boundary correspondence, a fundamental principle relating the topological
invariants of the bulk to the presence of edge states, is modified in periodically driven …

The latest advances in the field of photonics have enabled the simulation of an increasing
number of quantum models in photonic systems, turning them into an important tool for …

Bound states of two interacting particles moving on a lattice can exhibit remarkable features
that are not captured by the underlying single-particle picture. Inspired by this phenomenon …

Arrays of highly excited Rydberg atoms can be used as powerful quantum simulation
platforms. Here, we introduce an approach that makes it possible to implement fully …

We study topological features of interacting spin-1 2 particles in one-dimensional state-
dependent optical lattices. Due to the cotranslational symmetry, we introduce the center-of …

In flat-band systems, destructive interference leads to the localization of noninteracting
particles and forbids their motion through the lattice. However, in the presence of …

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 …

Beyond the well-known topological band theory for single-particle systems, it is a great
challenge to characterize the topological nature of interacting multiparticle quantum …

We consider quantum condensed matter systems without particle-number conservation.
Since the particle number is not a good quantum number, states belonging to different …
