Quantum electronics has significantly evolved over the last decades. Where initially the clear
focus was on light–matter interactions, nowadays approaches based on the electron's wave …

Topological insulators (TIs) are a new class of materials that resemble ordinary band
insulators in terms of a bulk band gap but exhibit protected metallic states on their …

We report on the theoretical investigation of the topological properties of a periodically
quenched one-dimensional dimerized lattice where a piecewise constant Hamiltonian …

After extensive investigation of the Floquet second-order topological insulator (FSOTI) in two
dimensions, here we propose two driving schemes to systematically engineer the hierarchy …

The presence of random disorder in a metallic system accounts for the localization of
extended states in general. On the contrary, the presence of disorder can induce topological …

Periodically driven systems offer a perfect breeding ground for out-of-equilibrium
engineering of topological boundary states at zero energy (0 mode), as well as finite energy …

The impact of weak disorder and its spatial correlation on the topology of a Floquet system is
not well understood so far. In this study, we investigate a model closely related to a two …

We propose and show that application of light leads to an intriguing platform for controlling
exceptional points in non-Hermitian topological systems. We demonstrate our proposal …

Anderson localization in two-dimensional topological insulators takes place via the so-called
levitation and pair annihilation process. As disorder is increased, extended bulk states …

We show that an interacting two-spin model subjected to two circularly polarized drives
enables a feasible realization of a correlated topological phase in synthetic dimensions. The …
