Topological semimetals (TSMs) are characterized by bulk band crossings in their electronic
structures, which are expected to give rise to gapless electronic excitations and topological …

Light–matter interaction in 2D and topological materials provides a fascinating control knob
for inducing emergent, non-equilibrium properties and achieving new functionalities in the …

In topological semimetals, the valance band and conduction band meet at zero-dimensional
nodal points or one-dimensional nodal rings, which are protected by band topology and …

The realization of Dirac and Weyl physics in solids has made topological materials one of
the main focuses of condensed matter physics. Recently, the topic of topological nodal line …

Topological nodal-line semimetals are characterized by one-dimensional lines of band
crossing in the Brillouin zone. In contrast to nodal points, nodal lines can be in topologically …

Periodically driven (Floquet) systems have been under active theoretical and experimental
investigations. This paper aims at a systematic study in the following aspects of Floquet …

Controlled excitation of materials can transiently induce changed or novel properties with
many fundamental and technological implications. Especially, the concept of Floquet …

We review recent work on low-frequency Floquet engineering and its application to quantum
materials driven by light, focusing on van der Waals systems hosting Moiré superlattices …

Floquet engineering, the concept of tailoring a system by a periodic drive, is increasingly
exploited to design and manipulate topological phases of matter. In this work we study …

Valence and conduction bands in nodal loop semimetals (NLSMs) touch along closed loops
in momentum space. If such loops can proliferate and link intricately, NLSMs become exotic …
