The past few years have witnessed a surge of interest in non-Hermitian Floquet topological
matter due to its exotic properties resulting from the interplay between driving fields and non …

Topological materials, whether in solid state, photonic or acoustic systems, or other
domains, are characterized by bulk topological invariants that remain unchanged as long as …

Topological pumps have garnered substantial attention in physics. However, the
requirement for slow evolution speed to satisfy adiabaticity greatly restricts their application …

Topological phases are robust against weak perturbations, but break down when disorder
becomes sufficiently strong. However, moderate disorder can also induce topologically …

Microscopic origins of charge currents and electromagnetic (EM) radiation generated by
them in spintronic THz emitters—such as, femtosecond laser pulse-driven single magnetic …

We develop a theory of adiabatic orbital pum**, highlighting qualitative differences from
spin pum**. An oscillating magnetic field pumps not only orbital angular momentum …

Non-Abelian optics has emerged as a promising research field with the potential to
revolutionize our understanding of light–matter interactions and enable new applications in …

Non-Abelian phenomena arise when the sequence of operations on physical systems
influences their behaviors. By possessing internal degrees of freedom such as polarization …

We study Thouless pumps, ie, adiabatic topological transport, in an interacting spin chain
described by the dimerized XXZ Hamiltonian. In the noninteracting case, quantized …

The dynamics of topological boundary modes in both periodic and quasi-periodic
electromechanical metastructures is investigated, with a focus on their applications to …
