In a magnetic crystal belonging to a monoaxial (tetragonal, hexagonal, or trigonal) chiral
space group, competition of the Dzyaloshinskii–Moriya interaction and ferromagnetic …

In recent years, predictive computational modeling has become a cornerstone for the study
of fundamental electronic, optical, and thermal properties in complex forms of condensed …

Solid understanding of current induced torques is a key to the development of current and
voltage controlled magnetization dynamics in ultrathin magnetic heterostructures. To …

Two hundred years ago, Ampère discovered that electric loops in which currents of electrons
are generated by a penetrating magnetic field can mutually interact. Here we show that …

We investigate the twisted topology of the complex eigenspectrum of a one-dimensional non-
Hermitian system under the influence of long-range unidirectional coupling. Unlike the …

In this paper, we demonstrate the emergence and disappearance of topological zero modes
(TZMs) in a coupled topolectrical (TE) circuit lattice. Specifically, we consider non-Hermitian …

We argue that spin-and valley-polarized metallic phases recently observed in graphene
bilayers and trilayers support chiral edge modes that allow spin waves to propagate …

An extension of the Heisenberg Hamiltonian is discussed that allows us to go beyond the
standard bilinear spin Hamiltonian taking into account various contributions due to multispin …

The concept of gauge field is a cornerstone of modern physics and the synthetic gauge field
has emerged as a new way to manipulate particles in many disciplines. In optics, several …

We study the rich properties of a topolectrical (TE) circuit array consisting of lossless basic
electrical components, such as capacitors and inductors, which can be designed to exhibit …
