This review addresses the method of explicit calculations of interatomic exchange
interactions of magnetic materials. This involves exchange mechanisms normally referred to …

Multiple-Q states as represented by a magnetic skyrmion crystal and hedgehog crystal have
been extensively studied in recent years owing to their unconventional physical properties …

Magnetic nano-skyrmions develop quantized helicity excitations, and the quantum tunneling
between nano-skyrmions possessing distinct helicities is indicative of the quantum nature of …

Multiple-Q magnetic states, such as a skyrmion crystal, become a source of unusual
transport phenomena and dynamics. Recent theoretical and experimental studies clarified …

Environment is assumed to play a negative role in quantum mechanics, destroying the
coherence in a quantum system and, thus, randomly changing its state. However, for a …

Topological order is important in many aspects of condensed matter physics and has been
extended to bosonic systems. In this Letter we report on the nontrivial topology of the …

The quantum skyrmionic phase is modeled in a two-dimensional helical spin lattice. This
topological skyrmionic phase retains its nature in a large parameter space before moving to …

Although quantum simulation can give insight into elusive or intractable physical
phenomena, many quantum simulators are unavoidably limited in the models they mimic …

Skyrmions are topological magnetic textures that can arise in noncentrosymmetric
ferromagnetic materials. In most systems experimentally investigated to date, skyrmions …

We study the dynamics of quantum skyrmions under a magnetic field gradient using neural
network quantum states. First, we obtain a quantum skyrmion lattice ground state using …
