Quantum skyrmion dynamics studied by neural network quantum states

A Joshi, R Peters, T Posske - Physical Review B, 2024 - APS
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 …

Quantum skyrmion Hall effect in -electron systems

R Peters, J Neuhaus-Steinmetz, T Posske - Physical Review Research, 2023 - APS
The flow of electric current through a two-dimensional material in a magnetic field gives rise
to the family of Hall effects. The quantum versions of these effects accommodate robust …

Quantum Magnetic Skyrmion Operator

A Haller, SA Díaz, W Belzig, TL Schmidt - Physical Review Letters, 2024 - APS
We propose a variational wave function to represent quantum skyrmions as bosonic
operators. The operator faithfully reproduces two fundamental features of quantum …
