Topological entanglement entropy to identify topological order in quantum skyrmions
Vipin Vijayan, L. Chotorlishvili, A. Ernst +3
We study the topological entanglement entropy and scalar chirality of a topologically ordered skyrmion formed in a two-dimensional triangular lattice. Scalar chirality remains a sm…
Topological dynamical quantum phase transition in a quantum skyrmion phase
Vipin Vijayan, L. Chotorlishvili, A. Ernst +3
Quantum skyrmionic phase is modelled in a 2D helical spin lattice. This topological skyrmionic phase retains its nature in a large parameter space before moving to a ferromagnetic…
Semiclassical theory for plasmons in two-dimensional inhomogeneous media
T. M. Koskamp, M. I. Katsnelson, K. J. A. Reijnders
The progress in two-dimensional materials has led to rapid experimental developments in quantum plasmonics, where light is manipulated using plasmons. Although numerical methods ca…
