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…
Quantum information diode based on a magnonic crystal
Rohit K. Shukla, Levan Chotorlishvili, Vipin Vijayan +4
Exploiting the effect of nonreciprocal magnons in a system with no inversion symmetry, we propose a concept of a quantum information diode, {\it i.e.}, a device rectifying the amou…
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…
Characteristic, dynamic, and near saturation regions of Out-of-time-order correlation in Floquet Ising models
Rohit Kumar Shukla, Sunil Kumar Mishra
We study characteristic, dynamic, and saturation regimes of the out-of-time-order correlation (OTOC) in the constant field Floquet system with and without longitudinal field. In th…
Directional scrambling of quantum information in helical multiferroics
M. Sekania, M. Melz, N. Sedlmayr +2
Local excitations as carriers of quantum information spread out in the system in ways governed by the underlying interaction and symmetry. Understanding this phenomenon, also calle…
Entanglement dynamics of two nitrogen vacancy centers coupled by a nanomechanical resonator
Z. Toklikishvili, L. Chotorlishvili, S. K. Mishra +4
In this paper we study the time evolution of the entanglement between two remote NV Centers (nitrogen vacancy in diamond) connected by a dual-mode nanomechanical resonator with mag…
