Control of a qubit state by a soliton propagating through a Heisenberg spin chain
S. Varbev, I. Boradjiev, R. Kamburova +1
We demonstrate that nonlinear magnetic solitary excitations (solitons) traveling through a Heisenberg spin chain may be used as a robust tool capable of coherent control of the qub…

Energy spectra of a spin- XY spin molecule interacting with a single mode field cavity: Numerical study
H. Tonchev, A. A. Donkov, H. Chamati
In a previous paper [J. Phys.: Conf. Ser. 682 (2016) 012032}, arXiv:1605.05593] we studied analytically the energy spectra of a finite-size spin XY chain (molecule) coup…

Interaction of a single mode field cavity with the 1D XY model: Energy spectrum
H. Tonchev, A. A. Donkov, H. Chamati
In this work we use the fundamental in quantum optics Jaynes-Cummings model to study the response of spin chain to a single mode of a laser light falling on one of the s…
