Thermal coherence of the Heisenberg model with Dzyaloshinsky-Moriya interactions in an inhomogenous external field
Manikandan Parthasarathy, Segar Jambulingam, Tim Byrnes +1
The quantum coherence of the two-site XYZ model with Dzyaloshinsky-Moriya (DM) interactions in an external inhomogenous magnetic field is studied. The DM interaction, the magnetic…
Time dynamics of quantum coherence and monogamy in a non-Markovian environment
Chandrashekar Radhakrishnan, Po-Wen Chen, Segar Jambulingam +2
The time evolution of the distribution and shareability of quantum coherence of a tripartite system in a non-Markovian environment is examined. The total coherence can be decompose…
Quantum coherence of the Heisenberg spin models with Dzyaloshinsky-Moriya interactions
Chandrashekar Radhakrishnan, Manikandan Parthasarathy, Segar Jambulingam +1
We study quantum coherence in a spin chain with both symmetric exchange and antisymmetric Dzyaloshinsky-Moriya couplings. Quantum coherence is quantified using the recently introdu…
