Quantum dynamics of double-qubits in a spin star lattice with an XY interaction
Jun Jing, Zhi-Guo Lü
The dynamics of two coupled spins-1/2 interacting with a spin-bath via the quantum Heisenberg XY coupling is studied. The pair of central spins served as a quantum open subsystem a…
Polynomial scheme for time evolution of open and closed quantum systems
Jun Jing, H. R. Ma
Based on the generation function of Laguerre polynomials, We proposed a new Laguerre polynomial expansion scheme in the calculation of evolution of time dependent Schrödinger equat…
Level crossing and quantum phase transition of the XY model
Jun Jing, H. R. Ma
The ground state of a one-dimensional spin-1/2 chain with periodical boundary condition in the Heisenberg XY model is investigated. We consider the spatial correlation and concurre…
Entanglement evolution for excitons of two separate quantum dots in a cavity driven by magnetic field
Jun Jing, Z. G. Lü, H. R. Ma
The time evolution of entanglement for excitons in two quantum dots embedded in a single mode cavity is studied in a ``spin-boson'' regime. It is found that although with the dissi…
