Quantum phase transition by employing trace distance along with the density matrix renormalization group
Da-Wei Luo, Jing-Bo Xu
We use an alternative method to investigate the quantum criticality at zero and finite temperature using trace distance along with the density matrix renormalization group. It is s…
Trace distance and scaling behavior of coupled cavity lattice at finite temperature
Da-Wei Luo, Jing-Bo Xu
We use an alternative approach to study the quantum phase transition in a coupled cavity lattice at finite temperature. As an illustrative example, we investigate the behaviors of…
Eigenstate Tracking in Open Quantum Systems
Jun Jing, Marcelo S. Sarandy, Daniel A. Lidar +2
Keeping a quantum system in a given instantaneous eigenstate is a control problem with numerous applications, e.g., in quantum information processing. The problem is even more chal…
Two-component Dirac equation
Da-Wei Luo, P. V. Pyshkin, Ting Yu +3
We provide an alternative approach to relativistic dynamics based on the Feshbach projection technique. Instead of directly studying the Dirac equation, we derive a two-component e…
