Quantification of Symmetry
Y. N. Fang, G. H. Dong, D. L. Zhou +1
Symmetry is conventionally described in a contrariety manner that the system is either completely symmetric or completely asymmetric. Using group theoretical approach to overcome t…
Single-photon scattering on a strongly dressed atom
Z. H. Wang, Yong Li, D. L. Zhou +2
We develop the generalized rotating-wave approximation (GRWA) approach (Phys. Rev. Lett. 99, 173601 (2007)) to study the single-photon scattering on a two-level system (TLS) with a…
Mosaic spin models with topological order
S. Yang, D. L. Zhou, C. P. Sun
We study a class of two-dimensional spin models with the Kitaev-type couplings in mosaic structure lattices to implement topological orders. We show that they are exactly solvable…
Fast entanglement of two charge-phase qubits through nonadiabatic coupling to a large junction
Y. D. Wang, P. Zhang, D. L. Zhou +1
We propose a theoretical protocol for quantum logic gates between two Josephson junction charge-phase qubits through the control of their coupling to a large junction. In the low e…
Normal ordering solution to quantum dissipation and its induced decoherence
G. R. Jin, D. L. Zhou, Yu-xi Liu +2
We implement the normal ordering technique to study the quantum dissipation of a single mode harmonic oscillator system. The dynamic evolution of the system is investigated for a r…
Idealization Second Quantization of Composite Particles
D. L. Zhou, S. Y. Yu, C. P. Sun
A practical method is developed to deal with the second quantization of the many-body system containing the composite particles. In our treatment, the modes associated with composi…
