Quantum Heat Engine With Multi-Level Quantum Systems
H. T. Quan, P. Zhang, C. P. Sun
By reformulating the first law of thermodynamics in the fashion of quantum-mechanical operators on the parameter manifold, we propose a universal class of quantum heat engines (QHE…

Effective boson-spin model for nuclei ensemble based universal quantum memory
Z. Song, P. Zhang, T. Shi +1
We study the collective excitation of a macroscopic ensemble of polarized nuclei fixed in a quantum dot. Under the approximately homogeneous condition that we explicitly present in…

Quasi-spin wave quantum memories with dynamic symmetry
C. P. Sun, Y. Li, X. F. Liu
For the two-mode exciton system formed by the quasi-spin wave collective excitation of many atoms fixed at the lattice sites of a crystal, we discover a dynamic symmetry depict…
