Consequences of 't Hooft's Equivalence Class Theory and Symmetry by Large Coarse Graining
X. F. Liu, C. P. Sun
According to 't Hooft (Class.Quantum.Grav. 16 (1999), 3263), quantum gravity can be postulated as a dissipative deterministic system, where quantum states at the ``atomic scale''ca…
Factoring the unitary evolution operator and quantifying entanglement
X. X. Yi, C. P. Sun
The unitary evolution can be represented by a finite product of exponential operators. It leads to a perturbative expression of the density operator of a close system. Based on the…
Finite temperature excitations of an inhomogneous trapped Bose gas with Feshbach resonances
X. X. Yi, D. L. Zhou, C. P. Sun +1
We derive and discuss the temperature dependance of the condensate and noncondensate density profile of a Bose-Einstein condensate gas with Feshbach resonance in a parabolic trap.…
Quantum Decoherence from Adiabatic Entanglement
C. P. Sun, D. L. Zhou, S. Yu +1
In order to understand quantum decoherence of a quantum system due to its interaction with a large system behaving classically, we introduce the concept of adiabatic quantum entang…
