N-Mode Hamiltonians with Coordinate-Momentum Coupling Terms
The Virial theorem, which is related to the Feynman-Hellmann (FH) theorem, usually applies to Hamiltonians without coordinate-momentum coupling terms. In this paper we discuss when there are coordinate-momentu...

Decoherence of an Open System under Continuous Quantum Measurement of Energy
We study continuous quantum measurements (CQM) of energy of an open quantum system by Lindblad master equation. It turns out that the time-dependence of decoherence is identified. We conclude that the CQM of e...

Associated production of Υ(1S)W at LHC in next-to-leading order QCD
We investigate the complete next-to-leading order (NLO) QCD corrections to Υ(1S) + W production at the LHC, and predict theoretically the distribution of the Υ(1S) transverse momentum. We analyse the contribution...
