采用重归一化Numerov算法求解关于超低温双原子碰撞问题的非含时薛定谔方程组。以39K-133Cs碰撞为例,研究了超低温下双原子Feshbach共振的性质。结果表明,重归一化Numerov算法可以很精确地描述超冷条件下碰撞过程。与改进的logarithmicderivative算法相比,在同等参数条件下,重归一化Numerov方法在计算效率上虽然有一定劣势,但在大格点步长参数范围内有着更好的稳定...
The stationary points of the Hamiltonian H of the classical XY chain with power law pair interactions (i. e., decaying like r− with the distance) are analyzed. For a class of “spinwave-type”st...
Many-body effects are at the very heart of diverse phenomena found in condensed-matter physics. One striking example is the Mott insulator phase where conductivity is suppressed as a result of a str...
Multiplicity, rapidity and transverse momentum distributions of hadrons produced both in inelastic and non-diffractive pp collisions at energies from ps = 200GeV to 14TeV are studied within the Monte ...

An interpretation of the ridge phenomenon found in pp collisions at 7 TeV is given in terms of enhancement of soft partons due to energy loss of semihard jets. A description of ridge formation in nuc...
We study CP violation and the contribution of the strong pion-pion interactions in the three-body B± →π±π∓π± decays within a quasi two-body QCD factorization approach. The short distance interac...
Systems with long-range interactions, while relaxing towards equilibrium, sometimes get trapped in long-lived non-Boltzmann quasistationary states (QSS) which have lifetimes that grow algebraically ...
The plasmon coupling in a nanorod dimer obeys the exponential size dependence according to the Universal Plasmon Ruler Equation. However, it was shown recently that such a model does not hold at short...
The production of J/y mesons is studied in pp collisions at p s = 7 TeV with the CMS experiment at the LHC. The measurement is based on a dimuon sample corresponding to an integrated luminosity of 314...
The CDF experiment at the Tevatron p¯p collider established that extensive and detailed exploration of the b–quark dynamics is possible in hadron collisions, with results competitive and suppleme...
Existence of frame invariant, maximum, time interval T, length L, and mass M is postulated. In the de Sitter universe - (1) the life span of universe,(2) the circumference of universe at the point of ...
The observation of W and Z bosons and a measurement of the production cross sections in proton proton collisions at ECM = 7 TeV are presented using data from the ATLAS experiment at the LHC.
We derive a theoretical description for dilute Bose gases as a loop expansion in terms of composite- eld propagators by rewriting the Lagrangian in terms of auxiliary elds related to the normal and a...
Measurements of W and Z cross-sections in pp collisions at ECM = 7TeV at the Large Hadron Collider are reported from the ATLAS experiment. From an observation of 118 leptonic W candidates, the inclusi...
