Recently, the finite-size corrections to the geometrical entanglement per lattice site in the spin-1/2 chain have been numerically shown to scale inversely with system size, and its prefactor b has been suggested to be possibly universal [Q-Q. Shi et

The supersymmetric QCD corrections to top quark pair production by {ital q{bar q}} annihilation in {ital p{bar p}} collisions are calculated in the minimal supersymmetric model. We present the analytic expressions of the corrections to the total {ita

Spontaneous symmetry breaking mechanism in quantum phase transitions manifests the existence of degenerate groundstates in broken symmetry phases. To detect such degenerate groundstates, we introduce a quantum fidelity as an overlap measurement betwe

A one-dimensional quantum spin model with the competing two-spin and three-spin interactions is investigated in the context of a tensor network algorithm based on the infinite matrix product state representation. The algorithm is an adaptation of Vid

A systematic analysis is performed for quantum phase transitions in a bond-alternative one-dimensional Ising model with a Dzyaloshinskii-Moriya (DM) interaction by using the fidelity of ground state wave functions based on the infinite matrix product

We have computed the O( alpha mt2/mw2) correction to the top-quark decay into a charged Higgs and a bottom quark in the minimal supersymmetric standard model. The analytic expression of such a correction to the decay width is given. The numerical res

Virtual effects of supersymmetry on the partial width and on the branching ratio are calculated in the minimal supersymmetric standard model. We found that the virtual gluino contribution to the width is negligibly small if the squark and gluino mass

We computed the O(αs) virtual gluino correction to t → H+b in the minimal supersymmetric standard model, and investigated the dependence of the process on gluino and squark masses. For some values of masses, the correction implies up to 8% reducti

Virtual corrections of squark-gluino coupling to the process Z to bb are calculated in the minimal supersymmetric standard model. The corrections typically imply a few percent ( approximately 3%) reduction in the branching ratio; depending strongly o
