The tunneling conductance and tunneling magnetoresistance (TMR) are investigated inferromagnet/insulator/ferromagnet/insulator/d-wave superconductor (FM/I/FM/I/
We study a four-electron system in a vertically coupled four-layer quantum dot under a magnetic field by the exact diagonalization of the Hamiltonian matrix. We
The Ф meson productions in Au+Au and/or Pb+Pb collisions at AGS, SPS, RHIC, and LHC energies have been studied systematically with a hadron and string cascade
