Linh 来源：[J].Journal of the Physical Society of Japan(IF 2.087), 2020, Vol.89 (4) 摘要：First principles calculations are employed to evaluate the crystal structures, electronic properties, optical properties and carrier effective masses of pure and Lanthanum (La) or Gadolinium (Gd) doped bismuth tungstate (Bi2WO6). The calculated results revea...

As in the two-leg ladder model with diagonal hoppings, studied previously by the present authors, superconductivity is strongly enha...
 作者：Jun Ohkubo 来源：[J].Journal of the Physical Society of Japan(IF 2.087), 2020, Vol.89 (4) 摘要：A method to direct evaluation of expectations for Langevin systems (stochastic differential equations) is proposed. The method is based on a birth–death process which is derived using combinations of dummy variables and Itô formula. As a pedagogical example, a double-well sy...

Micrometer-sized samples were used f...

For a magnetic field parallel to the conductive layers...

If the quantities for TCF are...
