We analyze the dephasing effects on the backscattering behavior of the helical surface states.We show that dephasing effects can cause backscattering and de
Thermal rectification in Si cone-shaped nanowires has been studied using molecular dynamics simulation.We found that thermal rectification can be effectivel
Existence of Majorana fermions in superconducting systems attracts much interest recently.A number of researches have been predicting Majorana fermions m sp
We analyze and compare the effect of spatial and spin anisotropy on spin conductivity in a two dimensional S = 1/2 Heisenberg quantum magnet on a square lat
The electronic structure,phonon dispersions,and electron-phonon(EP)coupling in FeSe monolayers on SrTi03(STO)substrates are studied based on the first-princ
We study the interlayer bias-voltage modulated electronic properties in two-dimensional hexagonal lattice bilayers,especially make a comparative investigati
The electronic structure and magnetic structures of recently discovered BaTi2Sb2O was studied from first-principles calculations.In the nonmagnetic state,th
The quasiparticle interference(QPI)in Sr2Ru04 is theoretically studied based on two different pairing models in order to propose an experimental method to t
