Depinning and creep motion in glass states of flux lines
Mengbo Luo, Xiao Hu
Using dynamical computer simulation we have investigated vortex matters in glass states. A genuine continuous depinning transition is observed at zero temperature, which also gover…
Effective field theory with a -vacua structure for 2d spin systems
Akihiro Tanaka, Xiao Hu
We construct a nonlinear sigma (NL) model description of 2+1d spin systems, by coupling together antiferromagnetic spin chains via interchain exchange terms. Our mapping incorpo…
Energy landscape and shear modulus of interlayer Josephson vortex systems
Yoshihiko Nonomura, Xiao Hu
The ground state of interlayer Josephson vortex systems is investigated on the basis of a simplified Lawrence-Doniach model in which spatial dependence of the gauge field and the a…
Magnetic and Electronic Properties of the New Ferrimagnet Sr8CaRe3Cu4O24
Masanori Kohno, Xiangang Wan, Xiao Hu
Magnetic and electronic properties of the recently-discovered material Sr8CaRe3Cu4O24 were investigated by means of a quantum Monte Carlo simulation, the Green function method and…
Anomalous impurity effect on magnetization in frustrated one-dimensional ferro- and ferrimagnets
Masanori Kohno, Xiao Hu
Significant decrease of spontaneous magnetization in frustrated one-dimensional ferro- and ferrimagnets due to non-magnetic impurities is predicted. Using the density-matrix renorm…
