Spatially-modulated Superfluid States in Fermionic Optical Ladder Systems with Repulsive Interactions
Yusuke Fujihara, Akihisa Koga, Norio Kawakami
We investigate two-component ultracold fermionic atoms with repulsive interactions trapped in an optical lattice with a ladder structure. By applying the Bogoliubov-de Gennes equat…
Variational Monte Carlo analysis of the Hubbard model with a confining potential: one-dimensional fermionic optical lattice systems
Yusuke Fujihara, Akihisa Koga, Norio Kawakami
We investigate the one-dimensional Hubbard model with a confining potential, which may describe cold fermionic atoms trapped in an optical lattice. Combining the variational Monte…
Frustrated Ising model on the garnet lattice
Takuya Yoshioka, Akihisa Koga, Norio Kawakami
We investigate a frustrated Ising spin system on the garnet lattice composed of a specific network of corner-sharing triangles. By means of Monte Carlo simulations with the heat ba…
