Dimensional reduction on a sphere
Gunnar Moller, Sergey Matveenko, Stephane Ouvry
The question of the dimensional reduction of two-dimensional (2d) quantum models on a sphere to one-dimensional (1d) models on a circle is adressed. A possible application is to lo…
Critical Binder cumulant in two-dimensional anisotropic Ising models
W. Selke, L. N. Shchur
The Binder cumulant at the phase transition of Ising models on square lattices with various ferromagnetic nearest and next-nearest neighbour couplings is determined using mainly Mo…
Insulating state of granular superconductors in a strong-coupling regime
I. S. Beloborodov, Ya. V. Fominov, A. V. Lopatin +1
We analyze the possibility of the formation of a magnetic-field-induced insulating state in a two-dimensional granular superconductor with relatively strong intergranular coupling…
Production efficiency of Feshbach molecules in fermion systems
B. E. Dobrescu, V. L. Pokrovsky
We present a consistent nonequilibrium theory for the production of molecular dimers from a two-component quantum-degenerate fermion atomic gas, via a linear downward sweep of the…
