Superfluidity in a gas of strongly-interacting bosons
G. M. Kavoulakis, Y. Yu, M. Ogren +1
We consider small systems of bosonic atoms rotating in a toroidal trap. Using the method of exact numerical diagonalization of the many-body Hamiltonian, we examine the transition…
Vortices and Edge Reconstruction in Small Quantal Systems at High Angular Momenta
M. Toreblad, Y. Yu, S. M. Reimann +2
Vortices can form when finite quantal systems are set to rotate. In the limit of small particle numbers the vortex formation in a harmonically trapped fermion system, with repulsiv…
Corrections to Scaling for the Two-dimensional Dynamic XY Model
H. P. Ying, B. Zheng, Y. Yu +1
With large-scale Monte Carlo simulations, we confirm that for the two-dimensional XY model, there is a logarithmic correction to scaling in the dynamic relaxation starting from a c…
Bosonization for 2D Interacting Fermion Systems: Non-Fermi Liquid Behavior
Y. Yu, Y. M. Li, N. d'Ambrumenil
Non-Fermi liquid behavior is found for the first time in a two-dimensional (2D) system with non-singular interactions using Haldane's bosonization scheme. The bosonized system is s…
