Evidence of Two Distinct Dynamic Critical Exponents in Connection with Vortex Physics
Petter Minnhagen, Beom Jun Kim, Hans Weber
The dynamic critical exponent is determined from numerical simulations for the three-dimensional (3D) lattice Coulomb gas (LCG) and the 3D XY models with relaxational dynamics.…

Possibility of direct Mott insulator-to-superfluid transitions in weakly disordered boson systems
Sung Yong Park, Ji-Woo Lee, Min-Chul Cha +3
We study the zero-temperature phase transitions of a two-dimensional disordered boson Hubbard model at incommensurate boson densities. Via matrix diagonalization and quantum Monte…
