Fidelity at Berezinskii-Kosterlitz-Thouless quantum phase transitions
G. Sun, A. K. Kolezhuk, T. Vekua
We clarify the long-standing controversy concerning the behavior of the ground state fidelity in the vicinity of a quantum phase transition of the Berezinskii-Kosterlitz-Thouless t…

Topological order-by-disorder in orbitally degenerate dipolar bosons in zig-zag lattice
G. Sun, T. Vekua
Spinor bosons offer conceptually simple picture of macroscopic quantum behavior of topological order-by-disorder: Paramagnetic state of two-component dipolar bosons in orbitally de…
