Kosterlitz-Thouless transition in two-dimensional superfluid
A. M. Begun, A. V. Molochkov, K. L. Zarembo +1
The 2d superfluid (complex theory in two dimensions) undergoes Kosterlitz-Thouless transition driven by phase fluctuations of the superfluid order parameter. We study the tra…

Vortex wall phase in fractonic XY-plaquette model on square lattice
A. M. Begun, M. N. Chernodub, V. A. Goy +1
The XY-plaquette model is the most straightforward lattice realization of a broad class of fractonic field theories that host quasiparticles with restricted mobility. The plaquette…
