Bose-Einstein condensation and superfluidity on a fuzzy sphere
Vira Shyta, Flavio S. Nogueira, Ashley M. Cook
According to Hohenberg's theorem, Bose-Einstein condensation (BEC) in two dimensions is impossible for any temperature . By contrast, superfluidity does occur in two dimension…
Axion electrodynamics of Weyl superconductors with broken time-reversal symmetry
Vira Shyta, Jeroen van den Brink, Flavio S. Nogueira
The low-energy effective description of Weyl semimetals is defined by the axion electrodynamics, which captures the effects arising due to the presence of nodes of opposite chirali…
Chiral Meissner effect in time-reversal invariant Weyl superconductors
Vira Shyta, Jeroen van den Brink, Flavio S. Nogueira
Weyl semimetals have nodes in their electronic structure at which electrons attain a definite chirality. Due to the chiral anomaly, the non-conservation of charges with given chira…
Bosonization duality in 2+1 dimensions and critical current correlation functions in Chern-Simons Abelian Higgs model
Vira Shyta, Flavio S. Nogueira, Jeroen van den Brink
While the phase structure of the -symmetric Higgs theory is still under debate, a version of this theory with an additional Chern-Simons term was recently shown to…
Frozen deconfined quantum criticality
Vira Shyta, Jeroen van den Brink, Flavio S. Nogueira
There is a number of contradictory findings with regard to whether the theory describing easy-plane quantum antiferromagnets undergoes a second-order phase transition. The traditio…
Deconfined criticality and bosonization duality in easy-plane Chern-Simons two-dimensional antiferromagnets
Vira Shyta, Jeroen van den Brink, Flavio S. Nogueira
Two-dimensional quantum systems with competing orders can feature a deconfined quantum critical point, yielding a continuous phase transition that is incompatible with the Landau-G…
