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…
