Different realizations of kappa-momentum space and relative-locality effect
Stjepan Meljanac, Anna Pachol, Andjelo Samsarov +1
We consider different realizations for the momentum sector of kappa-Poincare Hopf algebra, which is associated with a curved momentum space. We show that the notion of the particle…
Effect of topological defects and Coulomb charge on the low energy quantum dynamics of gapped graphene
Baishali Chakraborty, Kumar S. Gupta, Siddhartha Sen
We study the combined effect of a conical topological defect and a Coulomb charge impurity on the dynamics of Dirac fermions in gapped graphene. Beyond a certain strength of the Co…
Phase structures in fuzzy geometries
T R Govindarajan, S. Digal, K. S. Gupta +1
We study phase structures of quantum field theories in fuzzy geometries. Several examples of fuzzy geometries as well as QFT's on such geometries are considered. They are fuzzy sph…
