Chemical bonds of two vortex species with a generalized Josephson term and arbitrary charges
Chandrasekhar Chatterjee, Sven Bjarke Gudnason, Muneto Nitta
We consider the Abelian-Higgs model with two complex scalar fields and arbitrary positive integer charges with the addition of a higher-order generalization of the Josephson term.…
Aharonov-Bohm defects
Chandrasekhar Chatterjee, Muneto Nitta
We discuss what happens when a field receiving an Aharonov-Bohm (AB) phase develops a vacuum expectation value (VEV), with an example of an Alice string in a ga…
The effective action of a BPS Alice string
Chandrasekhar Chatterjee, Muneto Nitta
Recently a BPS Alice string has been found in a gauge theory coupled with a charged complex adjoint scalar field arXiv:1703.08971. It is a half BPS state preserv…
BPS Alice strings
Chandrasekhar Chatterjee, Muneto Nitta
When a charged particle encircles around an Alice string, it changes the sign of the electric charge. In this paper we find a BPS-saturated Alice string in gauge…
Meissner effect and a stringlike interaction
Chandrasekhar Chatterjee, Ishita Dutta Choudhury, Amitabha Lahiri
We find that a recently proposed interaction involving the vorticity current of electrons, which radiatively induces a photon mass in 3+1 dimensions in the low-energy effective the…
Geometry and Dynamics of a Coupled 4D-2D Quantum Field Theory
Stefano Bolognesi, Chandrasekhar Chatterjee, Jarah Evslin +3
Geometric and dynamical aspects of a coupled 4D-2D interacting quantum field theory - the gauged nonAbelian vortex - are investigated. The fluctuations of the internal 2D nonAbelia…
