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.…
Vortex confinement transitions in the modified Goldstone model
Michikazu Kobayashi, Gergely Fejős, Chandrasekhar Chatterjee +1
The modified XY model is a variation of the XY model extended by a half periodic term, exhibiting a rich phase structure. As the Goldstone model, also known as the linear O(2) mode…
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…
Topological defects at the boundary of neutron superfluids in neutron stars
Shigehiro Yasui, Chandrasekhar Chatterjee, Muneto Nitta
We study surface effects of neutron superfluids in neutron stars. superfluids are in uniaxial nematic (UN), D biaxial nematic (BN), or D BN phas…
Effects of strong magnetic fields on neutron superfluidity with spin-orbit interactions
Shigehiro Yasui, Chandrasekhar Chatterjee, Muneto Nitta
We discuss neutron phases in the core of neutron stars in strong magnetic field (magnetars). The neutron pairing provides a wide variety of condensates, suc…
Reexamining Ginzburg-Landau theory for neutron superfluidity in neutron stars
Shigehiro Yasui, Chandrasekhar Chatterjee, Michikazu Kobayashi +1
The Ginzburg-Landau (GL) effective theory is a useful tool to study a superconductivity or superfluidity near the critical temperature, and usually the expansion up to the 4th orde…
