Geometric Phases in Two-Level Mixing: From Neutral Mesons to Holonomic Qubits and Topological Majorana Modes
Swarup Sangiri, Utpal Sarkar, A Taraphder
We investigate the geometric structure of a Hermitian two-level mixing Hamiltonian motivated by neutral meson oscillations and its connections with qubit, fermionic, and topologica…
Geometric Phases in Kaon Decays and Baryogenesis
Swarup Sangiri, Utpal Sarkar
We studied the formalism for construction of Bargmann invariants (BIs) as quantum mechanical geometric phases and identified the CP invarince with the rephasing invariant phases in…
MSW effect with quark matter: Neutron Star as a case study
Hiranmaya Mishra, Prasanta K. Panigrahi, Sudhanwa Patra +1
With the recent findings from various astrophysical results hinting towards possible existence of strange quark matters with the baryonic resonances such as in the…
The parameter and the CDF W-mass anomaly: observations on the role of scalar triplets
Rituparna Ghosh, Biswarup Mukhopadhyaya, Utpal Sarkar
The -parameter, together with the W-and Z-masses, acts as Occam's razor on extensions of the electroweak symmetry breaking sectors. We apply this to non-doublet Higgs scenarios,…
Neutrino Condensate Dark Energy from TeV Scale Extra Dimensions
Ujjal Kumar Dey, Utpal Sarkar
We propose a new scenario of incorporating neutrino masses in models of TeV scale gravity and large extra dimensions, which can explain the dark energy problem through formation of…
Bargmann Invariants, Geometric Phases and Recursive Parametrization with Majorana Fermions
Rohan Pramanick, Swarup Sangiri, Utpal Sarkar
A generalized connection between the quantum mechanical Bargmann invariants and the geometric phases was established for the Dirac fermions. We extend that formalism for the Majora…
