Evaluating Chern Topology in Discretized Brillouin Zones Using Bargmann Invariants
Swarup Sangiri, A Taraphder
We develop a finite-state geometric framework based on third-order Bargmann invariants for evaluating Chern numbers and characterizing local quantum-state geometry. Using gauge-inv…
Weyl Chirality and Kitaev Topology through Bargmann Invariants
Swarup Sangiri, A. Taraphder
We apply a finite-state geometric formulation based on Bargmann invariants to a two-band Weyl Hamiltonian and the one-dimensional Kitaev model of a p-wave superconductor. For the W…
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…
A Geometric Framework for CPT Violation in Neutral Meson Mixing Using Biorthogonal Bargmann Invariants
Swarup Sangiri
We develop a geometric framework for characterizing CPT violation in neutral meson systems using Bargmann invariants formulated within a biorthogonal description of the non-Hermiti…
Connected Sequential Bargmann Invariants and CP-Sensitive Geometric Correlation Structures in Neutral Meson Systems
Swarup Sangiri
We investigate connected sequential geometric structures in correlated neutral meson systems within the framework of Bargmann invariants. Building upon previously developed third-…
Bargmann Invariants and Correlated Geometric CP-Violating Structures in Neutral Meson Systems
Swarup Sangiri
Bargmann invariants provide a rephasing-invariant description of phase relations among quantum states and offer a geometric perspective on interference phenomena. In this work, we…
Correlation-Induced Interferometric Geometric Phase Difference in Entangled Neutral Meson Systems
Swarup Sangiri
We investigate the phase structure associated with correlated evolution in entangled neutral meson systems. Working within a rephasing-invariant interferometric framework, we const…
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…
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…
