Exceptional point in a coupled Swanson system
Bijan Bagchi, Rahul Ghosh, Sauvik Sen
We propose an interacting nonhermitian model described by a two-mode quadratic Hamiltonian along with an interaction term to locate and analyze the presence of an exceptional point…
Position-dependent mass Dirac equation and local Fermi velocity
Rahul Ghosh
We present a new approach to study (1+1)-dimensional Dirac equation in the background of an effective mass by exploiting the possibility of a position-dependent fermi velocity…
Random density matrices: Analytical results for mean root fidelity and mean square Bures distance
Aritra Laha, Agrim Aggarwal, Santosh Kumar
Bures distance holds a special place among various distance measures due to its several distinguished features and finds applications in diverse problems in quantum information the…
Dirac Hamiltonian in a supersymmetric framework
Bijan Bagchi, Rahul Ghosh
We investigate the most general form of the one-dimensional Dirac Hamiltonian in the presence of scalar and pseudoscalar potentials. To seek embedding of supersymmetry (SUSY)…
