Dynamical symmetries of the anisotropic oscillator
Akash Sinha, Aritra Ghosh, Bijan Bagchi
It is well known that the Hamiltonian of an -dimensional isotropic oscillator admits an symmetry, making the system maximally superintegrable. However, the dynamical sym…
Analogue Hawking radiation as a tunneling in a two-level -symmetric system
Bijan Bagchi, Rahul Ghosh, Sauvik Sen
In the light of a general scenario of a two-level non-Hermitian -symmetric Hamiltonian we apply the tetrad-based method to analyze the possibility of analogue Hawking…
Refractive index profiles for a -symmetric optical structure
Bijan Bagchi, Rahul Ghosh, Sauvik Sen
By mapping the scalar Helmholtz equation (SHE) to the Schrodinger form we investigate the behaviour of optical structure when the refractive index distribution a…
Artificial Hawking radiation, weak pseudo-Hermiticity and Weyl semimetal blackhole analogy
Bijan Bagchi, Sauvik Sen
We examine the possibility of artificial Hawking radiation by proposing a non-PT-symmetric weakly pseudo-Hermitian two-band model containing a tilting parameter by pursuing Weyl se…
MOND and asymptotic safe gravity
Bijan Bagchi, Sauvik Sen
The modified Newtonian dynamics (MOND) paradigm is discussed in the context of asymptotic safe gravity. We estimate quantum correction to the logarithmic potential which is well kn…
So (2, 1) algebra, local Fermi velocity, and position-dependent mass Dirac equation
Bijan Bagchi, Rahul Ghosh, Christiane Quesne
We investigate the (1+1)-dimensional position-dependent mass Dirac equation within the confines of so(2,1) potential algebra by utilizing the character of a spatial varying Fermi v…
