A symplectic geometric origin of universal quartic modified dispersion relations

Sanjib Dey, Mir Faizal

We show that quartic modifications of relativistic dispersion relations arise generically from deformation-quantized phase spaces under minimal kinematical assumptions relevant to…

Quantum-classical diagnostics and Bohmian inequivalence for higher time-derivative Hamiltonians

Sanjib Dey, Andreas Fring

We develop a Bohmian analysis of a two-dimensional ghost Hamiltonian and its mapping to the degenerate Pais-Uhlenbeck model. Using Gaussian wavepackets, we derive the corresponding…

Nitrogen-Vacancy-Mediated Magnetism in Sputtered GdN Thin Films

Pankaj Bhardwaj, Jyotirmoy Sarkar, Bubun Biswal +11

Among rare-earth nitrides (RENs), gadolinium nitride (GdN) stands out as a promising material for spintronics owing to its distinctive combination of semiconducting behavior, stron…

Global Well-Posedness and Numerical Approximation of a Coupled Darcy-Convection-Diffusion System with Exponential Nonlinearity

Sahil Kundu, Amiya Kumar Pani, Manoranjan Mishra

This paper investigates density driven flow in porous media, focusing on the roles of viscosity contrast, density contrast, and linear adsorption. In this setup, the fluid on top i…
