Entanglement Induced by Noncommutativity: Anisotropic Harmonic Oscillator in Noncommutative space
Abhishek Muhuri, Debdeep Sinha, Subir Ghosh
Quantum entanglement, induced by spatial noncommutativity, is investigated for an anisotropic harmonic oscillator. Exact solutions for the system are obtained after the model is re…
Stimulated Hawking Emission From Electromagnetic Analogue Black Hole: Theory and Observation
Avijit Bera, Subir Ghosh
In this paper we consider possible analogue Hawking radiation from a normal dielectric and metamaterial composite, having an analogue horizon where the dielectric parameters vanish…
Hardness and approximation for the geodetic set problem in some graph classes
Dibyayan Chakraborty, Florent Foucaud, Harmender Gahlawat +2
In this paper, we study the computational complexity of finding the \emph{geodetic number} of graphs. A set of vertices of a graph is a \emph{geodetic set} if any vertex of…
Hawking radiation in a non-covariant frame: the Jacobi metric approach
Avijit Bera, Subir Ghosh, Bibhas Ranjan Majhi
The present paper deals with a reformulation of the derivation of Hawking temperature for static and stationary black holes. In contrast to the conventional approach, where the cov…
Geometric Phases for Classical and Quantum Dynamics: Hannay angle and Berry Phase for Loops on a Torus
Subir Ghosh
In this paper we have considered closed trajectories of a particle on a two-torus where the loops are noncontractible (poloidal and toroidal loops and knots embedded on a regular t…
Note on Morita Inequality for Planar Noncommutative Inverted Oscillator
Praloy Das, Subir Ghosh
A recent conjecture of Morita predicts a lower bound in temperature of a chaotic system, , being the Lyapunov exponent, which was demonstrated for a one…
