A consistent approach to the path integral formalism of quantum mechanics based on the maximum length uncertainty
Souvik Pramanik
We have developed a proper path integral formalism consistent with the deformed version of the quantum mechanics which contains a maximum observable length scale at the order of th…
Even parity potential for spacetimes with Gaussian matter source and its associated QNM spectra
Souvik Pramanik, Kumar Das
We have obtained the general form of even mode potential function for the gravitational perturbation of a static spherically symmetric spacetime. Considering the minimal-spread Gau…
Quasinormal mode spectra for odd parity perturbations in spacetimes with smeared matter sources
Kumar Das, Souvik Pramanik, Subir Ghosh
We have found the Quasi Normal Mode (QNM) frequencies of a class of static spherically symmetric spacetimes having a {\it {smeared}} matter distribution, parameterized by - an…
Gravitationally influenced particle creation models and late-time cosmic acceleration
Supriya Pan, Barun Kumar Pal, Souvik Pramanik
In this work we focus on the gravitationally influenced adiabatic particle creation process, a mechanism that does not need any dark energy or modified gravity models to explain th…
Particle on a Torus Knot: Constrained Dynamics and Semi-Classical Quantization in a Magnetic Field
Praloy Das, Souvik Pramanik, Subir Ghosh
Kinematics and dynamics of a particle moving on a torus knot poses an interesting problem as a constrained system. In the first part of the paper we have derived the modified sympl…
AdS-CFT Correspondence in Noncommutative background, related thermodynamics and Holographic Superconductor in Magnetic Field
Souvik Pramanik, Subir Ghosh
In this work, we formulate a Non-Commutative (NC) extension of AdS-CFT correspondence that is manifested in the modification of behavior of a holographic superconductor. The noncom…
Scalar field cosmology modified by the Generalized Uncertainty Principle
Andronikos Paliathanasis, Supriya Pan, Souvik Pramanik
We consider quintessence scalar field cosmology in which the Lagrangian of the scalar field is modified by the Generalized Uncertainty Principle. We show that the perturbation term…
Effects of a Maximal Energy Scale in Thermodynamics for Photon Gas and Construction of Path Integral
Sudipta Das, Souvik Pramanik, Subir Ghosh
In this article, we discuss some well-known theoretical models where an observer-independent energy scale or a length scale is present. The presence of this invariant scale necessa…
The Path Integral Quantization corresponding to the Deformed Heisenberg Algebra
Souvik Pramanik, Mir Faizal, Mohamed Moussa +1
In this paper, the deformation of the Heisenberg algebra, consistent with both the generalized uncertainty principle and doubly special relativity, has been analyzed. It has been o…
Conformal Invariance in noncommutative geometry and mutually interacting Snyder Particles
Souvik Pramanik, Subir Ghosh, Probir Pal
A system of relativistic Snyder particles with mutual two-body interaction that lives in a Non-Commutative Snyder geometry is studied. The underlying novel symplectic structure is…
Implication of geodesic equation in Generalized Uncertainty Principle framework
Souvik Pramanik
The generalized uncertainty principle (GUP) corrected modified relativistic particle model has been derived in curved space-time. From this modified model, the equation of motion (…
Noncommutative Extension of AdS-CFT and Holographic Superconductors
Souvik Pramanik, Sudipta Das, Subir Ghosh
In this Letter, we consider a Non-Commutative (NC) extension of AdS-CFT correspondence and its effects on holographic superconductors. NC corrections are incorporated via the NC ge…
GUP-based and Snyder Non-Commutative Algebras, Relativistic Particle models and Deformed Symmetries: A Unified Approach
Souvik Pramanik, Subir Ghosh
We have developed a unified scheme for studying Non-Commutative algebras based on Generalized Uncertainty Principle (GUP) and Snyder form in a relativistically covariant point part…
Electrodynamics of a Generalized Charged Particle in Doubly Special Relativity Framework
Souvik Pramanik, Subir Ghosh, Probir Pal
In the present paper, dynamics of generalized charged particles are studied in the presence of external electromagnetic interactions. This particular extension of the free relativi…
Path Integral for non-relativistic Generalized Uncertainty Principle corrected Hamiltonian
Sudipta das, Souvik Pramanik
Generalized Uncertainty Principle (GUP) has brought the idea of existence of minimum measurable length in Quantum physics. Depending on this GUP, non-relativistic Hamiltonian at th…
