Four-connected triangulations of planar point sets
Ajit Arvind Diwan, Subir Kumar Ghosh, Bodhayan Roy
In this paper, we consider the problem of determining in polynomial time whether a given planar point set of points admits 4-connected triangulation. We propose a necessary…
Spontaneous Photoemission From Metamaterial Junction: A Conjecture
Subir Ghosh, Santanu K. Maiti
The possibility of spontaneous photon pair emission from a normal material - metamaterial junction is investigated in a quantum field theory setting. We consider a pair of photons…
An Algorithm for Computing Constrained Reflection Paths in Simple Polygon
Arijit Bishnu, Subir Kumar Ghosh, Partha Pratim Goswami +2
Let be a source point and be a destination point inside an -vertex simple polygon . Euclidean shortest paths and minimum-link paths between and inside hav…
Quantum Gravity Effects in Geodesic Motion and Predictions of Equivalence Principle Violation
Subir Ghosh
We show that the Equivalence Principle (EP) is violated by Quantum Gravity (QG) effects. The predicted violations are compared to experimental observations for Gravitational Redshi…
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…
