Three Faces of the Aharonov-Bohm Phase
Patrick Das Gupta
Beginning with the basic notions of quantum theory, impossibility of `trajectory' description for particles that ensues from uncertainty principle is discussed. Why the observed tr…
F. J. Dyson: The Man who would make Patterns and Disturb the Universe
Patrick Das Gupta
Freeman J. Dyson, a brilliant theoretical physicist and a gifted mathematician, passed away on 28 February 2020 at the age of 96. A vignette of his outstanding contributions to phy…
Born Rule and Finkelstein-Hartle Frequency Operator Revisited
Patrick Das Gupta
Character of observables in classical physics and quantum theory is reflected upon. Born rule in the context of measurement being an interaction between two quantum systems is disc…
Some exact stationary state solutions of a nonlinear Dirac equation in 2+1 dimensions
Patrick Das Gupta, Samiran Raj, Debapriya Chaudhuri
Graphene's honeycomb lattice structure is quite remarkable in the sense that it leads, in the long wavelength limit, to a massless Dirac equation description of nonrelativistic qua…
Study of Spectral Lag for Short GRBs
Varsha Gupta, Patrick Das Gupta, P. N. Bhat
This paper reports statistically significant correlations between various burst parameters, observed in a sample of 156 GRBs belonging to BATSE 4B catalog with T90 less than 2 s. T…
Morphological properties of Short Duration GRBs
Varsha Gupta, Patrick Das Gupta, P. N. Bhat
In this paper, we study a sample of 65 short duration bursts contained in the 3B catalogue. We fit the time profiles of these GRBs with lognormal functions and study various tempor…
