Entropic Stabilization and Descriptors of Structural Transformation in High Entropy Alloys
Narendra Kumar, Umesh V. Waghmare
With first-principles theoretical analysis of the local structure using Bond Orientational Order parameters and Voronoi partitioning, we establish (a) HCPBCC structura…
Classical Orbital Magnetic Moment in a Dissipative Stochastic System
N. Kumar
We present an analytical treatment of the dissipative-stochastic dynamics of a charged classical particle confined bi-harmonically in a plane with a uniform static magnetic field d…
Classical Langevin dynamics of a charged particle moving on a sphere and diamagnetism: A surprise
N. Kumar, K. Vijay Kumar
It is generally known that the orbital diamagnetism of a classical system of charged particles in thermal equilibrium is identically zero -- the Bohr-van Leeuwen theorem. Physicall…
Langevin dynamics in crossed magnetic and electric fields: Hall and diamagnetic fluctuations
Dibyendu Roy, N. Kumar
Based on the classical Langevin equation, we have re-visited the problem of orbital motion of a charged particle in two dimensions for a normal magnetic field crossed with or witho…
Landau diamagnetism revisited
S. Dattagupta, A. M. Jayannavar, N. Kumar
The problem of diamagnetism, solved by Landau, continues to pose fascinating issues which have relevance even today. These issues relate to inherent quantum nature of the problem,…
Correcting the quantum clock: conditional sojourn times
S. Anantha Ramakrishna, N. Kumar
Can the quantum-mechanical sojourn time be clocked without the clock affecting the sojourn time? Here we re-examine the previously proposed non-unitary clock, involving absorption/…
