Classical Light Beams and Geometric Phases
N. Mukunda, S. Chaturvedi, R. Simon
We present a study of geometric phases in classical wave and polarisation optics using the basic mathematical framework of quantum mechanics. Important physical situations taken fr…
Effects of Noncommutativity on the Black Hole Entropy
Kumar S. Gupta, E. Harikumar, Tajron Juric +2
In this paper the BTZ black hole geometry is probed with a noncommutative scalar field which obeys the -Minkowski algebra. The entropy of the BTZ black hole is calculated using…
Phase Stability and Thermoelectric Properties of the Mineral FeS2: An Ab Initio Study
Vijay Kumar Gudelli, V. Kanchana, S. Appalakondaiah +2
First principles calculations were carried out to study the phase stability and thermoelectric properties of the naturally occurring marcasite phase of FeS at ambient condition…
High Pressure Study of Lithium Azide from Density-Functional Calculations
K. Ramesh Babu, Ch. Bheema Lingam, Surya P. Tewari +1
The structural, electronic, optical and vibrational properties of LiN under high pressure have been studied using plane wave pseudopotentials within the generalized gradient ap…
Electronic topological transition in LaSn under pressure
Swetarekha Ram, V. Kanchana, G. Vaitheeswaran +3
The electronic structure, Fermi surface and elastic properties of the iso-structural and iso-electronic LaSn and YSn intermetallic compounds are studied under pressure with…
Computational study of structural, electronic and optical properties of crystalline NHN
N. Yedukondalu, Vikas D. Ghule, G. Vaitheeswaran
A systematic computational study on the structural, electronic, bonding, and optical properties of orthorhombic ammonium azide (NHN) has been performed using planewave pseu…
