Lower (negative) bounds on the static electric susceptibility of non-equilibrium cubic crystals
R. Dutta, P. D. Wurzner, F. Castles
We use a classical, microscopic model of point-like dipolarizable entities (a model that is standard in the case of positive polarizability) and investigate its behavior for simple…
Magnetic structure of the magnetoelectric material BaMnGeO
A. Sazonov, H. Thoma, R. Dutta +7
A detailed investigation of BaMnGeO was performed in its low-temperature magnetoelectric state combining neutron diffraction with magnetization measurements on single c…
Unconventional magneto-resistance, and electronic transition in MnGe Weyl semimetal
Venus Rai, Subhadip Jana, Martin Meven +3
Weyl semimetals are well known for their anomalous transport effects caused by a large fictitious magnetic field generated by the non-zero Berry curvature. We performed the analysi…
Diffusion in the presence of correlated dynamical disorder and coherent exciton transfer in the non-Markovian limit
Rajesh Dutta, Biman Bagchi
The presence of static off-diagonal disorder promotes coherent exciton transport while diffusive motion can be recovered in the presence of fluctuations in the diagonal and off-dia…
Signatures of quantum coherence in the optical line shape of an exciton in the presence of dynamic disorder
Rajesh Dutta, Kaushik Bagchi, Biman Bagchi
We address the effects of quantum coherences on the optical line shape of an exciton in the presence of dynamic disorder. We consider a one-dimensional excitonic system that consis…
Exciton transfer dynamics and quantum diffusion in a lattice of two level systems: Interplay between transport and coherent population transfer dynamics
Rajesh Dutta, Biman Bagchi
We study excitation transfer dynamics in a lattice of two level systems characterized by dynamic disorder. The diagonal and off-diagonal energy disorders arise from the coupling of…
The role of trapped neutrino in dense stelllar matter and kaon condensation
R. Dutta
We investigate the effect of neutrino trapping on kaon condensation process and Equation of State (EOS) in a newly formed neutron star which is less than several seconds old. Using…
