Renormalization group study of the conductances of interacting quantum wire systems with different geometries
Sourin Das, Sumathi Rao, Diptiman Sen
We examine the effect of interactions between the electrons on the conductances of some systems of quantum wires with different geometries. The systems include a wire with a stub i…
Dynamics and transport properties of Kondo insulators
N. S. Vidhyadhiraja, Victoria E. Smith, David E. Logan +1
A many-body theory of paramagnetic Kondo insulators is described, focusing specifically on single-particle dynamics, scattering rates, d.c. transport and optical conductivities. Th…
Bound and anti-bound soliton states for a quantum integrable derivative nonlinear Schrodinger model
B. Basu-Mallick, Tanaya Bhattacharyya, Diptiman Sen
We find that localized quantum N-body soliton states exist for a derivative nonlinear Schrodinger (DNLS) model within an extended range of coupling constant (ξ_q) given by 0 < | ξ_…
Gapless line for the anisotropic Heisenberg spin-1/2 chain in a magnetic field and the quantum axial next-nearest-neighbor Ising Chain
Amit Dutta, Diptiman Sen
We study the anisotropic Heisenberg (XYZ) spin-1/2 chain placed in a magnetic field pointing along the x-axis. We use bosonization and a renormalization group analysis to show that…
Mapping of Large Scale 158 micron [CII] Line Emission: Orion A
B. Mookerjea, S. K. Ghosh, H. Kaneda +5
We present the first results of an observational programme undertaken to map the fine structure line emission of singly ionized carbon ([CII] 157.7409 micron) over extended regions…
