Exchange bias effect involved with tunneling magnetoresistance in polycrystalline La_{0.88}Sr_{0.12}CoO_3
M. Patra, S. Majumdar, S. Giri
We report the exchange bias (EB) effect along with tunneling magnetoresistance (MR) in polycrystalline La_{0.88}Sr_{0.12}CoO_3. Analogous to the shift in the magnetic hysteresis lo…
Tunneling across dilaton-axion black holes
Tanwi Ghosh, Soumitra SenGupta
In this work we study both charged and uncharged particles tunneling across the horizon of spherically symmetric dilaton-axion black holes using Parikh-Wilczek tunneling formalism.…
The making of ferromagnetic Fe doped ZnO nano-clusters
Nirmal Ganguli, Indra Dasgupta, Biplab Sanyal
In this letter, the authors present a study of the energetics and magnetic interactions in Fe doped ZnO clusters by ab-initio density functional calculations. The results indicate…
Particle Production within the Quark Meson Coupling Model
P. K. Panda, D. P. Menezes, C. Providência
Quark meson coupling (QMC) models can be successfully applied to the description of compact star properties in nuclear astrophysics as well as to nuclear matter. In the regime of h…
Doubly Charged Higgsinos at Tevatron
Durmuş A. Demir, Mariana Frank, Dilip K. Ghosh +3
Several supersymmetric models with extended gauge structures, motivated by either grand unification or by neutrino mass generation, predict light doubly-charged Higgsinos. In this…
A Randall-Sundrum scenario with bulk dilaton and torsion
Biswarup Mukhopadhyaya, Somasri Sen, Soumitra SenGupta
We consider a string-inspired torsion-dilaton-gravity action in a Randall-Sundrum brane world scenario and show that, in an effective four-dimensional theory on the visible brane,…
