Observation of Electromagnetically Induced Transparency and Slow Light in the Dark State - Bright State Basis of CPT
T. Lauprêtre, J. Ruggiero, R. Ghosh +2
Electromagnetically induced transparency (EIT) is observed in a three-level system composed of an excited state and two coherent superpositions of the two ground-state levels. This…
Enhancement in transition temperature and critical current density of CeO0.8F0.2FeAs by yttrium doping
J. Prakash, S. J. Singh, A. Banerjee +2
We report significant enhancement in superconducting properties of yttrium substituted Ce1-xYxOFFeAs superconductors. The polycrystalline samples were prepared by two step solid st…
Synthesis and characterization of ferromagnetic cobalt nanospheres, nanodiscs and nanocubes
D. Srikala, V. N. Singh, A. Banerjee +2
We report the synthesis of cobalt nanoparticles with different shapes and sizes by rapid pyrolysis of cobalt carbonyl in the presence of various surfactants. The size and shape of…
Design strategies for the creation of aperiodic nonchaotic attractors
Amitabha Nandi, Sourav K. Bhowmick, Syamal K. Dana +1
Parametric modulation in nonlinear dynamical systems can give rise to attractors on which the dynamics is aperiodic and nonchaotic, namely with largest Lyapunov exponent being nonp…
Effect of epitaxial strain on the magneto-electric coupling of YMnO3 thin films
A. K. Singh, M. Snure, A. Tiwari +1
We report synthesis of phase pure multiferroic YMnO3 thin films on sapphire (0001)with conducting ZnGaO buffer contact layer. Films were prepared by using pulsed laser deposition t…
Analysis of adiabatic transfer in cavity QED
Joyee Ghosh, R. Ghosh, Deepak Kumar
A three-level atom in a configuration trapped in an optical cavity forms a basic unit in a number of proposed protocols for quantum information processing. Through control with…
