Plasmonics:

pic-plasmonics

      Plasmonics is one of the hottest topics, on which a vast amount of research is being conducted by physicists, chemists, biologists and engineers. Plasmons are collective oscillations of free electrons in both metals and semiconductors. Nanoparticles of sizes 20nm-150nm ………..

 

 

Superluminal light propagation?

experiment

         It is really interesting that we, the physicists, can entangle two light pulses separated by 100s of km from each other, but we are unable to identify the propagation velocity of a pulse even in an ordinary dye solution  ………..

 

 

Quantum Optics with Bose-Einstein condensates:

pic-vortexSR

     BEC is not only a statistical phase transition, but also a quantum many body phase transition. The entanglement among all of the constituent atoms resists decoherence and randomized temperature fluctuations …………..

 

 

Quantum Precision Measurements:

pic2-BEC-membrane

     We detect the spatial position of a cantilever much more precisely by coupling it to a BEC. In atomic force microscopy (AFM), the position of the tip is measured by directly monitoring the displacement of the mechanical oscillator (cantilever) by the deflection of the laser beam. We monitor the motion of the cantilever indirectly by conducting measurements on the BEC .…………..

 

 

Photonic crystal from BEC vortices:

BECvortices

     A rotating BEC manifests the formation of vortices after a critical rotation frequency. Utilizing the index enhancement scheme, a triangular lattice of BEC vortices can generate both directional and complete photonic band gaps.
