Equivalent charge of photons in a very dense quantum plasma

Bistability in the Electric Current through a Quantum-Dot Capacitively Coupled to a Charge-Qubit

We investigate the electronic transport through a single-level quantum-dot which is capacitively coupled to a charge-qubit. By employing the method of nonequilibrium Green's functions, we calculate the electric current through quantum dot at finite bias voltages. The Green's functions and self-energies of the system are calculated perturbatively and self-consistently to the second order of inte...

Compressive and rarefactive dust-ion acoustic solitary waves in four components ‎quantum plasma with dust-charge variation

Based on quantum hydrodynamics theory (QHD), the propagation of nonlinear quantum dust-ion acoustic (QDIA) solitary waves in a ‎collision-less, unmagnetized four component quantum plasma consisting of electrons, positrons, ions and stationary negatively charged ‎dust grains with dust charge variation is investigated using reductive perturbation method. The charging current to the dust grains ca...

Quantum Mechanics of Photons

We present a short review of the concept of photon wave function and the photon wave equation which represents the Schrödinger equation for the photon. Photon wave function puts the photon on the same footing as particles with mass and presents the first quantization formulation for electromagnetic fields. Because the photon has zero rest mass and it always moves with speed of light, the quantu...

Very High Energy Photons in Universe

I discuss the recent exciting results of discovery of TeV photons from several galactic and extra-galactic sources, and highlight some objectives of VHE gamma ray astronomy that can be achieved in the near future by means of new generation ground-based detectors.

Light for the quantum. Entangled photons and their applications: a very personal perspective
