Syed Kamrul Islam,Mohammad Rafiqul Haiderof light propagation - were due to Huygens (1690), who formulated the famous Huygens’ principle and Fresnel (1810) who derived this principle from a wave equation. With the formulation of Maxwell’s equations for electromagnetic waves by the end of the 19. century, the wave concept found its first spectacular application in physics.

Sensors and Instrumentation, Volume 5s light scattering experiments which probe the excitations of a condensate in both the free-particle and phonon regime. At higher light intensity, a new form of superradiance and phase-coherent matter wave amplification were observed. We also discuss properties of spinor condensates and describe stu

Evro Wee Sit,Chad Walber,Steve Seidlitzider both equilibrium and nonequilibrium phenomena. In the equilibrium case, we first derive the appropriate Hartree—Fock theory for the properties of the gas in the normal phase. We then turn our attention to the properties of the gas in the superfluid phase, and present a microscopic derivation of

E. Belloni,D. Milani,F. BraghinThis class of atom interferometers is analogous to optical interferometers, where slits or diffraction gratings have been used to divide and recombine beams of atoms. The gratings and slits can be either material structures or periodic light fields. Three months later, atom interferometers based on

Graphene Decoration for Gas Detectionze two fundamentally new optical principles, namely (i) the localization and trapping of light in a bulk material [.,.] and (ii) the complete inhibition of spontaneous emission [.,.] over a broad frequency range. The novel consequences of PBG materials flow directly from the realization and implemen

A. Capuano,A. Adami,V. Mulloni,L. Lorenzellitum to classical. We begin with a discussion of the conditional dynamics of simple systems. The resulting models are straightforward but suffice to illustrate basic physical ideas behind quantum measurements and decoherence. To discuss decoherence and . in a more general setting, we sketch perturbat
