Polarization-dependent transformation of a paraxial beam upon reflection and refraction: a real-space approach
Polarization-dependent transformation paraxial beam real-space approach reflection refraction
2011/8/3
Abstract: We analyze the paraxial beam transformation upon reflection and refraction at a plane boundary. In contrast to the usual approach dealing with the beam angular spectrum, we apply the continu...
Nonlinear transformation optics and engineering of the Kerr effect
Nonlinear transformation optics engineering of the Kerr effect Materials Science
2011/8/1
Abstract: The concept of transformation optics is extended to nonlinear electrodynamics. It is shown that transformation optics favors implicit constitutive relations in terms of energy densities D.E ...
Entanglement in Coupled Harmonic Oscillators via Unitary Transformation
harmonic oscillator unitary transformation purity entanglement
2011/7/28
Abstract: We develop an approach to study the entanglement in two coupled harmonic oscillators. We start by introducing an unitary transformation to end up with the solutions of the energy spectrum. T...
Transformation Optics in Nonvacuum Initial Dielectric Media
Transformation Optics Nonvacuum Initial Dielectric Media
2010/11/12
Previous formulations of transformation optics have generally been restricted to transformations from relatively simple initial media, such as the vacuum, because of limitations due to their non-cova...
By a quantum version of the Arnold transformation of classical mechanics, all quantum dynamical systems whose classical equations of motion are non-homogeneous linear second-order ordinary differenti...
Extension of the Morris-Shore transformation to multilevel ladders
Extension Morris-Shore transformation multilevel ladders
2010/10/29
We describe situations in which chains of N degenerate quantum energy levels, coupled by time-dependent external fields, can be replaced by independent sets of chains of length N, N-1,...,2 and sets o...
