Quantum lithography by coherent control of classical light pulses.
The smallest spot in optical lithography and microscopy is generally limited by diffraction. Quantum lithography, which utilizes interference between groups of N entangled photons, was recently proposed to beat the diffraction limit by a factor N. Here we propose a simple method to obtain N photons interference with classical pulses that excite a narrow multiphoton transition, thus shifting the...

متن کاملClassical-Wigner Phase Space Approximation to Cumulative Matrix Elements in Coherent Control
The classical limit of the Wigner-Weyl representation is used to approximate products of boundcontinuummatrix elements that are fundamental to many coherent control computations. The range of utility of the method is quantified through an examination of model problems, single-channel Na2 dissociation and multi-arrangement channel photodissociation of CH2IBr. Very good agreement with the exact q...
متن کاملPropagation of Coherent Light Pulses with PHASE
The current status of the software package PHASE for the propagation of coherent light pulses along a synchrotron radiation beamline is presented. PHASE is based on an asymptotic expansion of the Fresnel-Kirchhoff integral (stationary phase approximation) which is usually truncated at the 2 order. The limits of this approximation as well as possible extensions to higher orders are discussed. Th...
متن کاملClassical Phase Space Structure Induced by Spontaneous Symmetry Breaking
The collective dynamics of a many-body system is described as a special case of low-energy quantum dynamics, occurring when the ground state breaks a continuous symmetry of the Hamiltonian. This approach is applied to the spontaneous breaking of the rotational symmetry of a nuclear Hamiltonian. It is shown that the excitation operator of the isovector low-lying angular oscillations in deformed ...
