Abstracts

Measurement of the Casimir force between parallel metallic surfaces Roberto Onofrio Physics Department, University of Padua & Los Alamos National Laboratory Wednesday, January 30, 2002 12:30 PM, Phillips Auditorium We report on the measurement of the Casimir force between conducting surfaces in a parallel configuration. The scaling of the force with the distance between the surfaces was tested in the 0.5-3.0 micrometer range, and the related force coefficient was determined at the 15% precision level. Implications of this measurement to understand gravity in the micrometer range and its possible extensions will also be discussed.

A Full Angular Momentum, Three Dimensional, Smooth Exterior Complex Dilated, Finite Element Method for Computing Resonances in Triatomic Molecules - Applied to a model of the NeICl van der Waals complex.    Dr. Sergey Levin Dept. of Physics, Stokholm University Department of Mathematical and Computational Physics, Institute for Physics, St. Petersburg University By combining a total angular momentum representation, the smooth exterior complex dilation technique and a three-dimensional finite element code, a study of some resonances in a model of an electronic surface of the van der Waals complex $NeICl$ was performed. For zero angular momentum, our results show good agreement with earlier calculations. Using the present formalism we believe that we are able to report the fully quantum mechanical calculation of predissociation widths for a triatomic molecule.

The Stark Ball: A Programmable Multipolar Environment Keith MacAdam University of Kentucky Abstract: As a natural evolution of my experiments with collisions of laser-excited Rydberg-state atoms in circular, coherent-elliptic, or directed linear states, I have designed, built and analyzed a three-dimensional elaboration of the Stark Barrel [J.L. Horn et al., Rev. Sci. Instrum. 69, 4086 (1998)]. Although it was conceived as a device to provide quasi-uniform electric fields, rapidly switchable to arbitrary directions in 3-d space, its potentialities for creating "designer" multipole potentials may be more significant. I will describe the device, bringing out some of its attractive mathematical features, and speculate on possible applications regarding orientational control of cold trapped neutral molecules and selective addressing of biological or pharmaceutical molecules, pollens, viruses, and other small electrically irregular particles.

Coherent Spin Manipulation and Quantum Computation in Double-Dot Molecules  J.M. Taylor   Dept. of Physics Harvard University (Lukin group) Monday, March 11, 2002 11:45 a.m. Pratt Conference Room The physics of spin in confined solid-state environments provides a window into the regime of scalable quantum computation. Double quantum-dots with long spin coherence lifetimes in each dot allow for a storage state, while adiabatic techniques for spin-dependent tunneling provide for coherent mapping of the state of the spin qubit into spatially separated states of the double-dot molecule. This technique can be used to perform fast and robust single- and multi-bit logic operations and to readout the states of individual bits. Issues of decoherence and limitations for a practical implementation are analyzed, and an extension to a many-qubit system is considered.

Coulomb Fourier transformation of the three-body Hamiltonian with a repulsive Coulomb interaction in one particle pair Dr. Sergey Leven St. Petersburg University  Date: Friday, March 15, 2002 Time: 11:45 Place: Pratt Conference Room A unitary transformation of the three-body Hamiltonian which describes a system of two charged and one neutral particles is constructed such that the Coulomb potential which acts between the charged particles is explicitly eliminated. The transformed Hamiltonian and in particular the transformed short-range pair interactions are worked out in detail. Thereby it is found that after transformation the short-range potential which acts between the charged particles is still of two-body type but occurs now in the ``Coulomb representation". In contrast, the short-range potential between the neutral and one of the charged particles becomes multiplied by a function that represents the three-body correlations originating from the action of the other charged particle on the considered pair. This function which is universal as it does not depend on any property of the short-range interacton is evaluated explicitly. Since no long-range Coulomb potential occurs in the transformed Hamiltonian, standard methods of short-range few-body scattering theory are applicable. >From the corresponding results the quantities pertaining to the original Hamiltonian can be found by the inverse transformation.

Ultrafast Spinning of Nanotubes by Circularly-polarized Light Dr. Petr Kral Department of Chemical Physics Weizmann Institute Date: Monday, April 1, 2002 Time: 11:45 Place: Pratt First, I give a brief overview of our recently studied transport problems in C and BN nanotubes, based on optical and frictional excitation. As an example, I describe in more details how we can spin C nanotubes with GHz frequencies by exciting its infrared vibrational modes with a circularly polarized light. Then, I present two problems with a complete population transfer in quantum systems with several competing channels. In one example, I demonstrate that a (racemic) mixture of an equal number of left-handed and right-handed chiral molecules can be separated by such techniques. In the next example, I give an analytic solution of the non-degenerate quantum control problem, where we can repetitively transfer $0-100~\%$ of population from arbitrary initial to arbitrary final wave packets, formed by non-degenerate eigenenergy states
