Search for New Physics with Atoms and Molecules
Advances in atomic physics, such as cooling and trapping of atoms and molecules and developments in frequency metrology, have added orders of magnitude to the precision of atom-based clocks and
TOPICAL REVIEW: Theory and applications of atomic and ionic polarizabilities
Atomic polarization phenomena impinge upon a number of areas and processes in physics. The dielectric constant and refractive index of any gas are examples of macroscopic properties that are largely
Watching dark solitons decay into vortex rings in a Bose-Einstein condensate.
We have created spatial dark solitons in two-component Bose-Einstein condensates in which the soliton exists in one of the condensate components and the soliton nodal plane is filled with the second
Hysteresis in a quantized superfluid ‘atomtronic’ circuit
The results suggest that the relevant excitations involved in hysteresis are vortices, and indicate that dissipation has an important role in the dynamics.
Blackbody-radiation shift in the Sr optical atomic clock
We evaluated the static and dynamic polarizabilities of the $5{s}^{2}\phantom{\rule{0.16em}{0ex}}{}^{1}{S}_{0}$ and $5s5p\phantom{\rule{0.16em}{0ex}}{}^{3}{P}_{0}^{o}$ states of Sr using the
Stationary solutions of the one-dimensional nonlinear Schrodinger equation: II. Case of attractive nonlinearity
In this second of two papers, we present all stationary so- lutions of the nonlinear Schrodinger equation with box or pe- riodic boundary conditions for the case of attractive nonlin- earity. The
Frequency-dependent polarizabilities of alkali-metal atoms from ultraviolet through infrared spectral regions
We present results of first-principles calculations of the frequency-dependent polarizabilities of all alkali-metal atoms for light in the wavelength range 300-1600 nm, with particular attention to
Controlling neutron orbital angular momentum
This work demonstrates OAM control of neutrons using macroscopic spiral phase plates that apply a ‘twist’ to an input neutron beam and demonstrates both the addition of quantum angular momenta along the direction of propagation, effected by multiple spiral phaseplates, and the conservation of topological charge with respect to uniform phase fluctuations.
Nearly linear light cones in long-range interacting quantum systems.
This work rules out the possibility that light cones of power-law interacting systems are bounded by a polynomial for α>2D and become linear as α→∞, suggesting that the velocity, as calculated from the slope of the light cone, may grow exponentially in time.
Tune-out wavelengths of alkali-metal atoms and their applications
Using first-principles calculations, we identify ''tune-out'' optical wavelengths, {lambda}{sub zero}, for which the ground-state frequency-dependent polarizabilities of alkali-metal atoms vanish.
