Laser cooling and trapping of atoms H. J. Metcalf Department of Physics, State University of New York, Stony Brook, New York 11794 P. van der Straten Debye Institute, Department of Atomic- and Interface Physics, Utrecht University, P.O. Box 80.000, 3508 TA Utrecht, The Netherlands Received August 27, 2002; revised manuscript received November Ultracold atoms, produced by laser cooling and trapping, have led to recent advances in quantum information, quantum chemistry, and quantum sensors. A lack of ultraviolet narrow-band lasers precludes laser cooling of prevalent atoms such as hydrogen, carbon, oxygen, and nitrogen. Broadband pulsed lasers Neutral Atom Atomic Beam Cooling Laser Trap Atom Trapping Time These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves. Magneto-optical trapping combines the friction force of laser cooling with a “restoring” force depending on the atomic position.

Atom loss can be calculated from the evolution of phase-space distribution function W(q,p,t) through FPE with two boundary conditions, W(q,p= 2MU 0,t)=0 and W(q,p=0,t)=0, where U 0 is the maximum kinetic energy the cooling and trapping process can capture.

Laser Cooling and Trapping of Neutral Atoms 977 1 Introduction The combination of laser cooling and atom trapping has produced astounding new tools for atomic physicists [1].

of Physics, Faculty of Science, ANU, ACT) This paper introduces and reviews light forces, atom cooling and atom trapping. The emphasis is on the physics of the basic processes. In discussing conservative forces the semi-classical dressed states are used rather than the usual quantized field dressed states.

for atom trapping. The absorptive part of the dipole interaction in far-detuned light leads to residual photon scattering of the trapping light, which sets limits to the performance of dipole traps. In the following, we derive the basic equations for the dipole potential and the scat-tering rate by considering the atom as a simple oscillator

valuable for the mass measurements relevant for current atomic physics research. Problems And Solutions On Atomic, Nuclear And Particle Physics Taken as a whole, the book gives an overview of why traps for charged particles are such as vacuum systems, detection techniques, and different types of particle cooling, av A Zhakeyev · 2017 · Citerat av 98 — One way to increase the efficiency is to fabricate light trapping structures, such this method, due to the high thermal conductivity and capacity of the cooling fluid. place at nanoscale, predominantly in energy bonding one atom to another, "one-atom-at-a-time" chemical procedures on the highly radioactive atoms of 263Rf He organized 3-sessions on Liquid Metal Cooled Reactors at the ICONE-8 For resorcinol resins (used to trap metals) the NMR results provide a clean Innehåller cooling.

Pritchard Department of Physics, Massachusetts Institute of Technology, Cambridge, Massachusetts 02139 David J. Wineland cooling and trapping were employed 50 to observe for the first time a funda mental quantum-mechanical process: the transition of a single atom from one discrete energy level to another (a quantum jump). In this case the trap ping was relatively easy because the atom had been ionized, or stripped of one of its electrons.

research has traditionally been atoms, trapping has been achieved using resonant radia-tion pressure and/or forces from ﬁeld gradients acting on either the atoms’ magnetic moments or their induced electric dipole moments. The latter force is produced by the electric ﬁeld of a near-resonant, tightly focused laser beam. All of these traps have maximum depths, ex- When atomic ions are trapped and cooled, they form crystals whose minimum energy configurations are determined by a balance between the trap potentials and the ions’ mutual Coulomb repulsion.
