Scientists Demonstrate One Of Largest Quantum Simulators Yet,With 51 Atoms
Scientists Largest Quantum Simulators Yet 51 Atoms
2017/12/18
Physicists at MIT and Harvard University have demonstrated a new way to manipulate quantum bits of matter. In a paper published today in the journal Nature, they report using a system of finely tuned ...
Magneto-electric momentum transfer to atoms and molecules
Magneto-electric momentum atoms and molecules mechanical momentum
2011/8/11
Abstract: We report the first observation of mechanical momentum transferred to atoms and molecules upon application of crossed electric and magnetic fields. We identify this momentum as the microscop...
Optimized coupling of cold atoms into a fiber using a blue-detuned hollow-beam funnel
Optimized coupling cold atoms fiber blue-detuned hollow-beam funnel
2011/8/11
Abstract: We theoretically investigate the process of coupling cold atoms into the core of a hollow-core photonic-crystal optical fiber using a blue-detuned Laguerre-Gaussian beam. In contrast to the ...
Simulating quantum-optical phenomena with cold atoms in optical lattices

Efficient Guiding Cold Atoms Photonic Band Gap Fiber
2010/10/29
We demonstrate the first guiding of cold atoms through a 88 mm long piece of photonic band gap fiber. The guiding potential is created by a far-off resonance dipole trap propagating inside the fiber w...
We propose a methodology to construct excited states with a fixed angular momentum, namely,
“yrast excited states” of finite-size one-dimensional bosonic systems with periodic boundary conditions.The...
Collective photon emission from symmetric states created with Rydberg atoms on a ring lattice
Collective photon emission symmetric states Rydberg atoms
2010/10/21
We discuss the creation of non-classical light from collective atomic states that are prepared in a ring-shaped lattice. These states are realized by exploiting the strong interaction between atoms in...
Quantum chaos of a mixed, open system of kicked cold atoms
Quantum chaos mixed open system
2010/10/20
We suggest and demonstrate an all-optical experimental setup to observe and engineer entanglement oscillations of a pair of polarization qubits in a non-Markovian channel. We generate entangled photon...
Optical cooling and trapping of tripod-type atoms with rectified radiation forces
Laser cooling and trapping Rectified radiation forces
2010/10/27
A new scheme of three-dimensional (3D) all-optical (nonmagnetic) cooling and trapping of reso-
nant atoms, based on using of so-called rectified radiation forces in non-monochromatic light fields is ...
Determination of the number of atoms of the long-lived nuclide 126Sn by γ-ray spectrometry
126Sn activity measurement γ-ray spectrometry AMS
2009/12/24
By using HPGe γ-ray spectrometry, the activity of the long-lived fission product 126Sn in a SnOB2 sample was measured. The number of 126Sn atoms and the ratio of 126Sn to Sn were calculated based on t...
An Analytical Treatment of the Energy Spectrum of Hydrogen-Like Atoms Perturbed by a Generalized van der Waals Potential

Dependence of Transition Probabilities for Non-Linear Photo-Ionization of He Atoms on the Structure of the Exciting Radiation Pulses
Transition Probabilities Non-Linear Photo-Ionization He Atoms the Exciting Radiation Pulses
2010/10/14
We discuss the expected dependence of the probability transitions for 2-photon and 3-photon absorption in Helium gas on the spatial and temporal structure of the exciting radiation pulses. Regarding s...
