Interactive specification acquisition via scenarios: A proposal [PDF]

Some reactive systems are most naturally specified by giving large collections of behavior scenarios. These collections not only specify the behavior of the system, but also provide good test suites for validating the implemented system.

Influence of temperature fluctuations on plasma turbulence investigations with Langmuir probes

, 2011
The reliability of Langmuir probe measurements for plasma-turbulence investigations is studied on GEMR gyro-fluid simulations and compared with results from conditionally sampled I-V characteristics as well as self-emitting probe measurements in the near

Sub-Doppler laser cooling of fermionic 40K atoms in three-dimensional gray optical molasses

, 2012
We demonstrate sub-Doppler cooling of 40K on the D_1 atomic transition. Using a gray molasses scheme, we efficiently cool a compressed cloud of 6.5x10^8 atoms from ~ 4\mK to 20uK in 8 ms.

Superfluid motion and drag-force cancellation in a fluid of light

, 2018
Quantum fluids of light merge many-body physics and nonlinear optics, through the study of light propagation in a nonlinear medium under the shine of quantum hydrodynamics. One of the most outstanding evidence of light behaving as an interacting fluid is

Improvement of radiation hardness for a novel InP-based HEMT with graded In1-xGaxAs channel layer and double Si-doped structure

Results in Engineering
To enhance the radiation resistance of the InP-based HEMT, a novel structure incorporating a graded In1-xGaxAs channel layer and double Si-doped structure (DPLC-HEMT) is proposed.

Probing the light induced dipole-dipole interaction in momentum space

, 2005
We theoretically investigate the mechanical effect of the light-induced dipole-dipole interaction potential on the atoms in a Bose-Einstein condensate. We present numerical calculations on the magnitude and shape of the induced potentials for different ...

High-order optical nonlinearity at low light levels

, 2011
We observe a nonlinear optical process in a gas of cold atoms that simultaneously displays the largest reported fifth-order nonlinear susceptibility \chi^(5) = 1.9x10^{-12} (m/V)^4 and high transparency.

Three-dimensional Doppler, polarization-gradient, and magneto-optical forces for atoms and molecules with dark states

, 2017
We theoretically investigate the damping and trapping forces in a three-dimensional magneto-optical trap (MOT), by numerically solving the optical Bloch equations. We focus on the case where there are dark states because the atom is driven on a "type-II"
