Coherent amplification in laser cooling and trapping [PDF]

, 2006
The optical scattering force, behind Doppler cooling and magneto-optical trapping, may be amplified without incurring additional spontaneous emission by the state-dependent coherent deflection produced by a pulsed or chirped laser field.

CVD Grown Hybrid MoSe2–WSe2 Lateral/Vertical Heterostructures With Strong Interlayer Exciton Emission

Advanced Materials, EarlyView.
A scalable bottom‐up CVD methodology, based on liquid transition metal salt precursors, is presented for the controlled growth of two high‐quality MoSe2–WSe2 heterostructures (HSs): purely lateral (HS I) and hybrid lateral/vertical (HS II), by simply adjusting precursor concentration.

Towards sympathetic cooling of large molecules: Cold collisions between benzene and rare gas atoms [PDF]

, 2009
This paper reports on calculations of collisional cross sections for the complexes Z-CDH6 (X = 3He, 4He, Ne) at temperatures in the range 1)μK - 10K and shows that relatively large cross sections in the 103-105Å2 range are available for collisional ...

A Large Magneto‐Optical Trap of Cadmium Atoms Loaded From a Cryogenic Buffer Gas Beam

Natural Sciences
We demonstrate rapid loading of a magneto‐optical trap (MOT) of cadmium atoms from a pulsed cryogenic helium buffer gas beam, overcoming strong photoionization losses.

Conveyor-belt magneto-optical trapping of molecules

New Journal of Physics
Laser cooling is used to produce ultracold atoms and molecules for quantum science and precision measurement applications. Molecules are more challenging to cool than atoms due to their vibrational and rotational internal degrees of freedom.

Bandgap‐Dependent Band‐to‐Band Tunneling in Carbon Nanotube Transistors

Advanced Materials Interfaces, EarlyView.
We systematically investigate bandgap‐dependent BTBT in SWCNT transistors by comparing wide‐bandgap (6,5) (Eg≈1.13 eV), medium‐bandgap HiPco, and narrow‐bandgap Arc‐discharge (Eg≈0.59 eV) SWCNT networks. The narrow‐bandgap networks show stronger BTBT, higher off‐state leakage, and lower on/off ratio, while wide‐bandgap (6,5) devices suppress BTBT and ...

Scaling laws in velocity-selective coherent-population-trapping laser cooling [PDF]

, 1996
One-dimensional laser cooling based on velocity-selective coherent population trapping (VSCPT) has been investigated numerically through the solution of the optical Bloch equations and through a Monte Carlo analysis. The 1→1 and 2→2 transitions have been

Protein Corona Formation on Soft Nanocarriers Under Biomimetic Circulatory Flow

Advanced Materials Interfaces, EarlyView.
A biomimetic venous circulation system is developed to study protein corona formation on soft nanocarriers under physiological shear. Liposomes, PLGA nanoparticles, and lipid‐polymer hybrid nanoparticles acquire largely shared but material‐dependent protein coronas that alter surface properties and suppress cellular uptake, highlighting the importance ...
