Sweeping molecules with light

New Journal of Physics, 2017
Many areas of physics—precision measurements, quantum information, and physical chemistry, to name a few—are starting to benefit from the enormous advantages offered by cold and ultracold polar molecules.

Investigation of Nonlinear Vibration Behavior of Piezoelectric Micro-Beam Interacting with Spherical Nano Particles [PDF]

مجله مدل سازی در مهندسی, 2017
Today, piezoelectric micro-beams are widely used in atomic and friction force microscopies, thermal scanning microscopy, and biomass measurement due to their flexible structure, sensitivity to molecular and atomic forces, and very fast response.

Longitudinal Focusing and Cooling of a Molecular Beam [PDF]

Physical Review Letters, 2002
A neutral polar molecule experiences a force in an inhomogeneous electric field. This electric field can be designed such that a beam of polar molecules is exposed to a harmonic potential in the forward direction. In this potential the longitudinal phase-space distribution of the ensemble of molecules is rotated uniformly.

Simulating high-pressure surface reactions with molecular beams [PDF]

, 2023
Using a reactive molecular beam with high kinetic energy ($E_{kin}$) it is possible to speed gas-surface reactions involving high activation barriers ($E_{act}$), which would require elevated pressures ($P_0$) if a random gas with a Maxwell-Boltzmann ...

Isolated spin polarized hydrogen atoms as targets for laser-induced polarized electron acceleration

Frontiers in Physics
High density Spin Polarized Hydrogen (SPH) atoms, which can be prepared using UV dissociation of hydro-halide molecules, can be attractive as potential targets for laser ionization/acceleration schemes aiming to create high energy and high current ...

Low-temperature Collisions between Neutral Molecules in Merged Molecular Beams

CHIMIA, 2014
We have developed an experiment for the investigation of neutral molecular collisions in the gas phase at temperatures as low as 100 mK. These low temperatures are obtained by merging two supersonic expansions, using an electric and a magnetic ...

High-power Er:Y2O3 ceramic laser with an optical vortex beam output at ∼ 2.7 μm

Frontiers in Physics, 2023
We report on the direct generation of the high-power optical vortices at ∼2.7 μm from an Er:Y2O3 ceramic laser end-pumped by an annular pump beam using a simple capillary fiber-based pump beam conditioning scheme. Taking advantage of the thermal gradient

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

FEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...
