Laser Cooling of two trapped ions: Sideband cooling beyond the Lamb-Dicke limit [PDF]

, 1998
We study laser cooling of two ions that are trapped in a harmonic potential and interact by Coulomb repulsion. Sideband cooling in the Lamb-Dicke regime is shown to work analogously to sideband cooling of a single ion.

Self‐Assembled Inorganic Nanomembrane Tubes: Rolled‐Up Piezoelectrics for Microacoustic Wave‐Based Actuators and Sensors

Advanced Materials, EarlyView.
This study demonstrates a self‐assembly process to generate free‐standing piezoelectric nanomembranes, forming ultracompact microtubular acoustic wave sensors and actuators. The miniaturized 3D piezoelectric platform reported in this work can be applied in telecommunication, energy harvesting, and acoustofluidics. Moreover, the 3D self‐assembly can add

Exopolysaccharides of Lactobacillus crispatus mediate key balancing interactions with the vaginal mucosa

npj Biofilms and Microbiomes
Lactobacillus crispatus is a dominant member of the healthy vaginal microbiota, yet the mechanisms by which it modulates host immunity remain poorly defined, in part due to the lack of tractable in vivo models.

Polymorph‐Specific Electronic Transduction in WO3 during Molecular Sensing

Advanced Materials, EarlyView.
Metal‐oxide polymorphs with similar surface chemistry can nevertheless exhibit distinct sensing properties. In γ‐ and ε‐WO3, analyte adsorption appears comparable; yet, only ε‐WO3 induces a pronounced lattice electronic perturbation that accommodates charge in sub‐conduction band minimum states.

Lamb's Problem

Bulletin of the Institute of Mathematics Academia Sinica NEW SERIES
Summary: We derive an explicit solution representation for the Lamb's problem. The solution formula is given in terms of the fundamental solutions of the d'Alembert wave equations, the Kirchhoff's formula in 3-D and the Hadamard's formula in 2-D, when the Poisson ratio \(\frac{1}{2} \lambda/(\lambda +\mu)\) is less than or equal to a critical value ...

Lamb shift in muonic helium ion [PDF]

, 2006
The Lamb shift (2P_{1/2}-2S_{1/2}) in the muonic helium ion (mu ^4_2He)^+ is calculated with the account of contributions of orders alpha^3, alpha^4, alpha^5 and alpha^6.
