The boundary S-matrix and the AdS to CFT dictionary [PDF]

open access: yes, 1999
An S-matrix analog is defined for anti-de Sitter space by constructing ``in'' and ``out'' states that asymptote to the timelike boundary. A derivation parallel to that of the LSZ formula shows that this ``boundary S-matrix'' is given directly by ...

A DPF analysis yields accurate analytic potentials for Li$_2(a\,^3\Sigma^+_u)$ and Li$_2(1\,^3 \Sigma^+_g)$ that incorporate 3-state mixing near the $1\,^3 \Sigma^+_g$-state asymptote [PDF]

open access: yes, 2011
A combined-isotopologue direct-potential-fit (DPF) analysis of optical and photoassociation spectroscopy data for the $a\,^{3}\Sigma_u^+$ and $1\,^3\Sigma_g^+$ states of Li$_2$ has yielded accurate analytic potential energy functions for both states. The

Faster and more precise isotopic water analysis of discrete samples by predicting the repetitions’ asymptote instead of averaging last values

open access: yesMethodsX, 2022
Water stable isotope analysis using Cavity Ring-Down Spectroscopy (CRDS) has a strong between-sample memory effect. The classic approach to correct this memory effect is to inject the sample at least 6 times and ignore the first two to three injections ...

Additive Equivalence in Turbulent Drag Reduction by Flexible and Rodlike Polymers [PDF]

open access: yes, 2005
We address the "Additive Equivalence" discovered by Virk and coworkers: drag reduction affected by flexible and rigid rodlike polymers added to turbulent wall-bounded flows is limited from above by a very similar Maximum Drag Reduction (MDR) asymptote ...

All-angle zero reflection at metamaterial surfaces

open access: yes, 2008
The authors study theoretically reflection on the surface of a metamaterial with a hyperbolic dispersion. It is found that reflection is strongly dependent on how the surface is terminated with respect to the asymptote of the hyperbolic dispersion. For a

Stability of Transparent Spherically Symmetric Thin Shells and Wormholes [PDF]

open access: yes, 2001
The stability of transparent spherically symmetric thin shells (and wormholes) to linearized spherically symmetric perturbations about static equilibrium is examined.

Turbulent Drag Reduction by Flexible and Rodlike Polymers: Crossover Effects at Small Concentrations

open access: yes, 2006
Drag reduction by polymers is bounded between two universal asymptotes, the von-K\'arm\'an log-law of the law and the Maximum Drag Reduction (MDR) asymptote.

Photoionization spectroscopy of excited states of cold cesium dimers

open access: yes, 2010
Photoionization spectroscopy of cold cesium dimers obtained by photoassociation of cold atoms in a magneto-optical trap is reported here. In particular, we report on the observation and on the spectroscopic analysis of all the excited states that have ...

An instrument for quantifying heterogeneous ice nucleation in multiwell plates using infrared emissions to detect freezing [PDF]

open access: yesAtmospheric Measurement Techniques, 2018
Low concentrations of ice-nucleating particles (INPs) are thought to be important for the properties of mixed-phase clouds, but their detection is challenging.

RKKY interaction in the nearly-nested Fermi liquid

open access: yes, 1997
We present the results of analytical evaluation of the indirect RKKY interaction in a layered metal with nearly nested (almost squared) Fermi surface. The final expressions are obtained in closed form as a combination of Bessel functions.
