Spin squeezing and precision probing with light and samples of atoms in the gaussian approximation

open access: yes, 2004
We consider an ensemble of trapped atoms interacting with a continuous wave laser field. For sufficiently polarized atoms and for a polarized light field, we may approximate the non-classical components of the collective spin angular momentum operator ...

Memory Bounded Open-Loop Planning in Large POMDPs using Thompson Sampling

open access: yes, 2019
State-of-the-art approaches to partially observable planning like POMCP are based on stochastic tree search. While these approaches are computationally efficient, they may still construct search trees of considerable size, which could limit the ...

Effects of Parton Intrinsic Transverse Momentum on Photon Production in Hard-Scattering Processes

open access: yes, 1998
We calculate the photon production cross section arising from the hard scattering of partons in nucleon-nucleon collisions by taking into account the intrinsic parton transverse momentum distribution and the next-to-leading-order contributions.

Stereoselective β‐C‐aryl Glycosylation Through Ni‐Catalyzed Reductive Cross‐Coupling

open access: yesChemistryEurope, Volume 4, Issue 3, March 2026.
A robust Ni‐catalyzed reductive cross‐coupling of glycosyl halides and aryl halides was developed out‐of‐the‐glovebox using air‐stable, bench‐ready Ni(COD)DQ as a source of Ni0. The reaction was applied to a broad substrate scope with excellent β‐stereoselectivity, and the obtained results are supported by mechanistic and density functional theory ...

Convex relaxation of mixture regression with efficient algorithms [PDF]

open access: yes, 2009
We develop a convex relaxation of maximum a posteriori estimation of a mixture of regression models. Although our relaxation involves a semidefinite matrix variable, we reformulate the problem to eliminate the need for general semidefinite programming ...
