On the stress tensor light-ray operator algebra

Grégoire Olivier Mathys, Matthew Thomas Walters, Alexandre Mathieu Frédéric Belin

We study correlation functions involving generalized ANEC operators of the form integral dx-x-n+2T--x -> in four dimensions. We compute two, three, and ...

Temperature dependence of the(pi,0)anomaly in the excitation spectrum of the 2D quantum Heisenberg antiferromagnet

Henrik Moodysson Rønnow, Goran Nilsen, Martin Mourigal

It is well established that in the low-temperature limit, the two-dimensional quantum Heisenberg antiferromagnet on a square lattice (2DQHAFSL) exhibits an anomaly in its spectrum at short-wavelengths on the zone-boundary. In the vicinity of the (pi, 0) po ...

Terminology and concepts for the characterization of in vivo MR spectroscopy methods and MR spectra: Background and experts' consensus recommendations

Cristina Ramona Cudalbu, Bernard Lanz

With a 40-year history of use for in vivo studies, the terminology used to describe the methodology and results of magnetic resonance spectroscopy (MRS) has grown substantially and is not consistent in many aspects. Given the platform offered by this speci ...

Understanding Regioselective Cleavage in Peptide Hydrolysis by a Palladium(II) Aqua Complex: A Theoretical Point of View

Pablo Campomanes Ramos

Hydrolytic: cleavage of the oligopeptides Ace-Ala-Lys-Tyr-Gly similar to Gly-Met-Ala-Ala-Arg-Ala and Ace-Lys-Gly-Gly-Ala-Gly similar to Pro-Met-Ala-Ala-Arg-Gly by Pd(H2O)(4) was theoretically investigated by using molecular dynamics simulations and q ...

First-principles electronic structure study of Ti-PTCDA contacts

Alfredo Pasquarello, Roberto Car

We investigate the interaction of Ti atoms with thin films made of 3,4,9,10 perylenetetracarboxylic dianhydride (PTCDA) molecules by means of self-consistent electronic structure calculations within a generalized gradient approximated density-functional th ...
