Multi-scale metastable dynamics and the asymptotic stationary distribution of perturbed Markov chains

Volker Betz, Stéphane Le Roux

We consider a simple but important class of metastable discrete time Markov chains, which we call perturbed Markov chains. Basically, we assume that the transition matrices depend…

Collisionless absorption, hot electron generation, and energy scaling in intense laser-target interaction

T. Liseykina, P. Mulser, M. Murakami

Among the various attempts to understand collisionless absorption of intense ultrashort laser pulses a variety of models has been invented to describe the laser beam target interac…

Nuclear structure aspects of spin-independent WIMP scattering off xenon

L. Vietze, P. Klos, J. Menéndez +2

We study the structure factors for spin-independent WIMP scattering off xenon based on state-of-the-art large-scale shell-model calculations, which are shown to yield a good spectr…

From Quarks and Gluons to Hadrons: Chiral Symmetry Breaking in Dynamical QCD

Jens Braun, Leonard Fister, Jan M. Pawlowski +1

We present an analysis of the dynamics of two-flavour QCD in the vacuum. Special attention is payed to the transition from the high energy quark-gluon regime to the low energy regi…

Polyakov-loop suppression of colored states in a quark-meson-diquark plasma

D. Blaschke, A. Dubinin, M. Buballa

A quark-meson-diquark plasma is considered within the PNJL model for dynamical chiral symmetry breaking and restoration in quark matter. Based on a generalized Beth-Uhlenbeck appro…

Local formation of nitrogen-vacancy centers in diamond by swift heavy ions

J. Schwartz, S. Aloni, D. F. Ogletree +6

We exposed nitrogen-implanted diamonds to beams of swift uranium and gold ions (~1 GeV) and find that these irradiations lead directly to the formation of nitrogen vacancy (NV) cen…

Neutrino-pair bremsstrahlung from nucleon- versus nucleon-nucleon scattering

Rishi Sharma, Sonia Bacca, Achim Schwenk

We study the impact of the nucleon- P-wave resonances on neutrino-pair bremsstrahlung. Because of the non-central spin-orbit interaction, these resonances lead to an enhanced co…

Continuum and Three-Nucleon Force Effects on 9Be Energy Levels

Joachim Langhammer, Petr Navratil, Sofia Quaglioni +3

We extend the recently proposed ab initio no-core shell model with continuum to include three-nucleon (3N) interactions beyond the few-body domain. The extended approach allows for…
