Threatening excursions in large population quasi-stationary birth and death systems. On a question of Antonio Galves

Pierre Collet, Servet Martínez, Sylvie Méléard

We consider time continuous multispecies birth and death processes in a regime of large populations. The jump rates depend on a large scaling parameter K modeling the charge capaci…

Optimization of multisite reactions in complex compartmentalized media

T. V. Mendes, T. Guérin

In complex media, transport and geometric properties deeply influence the kinetics of random encounters between reactants. Here, we consider the situation where a random walker, mo…

Transverse energy-momentum tensor distributions in polarized nucleons

Ho-Yeon Won, Cédric Lorcé

We complete our study of the relativistic spatial distributions of the energy-momentum tensor inside polarized nucleons within the quantum phase-space formalism. In the present wor…

Polaron-driven switching of octupolar order in doped 5d double perovskite

Dario Fiore Mosca, Lorenzo Celiberti, Leonid V. Pourovskii +1

We investigate how doping-induced small polarons impact the low-temperature multipolar orders of the double perovskite BaCaOsO. By computing intersite exchange inter…

Giant orbital magnetoresistance in the antiferromagnet CoO driven by dynamic orbital angular momentum interaction

Christin Schmitt, Sachin Krishnia, Edgar Galindez-Ruales +12

Recent predictions of orders of magnitude larger orbital current effects compared to spin currents have attracted significant interest. However, the full potential of giant orbital…

Entropy Maximization and Weak Gibbsianity of Quasi-Free Fermionic States

Vojkan Jakšić, Claude-Alain Pillet, Anna Szczepanek

In their 1972 study of approach to equilibrium, Lanford and Robinson showed that gauge-invariant quasi-free states of lattice fermions maximize entropy among all translation-invari…
