Thermoelectric generator in endoreversible approximation: the effect of heat-transfer law under finite physical dimensions constraint
Jasleen Kaur, Ramandeep S. Johal, Michel Feidt
We revisit the optimal performance of a thermoelectric generator within the endoreversible approximation, while imposing a finite physical dimensions constraint (FPDC) in the form…
Spin current transport in hybrid Pt / multifunctional magnetoelectric Ga0.6Fe1.4O3 bilayers
Suvidyakumar Homkar, Elodie Martin, Benjamin Meunier +11
The low power manipulation of magnetization is currently a highly sought-after objective in spintronics. Non ferromagnetic large spin-orbit coupling heavy metal (NM) / ferromagnet…
Strong-coupling emergence of dark states in XX central spin models
Claude Dimo, Alexandre Faribault
It was recently shown that the XX central spin model is integrable in the presence of a magnetic field perpendicular to the plane in which the coupling exists. A large number of it…
Transcritical bifurcation for the conditional distribution of a diffusion process
Michel Benaïm, Nicolas Champagnat, William Oçafrain +1
In this article, we describe a simple class of models of absorbed diffusion processes with parameter, whose conditional law exhibits a transcritical bifurcation. Our proofs are bas…
Observation of degenerate zero-energy topological states at disclinations in an acoustic lattice
Yuanchen Deng, Wladimir A. Benalcazar, Ze-Guo Chen +3
Building upon the bulk-boundary correspondence in topological phases of matter, disclinations have recently been harnessed to trap fractionally quantized density of states (DoS) in…
A new technique for tokamak edge density measurement based on microwave interferometer
Mariia Usoltceva, Stéphane Heuraux, Ildar Khabibullin +1
Novel approach for density measurements at the edge of a hot plasma device is presented - Microwave Interferometer in the Limiter Shadow (MILS). The diagnostic technique is based o…
