Impact ionization processes in a photodriven Mott insulator: influence of phononic dissipation

Paolo Gazzaneo, Tommaso Maria Mazzocchi, Jan Lotze +1

We study a model for photovoltaic energy collection consisting of a Mott insulating layer in presence of acoustic phonons, coupled to two wide-band fermion leads at different chemi…

Correlated Mott insulators in strong electric fields: Role of phonons in heat dissipation

T. M. Mazzocchi, P. Gazzaneo, J. Lotze +1

We study the spectral and transport properties of a Mott insulator driven by a static electric field into a non-equilibrium steady state. For the dissipation, we consider two mecha…

Suppression of effective spin-orbit coupling by thermal fluctuations in spin-orbit coupled antiferromagnets

Jan Lotze, Maria Daghofer

We apply the finite-temperature variational cluster approach to a strongly correlated and spin-orbit coupled model for four electrons (i.e. two holes) in the subshell. We…

An all-electrical torque differential magnetometer operating under ambient conditions

Akashdeep Kamra, Stefan von Hoesslin, Niklas Roschewsky +5

An all-electrical torque differential magnetometry (also known as cantilever magnetometry) setup employing piezoelectric quartz tuning forks is demonstrated. The magnetometer can b…

Sign of inverse spin Hall voltages generated by ferromagnetic resonance and temperature gradients in yttrium iron garnet|platinum bilayers

Michael Schreier, Gerrit E. W. Bauer, Vitaliy Vasyuchka +13

We carried out a concerted effort to determine the absolute sign of the inverse spin Hall effect voltage generated by spin currents injected into a normal metal. We focus on yttriu…

Experimental test of the spin mixing interface conductivity concept

Mathias Weiler, Matthias Althammer, Michael Schreier +11

We perform a quantitative, comparative study of the spin pumping, spin Seebeck and spin Hall magnetoresistance effects, all detected via the inverse spin Hall effect in a series of…
