Fermi Liquid near a q=0 Charge Quantum Critical Point

Autor: Mayrhofer, R. David, Wölfle, Peter, Chubukov, Andrey V.

We analyze the quasiparticle interaction function (the fully dressed and antisymmetrized interaction between fermions) for a two-dimensional Fermi liquid at zero temperature close to a q=0 charge quantum critical point (QCP) in the $s-$wave channel (

Nonanalytic Corrections to the Landau Diamagnetic Susceptibility

Autor: Mayrhofer, R. David, Chubukov, Andrey V.

We analyze potential non-analytic terms in the Landau diamagnetic susceptibility, $\chi_{dia}$, at a finite temperature $T$ and/or in-plane magnetic field $H$ in a two-dimensional (2D) Fermi liquid. To do this, we express the diamagnetic susceptibili

Stochastic Thermodynamic Cycles of a Mesoscopic Thermoelectric Engine

Autor: Mayrhofer, R David, Elouard, Cyril, Splettstoesser, Janine, Jordan, Andrew N

Publikováno v: Phys. Rev. B 103, 075404 (2021)

We analyze a steady-state thermoelectric engine, whose working substance consists of two capacitively coupled quantum dots. One dot is tunnel-coupled to a hot reservoir serving as a heat source, the other one to two electrically biased reservoirs at

A neutron scattering measurement of crystalline-electric fields in magnesium rare-earth selenide spinels

Autor: Reig-i-Plessis, D., Cote, A., van Geldern, S., Mayrhofer, R. D., Aczel, A. A., MacDougall, G. J.

Publikováno v: Phys. Rev. Materials 3, 114408 (2019)

The symmetry of local moments plays a defining role in the nature of exotic grounds states stabilized in frustrated magnetic materials. We present inelastic neutron scattering (INS) measurements of the crystal electric field (CEF) excitations in the
