Non-equilibrium magnetization dynamics of ferromagnetically coupled Kondo spins
Andreas Hackl, Stefan Kehrein, Matthias Vojta
An analytical description of non-equilibrium phenomena in interacting quantum systems is rarely possible. Here we present one example where such a description can be achieved, name…
Quasiparticle Nernst effect in stripe-ordered cuprates
Andreas Hackl, Matthias Vojta, Subir Sachdev
Experiments on underdoped cuprate superconductors suggest an intricate relation between the normal-state Nernst effect and stripe order: The Nernst signal appears enhanced near 1/8…
Nonequilibrium Spin Dynamics in the Ferromagnetic Kondo Model
Andreas Hackl, David Roosen, Stefan Kehrein +1
Motivated by recent experiments on molecular quantum dots we investigate the relaxation of pure spin states when coupled to metallic leads. Under suitable conditions these systems…
Nernst effect in the electron-doped cuprates
Andreas Hackl, Subir Sachdev
We calculate the normal state Nernst signal in the cuprates resulting from a reconstruction of the Fermi surface due to spin density wave order. An order parameter consistent with…
