Noncoplanar orders and quantum disordered states in maple-leaf (anti)ferromagnets
Martin Gembé, Lasse Gresista, Heinz-Jürgen Schmidt +3
A promising route towards the realization of chiral spin liquids is the quantum melting of classically noncoplanar spin states via quantum fluctuations. In the classical realm, suc…
Exotic magnetization curves in classical square-kagomé spin lattices
Heinz-Jürgen Schmidt, Johannes Richter
Classical spin systems with non-coplanar ground states typically exhibit nonlinear magnetization curves characterized by kinks and jumps. Our article briefly summarizes the most im…
The magnetic field does not perform work -- or does it?
Heinz-Jürgen Schmidt, Thomas Bröcker
We investigate the question discussed in the literature as to whether the magnetic field can perform work using two models that describe interacting magnetic dipoles. In the first…
Stochastic thermodynamics of a finite quantum system coupled to a heat bath
Heinz-Jürgen Schmidt, Jürgen Schnack, Jochen Gemmer
We consider a situation where an -level system (NLS) is coupled to a heat bath without being necessarily thermalized. For this situation we derive general Jarzinski-type equatio…
