Dynamical mean-field theory for dense spin systems at finite temperature
Przemysław Bieniek, Timo Gräßer, Götz S. Uhrig
In recent years, a method for computing spin dynamics at infinite temperature (spinDMFT) was developed. It utilizes the ideas of dynamical mean-field theory for fermions: single-si…
First-principles simulation of spin diffusion in static solids using dynamic mean-field theory
Timo Gräßer, Götz S. Uhrig, Matthias Ernst
The dynamics of disordered nuclear spin ensembles are the subject of nuclear magnetic resonance studies. Due to the through-space long-range dipolar interaction generically many sp…
Microscopic understanding of NMR signals by dynamic mean-field theory for spins
Timo Gräßer, Thomas Hahn, Götz S. Uhrig
A recently developed dynamic mean-field theory for disordered spins (spinDMFT) is shown to capture the spin dynamics of nuclear spins very well. The key quantities are the spin aut…
Understanding the dynamics of randomly positioned dipolar spin ensembles
Timo Gräßer, Kristine Rezai, Alexander O. Sushkov +1
Dipolar spin ensembles with random spin positions attract much attention currently because they help to understand decoherence as it occurs in solid state quantum bits in contact w…
Truncated Wigner approximation for the bosonic model of large spin baths
Mohsen Yarmohammadi, Katrin Bolsmann, Yvonne Ribbeheger +2
The central spin model has a wide applicability, it is ideally suited to describe a small quantum system, for instance a quantum bit, in contact to a bath of spins, e.g., nuclear s…
Dynamic mean-field theory for dense spin systems at infinite temperature
Timo Gräßer, Philip Bleicker, Dag-Björn Hering +2
A dynamic mean-field theory for spin ensembles (spinDMFT) at infinite temperatures on arbitrary lattices is established. The approach is introduced for an isotropic Heisenberg mode…
