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…
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…
Time-crystalline behavior in an engineered spin chain
Robin Schäfer, Götz S. Uhrig, Joachim Stolze
Time crystals appear when systems display a commensurate spontaneous breaking of the discrete time translational invariance imposed by an external periodic drive. No consensus on t…
Thermodynamics of Adiabatically Loaded Cold Bosons in the Mott Insulating Phase of One-Dimensional Optical Lattices
K. P. Schmidt, A. Reischl, G. S. Uhrig
In this work we give a consistent picture of the thermodynamic properties of bosons in the Mott insulating phase when loaded adiabatically into one-dimensional optical lattices. We…
Temperature in One-Dimensional Bosonic Mott insulators
A. Reischl, K. P. Schmidt, G. S. Uhrig
The Mott insulating phase of a one-dimensional bosonic gas trapped in optical lattices is described by a Bose-Hubbard model. A continuous unitary transformation is used to map this…
Thermodynamic Properties of the Dimerised and Frustrated S=1/2 Chain
Alexander Bühler, Ute Löw, Götz S. Uhrig
By high temperature series expansion, exact diagonalisation and temperature density-matrix renormalisation the magnetic susceptibility and the specific heat of dimeri…
