Non-ergodic one-magnon magnetization dynamics of the kagome lattice antiferromagnet
H. Schlüter, J. Schnack, J. Eckseler
The present view of modern physics on non-equilibrium dynamics is that generic systems equilibrate or thermalize under rather general conditions, even closed systems under unitary…

Escaping the Krylov space during finite precision Lanczos
J. Eckseler, M. Pieper, J. Schnack
The Lanczos algorithm, introduced by Cornelius Lanczos, has been known for a long time and is widely used in computational physics. While often employed to approximate extreme eige…

Permanent oscillations and solitary wave behavior in flatband Heisenberg quantum spin systems
J. Eckseler, J. Schnack
Research on the emergence of thermodynamics in closed quantum systems under unitary time evolution arrived at the consensus that generic systems equilibrate under rather general as…
