Doping antiferromagnet in one-dimension
J. Prokopczyk, J. Herbrych
Antiferromagnetic ground states, when doped, give rise to rich and complex phenomena, prompting detailed investigations in various spin systems. Here, we study the effect of doping…
Boundary-driven magnetization transport in the spin- XXZ chain: Role of the system-bath coupling strength and timescales
Mariel Kempa, Markus Kraft, Sourav Nandy +4
Understanding the transport properties of quantum many-body systems is a central challenge in condensed matter and statistical physics. Theoretical studies usually rely on two main…
Tunable Hilbert space fragmentation and extended critical regime
Mateusz Lisiecki, Janez Bonča, Marcin Mierzejewski +2
Systems exhibiting the Hilbert-space fragmentation are nonergodic, and their Hamiltonians decompose into exponentially many blocks in the computational basis. In many cases, these…
Finding local integrals of motion in quantum lattice models in the thermodynamic limit
J. Pawlowski, J. Herbrych, M. Mierzejewski
Local integrals of motion (LIOMs) play a key role in understanding the long-time properties of closed macroscopic systems. They were found for selected integrable systems via compl…
Spin and energy diffusion vs. subdiffusion in disordered spin chains
J. Herbrych, P. Prelovšek
While the high-temperature spin diffusion in spin chains with random local fields has been the subject of numerous studies concerning the phenomenon of many-body localization (MBL)…
Magnon damping and mode softening in quantum double-exchange ferromagnets
A. Moreo, E. Dagotto, G. Alvarez +3
We present a comprehensive analysis of the magnetic excitations and electronic properties of fully quantum double-exchange ferromagnets, i.e., systems where ferromagnetic ordering…
