Electronic correlations driving Chirality-Induced Spin Selectivity
Jacek Herbrych, Maria Daghofer
We explicitly account for electron-electron interactions when modeling low-dimensional helical organic molecules. We show that competition between various hopping channels, togethe…
Graph-Theoretic Detection of Hilbert Space Fragmentation
A. Rutkowski, M. Mierzejewski, J. Herbrych
Hilbert-space fragmentation provides a mechanism for ergodicity breaking in quantum many-body systems even in the absence of disorder, leading to dynamically disconnected sectors a…
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…
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…
Tunable Hilbert space fragmentation and extended critical regime
Mateusz Lisiecki, Janez BonÄa, 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…
