Global characteristics of all eigenstates of local many-body Hamiltonians: participation ratio and entanglement entropy
Wouter Beugeling, Alexei Andreanov, Masudul Haque
In the spectrum of many-body quantum systems, the low-energy eigenstates were the traditional focus of research. The interest in the statistical properties of the full eigenspectru…
Order Induced by Dilution in Pyrochlore XY Antiferromagnets
A. Andreanov, P. A. McClarty
XY pyrochlore antiferromagnets are well-known to exhibit order-by-disorder through both quantum and thermal selection. In this paper we consider the effect of substituting non-magn…
Avalanches and hysteresis in frustrated superconductors and XY-spin-glasses
Auditya Sharma, Alexei Andreanov, Markus Mueller
We study avalanches along the hysteresis loop of long-range interacting spin-glasses with continuous XY-symmetry - which serves as a toy model of granular superconductors with long…
Incommensurate, helical spin ground states on the Hollandite lattice
S. Mandal, A. Andreanov, Y. Crespo +1
We present a model of classical Heisenberg spins on a Hollandite lattice, which has been developed to describe the magnetic properties of -MnO and similar compounds. The mod…
