NoRA: A Tensor Network Ansatz for Volume-Law Entangled Equilibrium States of Highly Connected Hamiltonians
V Bettaque, B Swingle - Quantum, 2024 - quantum-journal.org
Motivated by the ground state structure of quantum models with all-to-all interactions such as
mean-field quantum spin glass models and the Sachdev-Ye-Kitaev (SYK) model, we …

Bardeen-Cooper-Schrieffer interaction as an infinite-range Penson-Kolb pairing mechanism
We demonstrate that the well-known (k↑,− k↓) Bardeen-Cooper-Schrieffer interaction,
when considered in real space, is equivalent to an infinite-range Penson-Kolb pairing …

Interacting particle systems on sparse -random graphs
We consider a general interacting particle system with interactions on a random graph, and
study the large population limit of this system. When the sequence of underlying graphs …

Observed quantum particles system with graphon interaction
In this paper, we consider a system of heterogeneously interacting quantum particles subject
to indirect continuous measurement. The interaction is assumed to be of the mean-field type …

Correlation and combinatorics: causal contextuality and spin systems
AJ Searle - 2024 - ora.ox.ac.uk
Contextuality is a nonclassical feature of quantum systems---exhibited by data that is
produced empirically or theoretically---which in the realm of sheaf theory is characterised by …
