Consecutive-gap ratio distribution for crossover ensembles
Gerson C. Duarte-Filho, Julian Siegl, John Schliemann +1
The study of spectrum statistics, such as the consecutive-gap ratio distribution, has revealed many interesting properties of many-body complex systems. Here we propose a two-param…
From Thermalization to Multifractality: Spin-Spin Correlation in Disordered -Invariant 1D Heisenberg Spin Chains
Debasmita Giri, Julian Siegl, John Schliemann
We investigate spin correlations in one-dimensional -invariant Heisenberg chains with exchange disorder for spin lengths and . In the weak-disorder regime, the…
Friedel oscillations and chiral superconductivity in monolayer NbSe
Julian Siegl, Anton Bleibaum, Wen Wan +5
In 1965 Kohn and Luttinger proposed a genuine electronic mechanism for superconductivity. Despite the bare electrostatic interaction between two electrons being repulsive, in a met…
Hyperplane-Symmetric Static Einstein-Dirac Spacetime
John Schliemann, Tim Sonnleitner
We derive the general solution to the coupled Einstein and Dirac field equations in static and hyperplane-symmetric spacetime of arbitrary dimension including a cosmological consta…
