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…
Role of anisotropic confining potential and elliptical driving in dynamics of a Ge hole qubit
Bashab Dey, John Schliemann
The squeezing of a Ge planar quantum dot enhances the Rabi frequency of electric dipole spin resonance by several orders of magnitude due to a strong Direct Rashba spin-orbit inter…
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…
