Using Space-Filling Curves and Fractals to Reveal Spatial and Temporal Patterns in Neuroimaging Data
Jacek Grela, Zbigniew Drogosz, Jakub Janarek +6
We present a novel method, Fractal Space-Curve Analysis (FSCA), which combines Space-Filling Curve (SFC) mapping for dimensionality reduction with fractal Detrended Fluctuation Ana…
Berezinskii approach to disordered spin systems with asymmetric scattering and application to the quantum boomerang effect
Jakub Janarek, Nicolas Cherroret, Dominique Delande
We extend the Berezinskii diagrammatic technique to one-dimensional disordered spin systems, in which time-reversal invariance is broken due to a spin-orbit coupling term inducing…
Investigating structural and functional aspects of the brain's criticality in stroke
Jakub Janarek, Zbigniew Drogosz, Jacek Grela +2
This paper addresses the question of the brain's critical dynamics after an injury such as a stroke. It is hypothesized that the healthy brain operates near a phase transition (cri…
Many-body quantum boomerang effect
Jakub Janarek, Jakub Zakrzewski, Dominique Delande
We study numerically the impact of many-body interactions on the quantum boomerang effect. We consider various cases: weakly interacting bosons, the Tonks-Girardeau gas, and strong…
Quantum boomerang effect in systems without time reversal symmetry
Jakub Janarek, Benoît Grémaud, Jakub Zakrzewski +1
In an Anderson localized system, a quantum particle with a nonzero initial velocity returns, on average, to its origin. This recently discovered behavior is known as the quantum bo…
Quantum boomerang effect for interacting particles
Jakub Janarek, Dominique Delande, Nicolas Cherroret +1
When a quantum particle is launched with a finite velocity in a disordered potential, it may surprisingly come back to its initial position at long times and remain there forever.…
Discrete disorder models for many-body localization
Jakub Janarek, Dominique Delande, Jakub Zakrzewski
Using exact diagonalization technique, we investigate the many-body localization phenomenon in the 1D Heisenberg chain comparing several disorder models. In particular we consider…
