Criticality without Temperature in an Ising Spin System
Christos Kakalis, Fotios K. Diakonos
Criticality in the Ising model is conventionally generated by Hamiltonian dynamics and controlled by temperature. Here we show that critical like behavior can emerge in an Ising sy…
Lévy-like flights and fractal geometry of finite point sets
Konstantinos Chalas, F. K. Diakonos, A. S. Kapoyannis
We study Lévy-like and truncated Lévy-like flights with step probability distribution of the form for negative, positive, and zero , focusing on the appearance of fra…
Finite size effects on critical correlations in momentum space
Athanasios Brofas, Fotios K. Diakonos
The search for the QCD critical end point (CEP) is a major objective of contemporary heavy-ion physics, motivating the study of fluctuation observables that are sensitive to critic…
Robustness of perfect transmission resonances to asymmetric perturbation
Ioannis Kiorpelidis, Panayotis Kalozoumis, Georgios Theocharis +3
We investigate the impact of asymmetric perturbations on the perfect transmission resonances (PTRs) of one-dimensional finite periodic systems. With no perturbations, the scatterin…
Transient amplification in stable Floquet media
Ioannis Kiorpelidis, Fotios K. Diakonos, Georgios Theocharis +1
The Mathieu equation occurs naturally in the description of vibrations or in the propagation of waves in media with time-periodic refractive index. It is known to lead to exponenti…
Existence and characterization of edge states in an acoustic trimer Su-Schrieffer-Heeger model
I. Ioannou Sougleridis, A. Anastasiadis, O. Richoux +4
We report on a direct mapping of acoustic slender waveguides to the one dimensional trimer Su- Schrieffer-Heeger model, with neither chiral nor mirror symmetry. Importantly, we can…
