Chiral transition in a Non-Abelian Quasi-Particle Model with three quark flavours
Eleftherios P. Politis, Antonis Tsapalis, Fotios K. Diakonos
We combine the recently introduced Non-Abelian Quasi-Particle Model (NAQPM) for gluons with an ideal Fermi gas of three quark species with the aim to describe the equation of state…
Continuum Model of Isospectrally Patterned Lattices
Fotis K. Diakonos, P. Schmelcher
Isospectrally patterned lattices (IPL) have recently been shown to exhibit a rich band structure comprising both regimes of localized as well as extended states. The localized stat…
-Continuum limit of bipartite lattices -- The SSH model
Fotios K. Diakonos, P. Schmelcher
We present a continuous non-local model that faithfully replicates the rich topological and spectral features of the Su-Schrieffer-Heeger (SSH) model. Remarkably, our model shares…
Hypercontractivity and factorial moment scaling in the symmetry broken phase
Athanasios Brofas, Manolis Zampetakis, Fotios Diakonos
The search for remnants of the QCD chiral critical point is a central objective of current and future high-energy ion collision experiments. Previous studies suggest that a scaling…
Fast, robust and amplified transfer of topological edge modes on time-varying mechanical chain
I. Brouzos, I. Kiorpelidis, F. K. Diakonos +1
We show that it is possible to successfully, rapidly and robustly transfer a topological vibrational edge mode across a time-varying mechanical chain. The stiffness values of the s…
Wavelet based detection of scaling behaviour in noisy experimental data
Yiannis F. Contoyiannis, Stelios Potirakis, Fotios K. Diakonos
The detection of power-laws in real data is a demanding task for several reasons. The two, more frequently met, being: (i) real data possess noise which affects significantly the p…
Open and closed spin chains as multiprocessor wires: optimal engineering and reachability
N. E. Palaiodimopoulos, I. Brouzos, N. Georgoulea +2
We consider the perfect transfer of a state between arbitrary nodes of one-dimensional spin-1/2 chain with optimally engineered couplings. Motivated by the fact that such a system…
Viscosity of a net-baryon fluid near the QCD critical point
N. G. Antoniou, F. K. Diakonos, A. S. Kapoyannis
In the dynamics of the QCD critical point, the net-baryon fluid, linked to the slow component of the order parameter, relaxes to a 3d Ising system in equilibrium. An analytical stu…
Generalized continuity equations from two-field Schrödinger Lagrangians
Aris G. B. Spourdalakis, George Pappas, Christian V. Morfonios +3
A variational scheme for the derivation of generalized, symmetry-induced continuity equations for Hermitian and non-Hermitian quantum mechanical systems is developed. We introduce…
Domain magnetization approach to the isothermal critical exponent
A. -M. Tsopelakou, G. Margazoglou, Y. F. Contoyiannis +3
We propose a method for calculating the isothermal critical exponent in Ising systems undergoing a second-order phase transition. It is based on the calculation of the mean mag…
symmetry breaking in waveguide arrays with competing loss/gain pairs
P. A. Kalozoumis, C. V. Morfonios, F. K. Diakonos +1
We consider a periodic waveguide array whose unit cell consists of a -symmetric quadrimer with two competing loss/gain parameter pairs which lead to qualitatively dif…
Non-local Lagrangians: a variational approach to non-local conservation laws for wave mechanics
A. G. B. Spourdalakis, G. Pappas, P. A. Kalozoumis +2
We introduce a class of non-local Lagrangians which allow for the variational derivation of non-local conser- vation laws in a self-consistent manner. The formalism developed here…
