Mechanisms of localization in a finite harmonically confined optical superlattice
A. Katsaris, I. A. Englezos, C. Weitenberg +2
We investigate the impact of harmonic confinement in a finite optical superlattice and reveal the different mechanisms that can lead to the emergence of localized states. The optic…
Long-Range Interacting Particles on a Helix: A Statistical and Correlation Analysis of Equilibrium Configurations
J. M. Dörre, F. K. Diakonos, P. Schmelcher
We provide a statistical and correlational analysis of the spatial and energetic properties of equilibrium configurations of a few-body system of two to eight equally charged class…
Restoring the topological edge states in a finite optical superlattice
A. Katsaris, I. A. Englezos, C. Weitenberg +2
We consider the emergence of edge states in a finite optical lattice and show that the boundaries of the lattice play a decisive role for their location in the corresponding energy…
Topological edge-states of the PT-symmetric Su-Schrieffer-Heeger model: An effective two-state description
A. F. Tzortzakakis, A. Katsaris, N. E. Palaiodimopoulos +4
We consider the non-Hermitian, parity-time (PT) symmetric extensions of the one-dimensional Su-Schrieffer-Heeger (SSH) model in the topological non-trivial configuration. We study…
Spontaneous symmetry breaking in finite systems and anomalous order-parameter correlations
Fotis K. Diakonos, Yiannis F. Contoyiannis, Stelios M. Potirakis
We show that the spontaneous symmetry breaking can be defined also for finite systems based on the properly defined jump probability between the ground states in the 2d and 3d Isin…
Generalized Continuity Equations for Schrödinger and Dirac Equations
A. Katsaris, P. A. Kalozoumis, F. K. Diakonos
The concept of the generalized continuity equation (GCE) was recently introduced in [J. Phys. A: Math. and Theor. {\bf 52}, 1552034 (2019)], and was derived in the context of i…
