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…
Holographic correlators of semiclassical states in defect CFTs
George Georgiou, Georgios Linardopoulos, Dimitrios Zoakos
We set up the computation of correlation functions for operators that are dual to semiclassical string states in strongly coupled defect conformal field theories (dCFTs). In the dC…
Holographic correlation functions at finite density and/or finite temperature
George Georgiou, Dimitrios Zoakos
We calculate holographically one and two-point functions of scalar operators at finite density and/or finite temperature. In the case of finite density and zero temperature we argu…
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…
Magnetising the Super Yang-Mills plasma
Alfonso Ballon-Bayona, Jonathan P. Shock, Dimitrios Zoakos
We investigate the thermodynamics of the anisotropic magnetic black brane solution found by D'Hoker and Kraus arXiv:0908.3875. This solution is the gravity dual of a st…
Self-organized PT-symmetry of exciton-polariton condensate in a double-well potential
Panayotis A. Kalozoumis, David Petrosyan
We investigate the dynamics and stationary states of a semiconductor exciton-polariton condensate in a double well potential. We find that upon the population build up of the polar…
On the stability of backgrounds with -deformed factors
Georgios Itsios, Pantelis Panopoulos, Konstantinos Sfetsos +1
We investigate the stability of the non-supersymmetric solutions of type-IIB supergravity having an unwarped factor and -deformed subspaces found in arXiv:1911.12371. Amon…
Giant Gravitons in the Schrodinger holography
George Georgiou, Dimitrios Zoakos
We construct and study new giant graviton configurations in the framework of the non-supersymmetric Schrodinger holography. We confirm in the original Schrodinger spacetime, the pi…
Magnetic catalysis and the chiral condensate in holographic QCD
Alfonso Ballon-Bayona, Jonathan P. Shock, Dimitrios Zoakos
We investigate the effect of a non-zero magnetic field on the chiral condensate using a holographic QCD approach. We extend the model proposed by Iatrakis, Kiritsis and Paredes in…
Giant Gravitons on the Schrodinger pp-wave geometry
George Georgiou, Dimitrios Zoakos
We construct a new giant graviton solution on the recently constructed pp-wave geometry of the non-supersymmetric Schrodinger background. That solution exhibits an intriguing behav…
Coherent population oscillations and an effective spin-exchange interaction in a symmetric polariton mixture
P. A. Kalozoumis, G. M. Nikolopoulos, D. Petrosyan
We study a two-species mixture of exciton-polaritons with self- and cross-interaction nonlinearities in a double well structure, in the presence of relaxation and continuous pumpin…
Duality of bounded and scattering wave systems with local symmetries
I. Kiorpelidis, F. K. Diakonos, G. Theocharis +4
We investigate the spectral properties of a class of hard-wall bounded systems, described by potentials exhibiting domain-wise different local symmetries. Tuning the distance of th…
