Observation of topologically protected compact edge states in flux-dressed graphene photonic lattices
Gabriel Cáceres-Aravena, Milica Nedić, Paloma Vildoso +4
Systems with engineered flatband spectra are a postulate of high-capacity transmission links and a candidate for high-temperature superconductivity. However, their operation relies…
Influence of different disorder types on Aharonov-Bohm caging in the diamond chain
Goran Gligorić, Daniel Leykam, Aleksandra Maluckov
The linear diamond chain with fine-tuned effective magnetic flux has a completely flat energy spectrum and compactly-localized eigenmodes, forming an Aharonov-Bohm cage. We study n…
Nonlinear symmetry breaking of Aharonov-Bohm cages
Goran Gligorić, Petra P. Beličev, Daniel Leykam +1
We study the influence of mean field cubic nonlinearity on Aharonov-Bohm caging in a diamond lattice with synthetic magnetic flux. For sufficiently weak nonlinearities the Aharonov…
Nonlinear gap modes and compactons in a lattice model for spin-orbit coupled exciton-polaritons in zigzag chains
Magnus Johansson, Petra P. Beličev, Goran Gligorić +2
We consider a system of generalized coupled Discrete Nonlinear Schrödinger (DNLS) equations, derived as a tight-binding model from the Gross-Pitaevskii-type equations describing a…
Composite localized modes in discretized spin-orbit-coupled Bose-Einstein condensates
Petra P. Beličev, Goran Gligorić, Jovana Petrovic +3
We introduce a discrete model for binary spin-orbit-coupled (SOC) Bose-Einstein condensates (BEC) trapped in a deep one-dimensional optical lattice. Two different types of the coup…
Make Slow Fast -- how to speed up interacting disordered matter
Goran Gligorić, Kristian Rayanov, Sergej Flach
Anderson and dynamical localization have been experimentally observed with ultra-cold atomic matter. Feshbach resonances are used to efficiently control the strength of interaction…
Influence of boundary conditions on quantum escape
Orestis Georgiou, Goran Gligorić, Achilleas Lazarides +3
It has recently been established that quantum statistics can play a crucial role in quantum escape. Here we demonstrate that boundary conditions can be equally important - moreover…
Interactions destroy dynamical localization with strong and weak chaos
G. Gligorić, J. D. Bodyfelt, S. Flach
Bose-Einstein condensates loaded into kicked optical lattices can be treated as quantum kicked rotor systems. Noninteracting rotors show dynamical localization in momentum space. T…
Interface solitons in locally linked two-dimensional lattices
M. D. Petrovic, G. Gligoric, A. Maluckov +2
Existence, stability and dynamics of soliton complexes, centered at the site of a single transverse link connecting two parallel 2D (two-dimensional) lattices, are investigated. Th…
Transition to miscibility in linearly coupled binary dipolar Bose-Einstein condensates
G. Gligoric, A. Maluckov, M. Stepic +2
We investigate effects of dipole-dipole (DD) interactions on immiscibility-miscibility transitions (IMTs) in two-component Bose-Einstein condensates (BECs) trapped in the harmonic-…
Interface solitons in one-dimensional locally-coupled lattice systems
Lj. Hadzievski, G. Gligoric, A. Maluckov +1
Fundamental solitons pinned to the interface between two discrete lattices coupled at a single site are investigated. Serially and parallel-coupled identical chains (\textit{System…
Two-dimensional discrete solitons in dipolar Bose-Einstein condensates
Goran Gligorić, Aleksandra Maluckov, Milutin Stepić +2
We analyze the formation and dynamics of bright unstaggered solitons in the disk-shaped dipolar Bose-Einstein condensate, which features the interplay of contact (collisional) and…
Collapse instability of solitons in the nonpolynomial Schrödinger equation with dipole-dipole interactions
G. Gligoric, A. Maluckov, Lj. Hadzievski +1
A model of the Bose-Einstein condensate (BEC) of dipolar atoms, confined in a combination of a cigar-shaped trap and optical lattice acting in the axial direction, is studied in th…
