Thermalization in a nonlinear variant of the discrete nonlinear Schrödinger Equation
Yagmur Kati, Aleksandra Maluckov, Ana Mancic +1
We study the thermalization properties of a fully nonlinear lattice model originally derived from the two-dimensional cubic defocusing nonlinear Schr{ö}dinger equation (NLS) using…
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…
How close Are Integrable and Non-integrable Models: A Parametric Case Study Based on the Salerno Model
Thudiyangal Mithun, Aleksandra Maluckov, Ana Mančić +2
In the present work we revisit the Salerno model as a prototypical system that interpolates between a well-known integrable system (the Ablowitz-Ladik lattice) and an experimentall…
Bend-Free Multiarm Interferometers on Optical Chips
Jovana Petrovic, Aleksandra Maluckov, Nikola Stojanovic
Multiarm interferometers can enhance measurement precision and provide multiparameter capability to the measurement. Their realisation requires multiport beam splitters, which has…
Nonlinear compact localized modes in flux-dressed octagonal-diamond photonic lattice
M. G. Stojanovic, S. Gundogdu, D. Leykam +4
Tuning the values of artificial flux in the two-dimensional octagonal-diamond lattice drives topological phase transitions, including between singular and non-singular flatbands. W…
Nonlinear signatures of Floquet band topology
Aleksandra Maluckov, Ekaterina Smolina, Daniel Leykam +3
We study how the nonlinear propagation dynamics of bulk states may be used to distinguish topological phases of slowly-driven Floquet lattices. First, we show how instabilities of…
