Higher-order exceptional point and Landau-Zener Bloch oscillations in driven non-Hermitian photonic Lieb lattices
Shiqiang Xia, Carlo Danieli, Yingying Zhang +6
We propose a scheme to realize parity-time (PT) symmetric photonic Lieb lattices of ribbon shape and complex couplings, thereby demonstrating the higher-order exceptional point (EP…
Heat percolation in many-body flatband localizing systems
I. Vakulchyk, C. Danieli, Alexei Andreanov +1
Translationally invariant finetuned single-particle lattice Hamiltonians host flat bands only. Suitable short-range many-body interactions result in complete suppression of particl…
Compact breathers generator in one-dimensional nonlinear networks
Carlo Danieli, Alexei Andreanov
Nonlinear networks can host spatially compact time periodic solutions called compact breathers. Such solutions can exist accidentally (i.e. for specific nonlinear strength values)…
Many-body localization transition from flatband fine-tuning
Carlo Danieli, Alexei Andreanov, Sergej Flach
Translationally invariant flatband Hamiltonians with interactions lead to a many-body localization transition. Our models are obtained from single particle lattices hosting a mix o…
