Compact localized currents in flat bands with broken time-reversal symmetry
Rohit Kishan Ray, Carlo Danieli, Alexei Andreanov +1
We develop a systematic framework for constructing all-bands-flat (ABF) lattice Hamiltonians that explicitly break time-reversal symmetry (TRS). By threading magnetic flux through…
Flat band fine-tuning and its photonic applications
Carlo Danieli, Alexei Andreanov, Daniel Leykam +1
Flat bands - single-particle energy bands - in tight-binding networks have attracted attention due to the presence of macroscopic degeneracies and their extreme sensitivity to pert…
Dynamical chaos in the integrable Toda chain induced by time discretization
Carlo Danieli, Emil A. Yuzbashyan, Boris L. Altshuler +2
We use the Toda chain model to demonstrate that numerical simulation of integrable Hamiltonian dynamics using time discretization destroys integrability and induces dynamical chaos…
Unconventional delocalization in a family of 3D Lieb lattices
Jie Liu, Carlo Danieli, Jianxin Zhong +1
Uncorrelated disorder in generalized 3D Lieb models gives rise to the existence of bounded mobility edges, destroys the macroscopic degeneracy of the flat bands and breaks their co…
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…
