Almost compact moving breathers with fine-tuned discrete time quantum walks
I. Vakulchyk, M. V. Fistul, Y. Zolotaryuk +1
Discrete time quantum walks are unitary maps defined on the Hilbert space of coupled two-level systems. We study the dynamics of excitations in a nonlinear discrete time quantum wa…
Universal Nonlinear Disordered Wave Packet Subdiffusion: 12 Decades
Ihor Vakulchyk, Mikhail V. Fistul, Sergej Flach
We use a novel unitary map toolbox -- discrete time quantum walks originally designed for quantum computing -- to implement ultrafast computer simulations of extremely slow dynamic…
Valley Hall Transport of Photon-Dressed Quasiparticles in 2D Dirac Semiconductors
V. M. Kovalev, Wang-Kong Tse, M. V. Fistul +1
We present a theory of the photovoltaic valley-dependent Hall effect in a two-dimensional Dirac semiconductor subject to an intense near-resonant electromagnetic field. Our theory…
Circuit Quantum Electrodynamics of Granular Aluminum Resonators
N. Maleeva, L. Grünhaupt, T. Klein +12
The introduction of crystalline defects or dopants can give rise to so-called "dirty superconductors", characterized by reduced coherence length and quasiparticle mean free path. I…
Resonant frequencies and spatial correlations in frustrated arrays of Josephson type nonlinear oscillators
A. Andreanov, M. V. Fistul
We present a theoretical study of resonant frequencies and spatial correlations of Josephson phases in frustrated arrays of Josephson junctions. Two types of one-dimensional arrays…
