Protected Chaos in a Topological Lattice
Advanced Science, EarlyView.Topological and chaotic dynamics are often considered incompatible, with one expected to dominate or disrupt the other. This work reveals that topological localization can persist even under strong chaotic dynamics and, counter‐intuitively, protect chaotic behavior.

Multipartite Entanglement Generation in a Structured Environment
Entropy, 2020 In this paper, we investigate the entanglement generation of n-qubit states in a model consisting of n independent qubits, each coupled to a harmonic oscillator which is in turn coupled to a bath of N additional harmonic oscillators with nearest-neighbor

Dynamics, symmetries, anomaly and vortices in a rotating cosmic string background
Journal of High Energy Physics, 2022 Non-relativistic conformally invariant systems in a rotating cosmic string (conical) spacetime are analyzed at the classical and quantum levels by means of the gravitoelectromagnetic interpretation of the background.

Duality in the quantum harmonic oscillator
Journal of Physics A: Mathematical and General, 2001 Resuming the theme of a previous paper (Szafraniec F H 2001 Math. Nachtr. at press) we show that any abstract creation (or annihilation) operator is in duality with the finite difference one acting in l2. This duality relation is generic and its spatial character allows both agents to be identified within the class of weighted shifts.

Advanced Science, EarlyView.This study reveals quasiparticle dynamics in ZrTe5. Polarization‐dependent measurements show transient reflectivity anisotropy arises from electron relaxation and lattice vibrations. The first dynamical evidence of a temperature‐induced Lifshitz transition is reported.

Deterministic nonlinear phase gates induced by a single qubit
New Journal of Physics, 2018 We propose deterministic realizations of nonlinear phase gates by repeating a finite sequence of non-commuting Rabi interactions between a harmonic oscillator and only a single two-level ancillary qubit.

Transitionless quantum drivings for the harmonic oscillator
, 2009 Two methods to change a quantum harmonic oscillator frequency without transitions in a finite time are described and compared. The first method, a transitionless-tracking algorithm, makes use of a generalized harmonic oscillator and a non-local potential.
