Generalizing measurement-induced phase transitions to information exchange symmetry breaking
Shane P. Kelly, Jamir Marino
In this work we investigate the conditions for quantum back action to result in a phase transition in the information dynamics of a monitored system. We introduce a framework that…
Dynamics of quantum discommensurations in the Frenkel-Kontorova chain
Oksana Chelpanova, Shane P. Kelly, Ferdinand Schmidt-Kaler +2
The ability for real-time control of topological defects can open up prospects for dynamical manipulation of macroscopic properties of solids. A sub-category of these defects, form…
Markovian to non-Markovian phase transition in the operator dynamics of a mobile impurity
Dominic Gribben, Jamir Marino, Shane P. Kelly
We study a random unitary circuit model of an impurity moving through a chaotic medium. The exchange of information between the medium and impurity is controlled by varying the vel…
Entanglement transitions induced by quantum-data collection
Shane P. Kelly, Jamir Marino
We present an entanglement transition in an array of qubits, induced by the transfer of quantum information from a system to a quantum computer. This quantum-data collection is an…
Thermalization of non-Fermi-liquid electron-phonon systems: Hydrodynamic relaxation of the Yukawa-Sachdev-Ye-Kitaev model
Hossein Hosseinabadi, Shane P. Kelly, Jörg Schmalian +1
We study thermalization dynamics in a fermion-phonon variant of the Sachdev-Ye-Kitaev model coupled to an external cold thermal bath of harmonic oscillators. We find that quantum c…
Injection and nucleation of topological defects in the quench dynamics of the Frenkel-Kontorova model
Oksana Chelpanova, Shane P. Kelly, Giovanna Morigi +2
Topological defects have strong impact on both elastic and inelastic properties of materials. In this article, we investigate the possibility to controllably inject topological def…
Scrambling Transition in a Radiative Random Unitary Circuit
Zack Weinstein, Shane P. Kelly, Jamir Marino +1
We study quantum information scrambling in a random unitary circuit that exchanges qubits with an environment at a rate . As a result, initially localized quantum information no…
Crafting the dynamical structure of synchronization by harnessing bosonic multilevel cavity QED
Riccardo J. Valencia-Tortora, Shane P. Kelly, Tobias Donner +3
Many-body cavity QED experiments are established platforms to tailor and control the collective responses of ensembles of atoms, interacting through one or more common photonic mod…
Coherence requirements for quantum communication from hybrid circuit dynamics
Shane P. Kelly, Ulrich Poschinger, Ferdinand Schmidt-Kaler +2
The coherent superposition of quantum states is an important resource for quantum information processing which distinguishes quantum dynamics and information from their classical c…
Resonant light enhances phase coherence in a cavity QED simulator of fermionic superfluidity
Shane P. Kelly, James K. Thompson, Ana Maria Rey +1
Cavity QED experiments are natural hosts for non-equilibrium phases of matter supported by photon-mediated interactions. In this work, we consider a cavity QED simulation of the BC…
Quantum memory at an eigenstate phase transition in a weakly chaotic model
M. R. Lambert, Shan-Wen Tsai, Shane P. Kelly
We study a fully connected quantum spin model resonantly coupled to a small environment of non-interacting spins, and investigate how initial state properties are remembered at lon…
Zeno crossovers in the entanglement speed of spin chains with noisy impurities
Abhijit P. Chaudhari, Shane P. Kelly, Riccardo J. Valencia-Tortora +1
We use a noisy signal with finite correlation time to drive a spin (dissipative impurity) in the quantum XY spin chain and calculate the dynamics of entanglement entropy of a bipar…

The phenomenon of localization usually happens due to the existence of disorder in a medium. Nevertheless, certain quantum systems allow dynamical localization solely due to the na…
