State-dependent mobility edge in kinetically constrained models
Manthan Badbaria, Nicola Pancotti, Rajeev Singh +2
In this work, we show that the kinetically constrained quantum East model lies between a quantum scarred and a many-body localized system featuring an unconventional type of mobili…
Boundary Time Crystals as AC sensors: enhancements and constraints
Dominic Gribben, Anna Sanpera, Rosario Fazio +2
We investigate the use of a boundary time crystals (BTCs) as quantum sensors of AC fields. Boundary time crystals are non-equilibrium phases of matter in contact to an environment,…
Zeno physics of the Ising chain with symmetry-breaking boundary dephasing
Umar Javed, Riccardo J. Valencia-Tortora, Jamir Marino +2
In few-qubit systems, the quantum Zeno effect arises when measurement occurs sufficiently frequently that the spins are unable to relax between measurements. This can compete with…
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…
Quantum-to-classical crossover in the spin glass dynamics of cavity QED simulators
Hossein Hosseinabadi, Darrick E. Chang, Jamir Marino
By solving the quench dynamics of a frustrated many-body spin-boson problem, we investigate the role of spin size on the dynamical formation of spin glass order. In particular, we…
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…
Orthogonality catastrophe beyond bosonization from post-selection
Martino Stefanini, Jamir Marino
We show that the dynamics induced by post-selected measurements can serve as a controlled route to access physical processes beyond the boundaries of Tomonaga-Luttinger liquid phys…
Dynamics of inhomogeneous spin ensembles with all-to-all interactions: breaking permutational invariance
Fernando Iemini, Darrick Chang, Jamir Marino
We investigate the consequences of introducing non-uniform initial conditions in the dynamics of spin ensembles characterized by all-to-all interactions. Specifically, our study in…
Rydberg platform for non-ergodic chiral quantum dynamics
Riccardo J. Valencia-Tortora, Nicola Pancotti, Michael Fleischhauer +2
We propose a mechanism for engineering chiral interactions in Rydberg atoms via a directional antiblockade condition, where an atom can change its state only if an atom to its righ…
