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,…
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…
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…
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…
