Randomised measurements of a disorder-induced entanglement transition in a neutral atom quantum processor
Apollonas S. Matsoukas-Roubeas, Oscar Scholin, Lucas Sá +5
The development and spread of entanglement in complex quantum systems is central to exploring many-body phenomena out of equilibrium. Measuring entanglement dynamics can shed light…
Dynamics of Loschmidt echoes from operator growth in noisy quantum many-body systems
Takato Yoshimura, Lucas Sá
We study the dynamics of Loschmidt echoes in noisy quantum many-body systems without conservation laws. We first show that the operator Loschmidt echo in noisy unitary dynamics is…
Dissipation- versus Chaos-Induced Relaxation in Non-Markovian Quantum Many-Body Systems
Gabriel Almeida, Pedro Ribeiro, Masudul Haque +1
In interacting quantum many-body systems, relaxation toward equilibrium reflects a competition between internal chaotic dynamics and environmental dissipation. While conventional M…
Lindblad many-body scars
Antonio M. GarcÃa-GarcÃa, Zhongling Lu, Lucas Sá +1
Quantum many-body scars have received much recent attention for being both intriguing non-ergodic states in otherwise quantum chaotic systems and promising candidates to encode qua…
Exactly solvable dissipative dynamics and one-form strong-to-weak spontaneous symmetry breaking in interacting two-dimensional spin systems
Lucas Sá, Benjamin Béri
We study the dissipative dynamics of a class of interacting ``gamma-matrix'' spin models coupled to a Markovian environment. For spins on an arbitrary graph, we construct a Lindbla…
