چکیده
We consider the dynamics of continuously measured many-body chaotic quantum systems. Focusing on observable state purification, we analytically describe limits strong and weak measurement rate, where in latter case monitoring up to time scales exponentially long numbers particles is required. complement analysis limiting regimes with construction an effective replica theory providing information stability symmetries respective phases. The analytical results are tested by comparison exact numerical simulations for a SYK model.

Localization and Glassy Dynamics Of Many-Body Quantum Systems
When classical systems fail to explore their entire configurational space, intriguing macroscopic phenomena like aging and glass formation may emerge. Also closed quanto-mechanical systems may stop wandering freely around the whole Hilbert space, even if they are initially prepared into a macroscopically large combination of eigenstates. Here, we report numerical evidences that the dynamics of ...
متن کاملProbing quantum many-body dynamics in nuclear systems
Quantum many-body nuclear dynamics is treated at the mean-field level with the time-dependent Hartree-Fock (TDHF) theory. Low-lying and high-lying nuclear vibrations are studied using the linear response theory. The fusion mechanism is also described for light and heavy systems. The latter exhibit fusion hindrance due to quasi-fission. Typical characteristics of quasi-fission, such as contact t...
متن کاملAdiabatic dynamics in open quantum critical many-body systems.
The purpose of this work is to understand the effect of an external environment on the adiabatic dynamics of a quantum critical system. By means of scaling arguments we derive a general expression for the density of excitations produced in the quench as a function of its velocity and of the temperature of the bath. We corroborate the scaling analysis by explicitly solving the case of a one-dime...
