- Title: Dissipative phase transition in a spatially-correlated bosonic bath
- Authors: Saptarshi Saha and Rangeet Bhattacharyya
- Abstract summary: We show that atoms in a spatially-correlated thermal bath can show both the behavior depending on the temperature.
In this condition, a set of weak symmetries exist, which prevent thermalization.
The system undergoes a symmetry-broken dissipative phase transition of the first order as the temperature rises above zero.

- Abstract: The presence of symmetries in a closed many-body quantum system results in
integrability. For such integrable systems, complete thermalization does not
occur. As a result, the system remains non-ergodic. On the other hand, a set of
non-interacting atoms connected to a regular bosonic bath thermalizes. Here, we
show that such atoms in a spatially-correlated thermal bath can show both the
behavior depending on the temperature. At zero temperature, the bath has a
large correlation length, and hence it acts as a common environment. In this
condition, a set of weak symmetries exist, which prevent thermalization. The
system undergoes a symmetry-broken dissipative phase transition of the first
order as the temperature rises above zero.

Environments in quantum thermodynamics usually take the role of heat baths.
We show that within the same model, the environment can take three different thermodynamic roles.
The exact role of the environment is determined by the strength and structure of the coupling.

We argue that even in fully integrable models, the system observables exhibit thermalization when the system-bath setup is in a typical eigenstate of its Hamiltonian.
Our findings suggest that chaos and nonintegrability are not the sole drivers of thermalization.

The eigenstate thermalization hypothesis (ETH) explains why chaotic quantum many-body systems thermalize internally if the Hamiltonian lacks symmetries.
We adapt the ETH to noncommuting charges by positing a non-Abelian ETH and invoking the approximate microcanonical subspace introduced in quantum thermodynamics.
