Recent advances in experimental techniques allow one to measure and control systems at
the level of single molecules and atoms. Here gaining information about fluctuating …

Work extraction from the Gibbs ensemble by a cyclic operation is impossible, as represented
by the second law of thermodynamics. On the other hand, the eigenstate thermalization …

The canonical ensemble plays a crucial role in statistical mechanics in and out of
equilibrium. For example, the standard derivation of the fluctuation theorem relies on the …

Optical computing is emerging as a promising platform for energy-efficient, high-throughput
hardware in deep learning. A key challenge lies in the realization of optical matrix-vector …

We examine the relationship between the second law of thermodynamics and the energy
eigenstates of quantum many-body systems that undergo cyclic unitary evolution. Using a …

We consider conditions under which an isolated quantum system approaches a
microcanonical equilibrium state. A key component is the eigenstate thermalization …

Fluctuation theorems are cornerstones of modern statistical mechanics and their standard
derivations routinely rely on the crucial assumption of a canonical equilibrium state. Yet …

Inspired by Niels Bohr's adoption of the Taijitu symbol of Yin Yang in his quantum
complementarity worldview, this original paper introduces Yin Yang cosmology as an …
