Information Exchange Fluctuation Theorem Under Coarse-Graining
MathematicsThe fluctuation theorem for information exchange, originally established by Sagawa and Ueda, provides a fundamental framework for understanding the role of correlations in coupled classical stochastic systems.

Fluctuation theorem in rachet system [PDF]
Journal of Physics A: Mathematical and General, 2004 Fluctuation Theorem(FT) has been studied as far from equilibrium theorem, which relates the symmetry of entropy production. To investigate the application of this theorem, especially to biological physics, we consider the FT for tilted rachet system. Under, natural assumption, FT for steady state is derived.

Nonequilibrium identities of granular vibrating beds [PDF]
, 2013 We derive the integral fluctuation theorem around a nonequilibrium stationary state for frictionless and soft core granular particles under an external vibration achieved by a balance between an external vibration and inelastic collisions.

2D Magnetic and Topological Quantum Materials and Devices for Ultralow Power Spintronics
Advanced Functional Materials, EarlyView.2D magnets and topological quantum materials enable ultralow‐power spintronics by combining robust magnetic order with symmetry‐protected, Berry‐curvature‐driven transport. Fundamentals of 2D anisotropy and spin‐orbit‐coupling induced band inversion are linked to scalable growth and vdW stacking.

Fluctuation theorem on a Riemannian manifold
Physical Review ResearchBased on the covariant underdamped and overdamped Langevin equations with Stratonovich coupling to multiplicative noises and the associated Fokker-Planck equations on a Riemannian manifold, we present the first law of stochastic thermodynamics on the ...

Quantum Thermodynamics with Degenerate Eigenstate Coherences
Entropy, 2016 We establish quantum thermodynamics for open quantum systems weakly coupled to their reservoirs when the system exhibits degeneracies. The first and second law of thermodynamics are derived, as well as a finite-time fluctuation theorem for mechanical ...

Work fluctuation theorem for a Brownian particle in a nonconfining potential
Physical Review Research, 2021 Using the Feynman-Kac formula, a work fluctuation theorem for a Brownian particle in a nonconfining potential, e.g., a potential well with finite depth, is derived.

Entanglement fluctuation theorems [PDF]
Physical Review A, 2019 Pure state entanglement transformations have been thought of as irreversible, with reversible transformations generally only possible in the limit of many copies. Here, we show that reversible entanglement transformations do not require processing on the many copy level, but can instead be undertaken on individual systems, provided the amount of ...
