Folding Free Energy Determination of an RNA Three-Way Junction Using Fluctuation Theorems
Entropy, 2022 Nonequilibrium work relations and fluctuation theorems permit us to extract equilibrium information from nonequilibrium measurements. They find application in single-molecule pulling experiments where molecular free energies can be determined from ...

Generalisation of fluctuation-dissipation theorem to systems with absorbing states
New Journal of Physics, 2023 Systems that evolve towards a state from which they cannot depart are common in nature. But the fluctuation-dissipation theorem (FDT), a fundamental result in statistical mechanics, is mainly restricted to systems near-stationarity.

Quantum bounds and fluctuation-dissipation relations
SciPost Physics, 2022 In recent years, there has been intense attention on the constraints posed by quantum mechanics on the dynamics of the correlation at low temperatures, triggered by the postulation and derivation of quantum bounds on the transport coefficients or on ...

Positive- and negative-frequency noise from an ensemble of two-level fluctuators
Physical Review Research, 2021 The analysis of charge noise based on the Bloch-Redfield treatment of an ensemble of dissipative two-level fluctuators generally results in a violation of the fluctuation-dissipation theorem.

Generalized Fluctuation-Dissipation Theorem for Non-equilibrium Spatially Extended Systems
Frontiers in Physics, 2020 The fluctuation-dissipation theorem (FDT) connecting the response of the system to external perturbations with the fluctuations at thermodynamic equilibrium is a central result in statistical physics. There has been effort devoted to extending the FDT in

Thermal Noise in Cubic Optical Cavities
Photonics, 2021 Thermal noise in optical cavities sets a fundamental limit to the frequency instability of ultra-stable lasers. Numata et al. derived three equations based on strain energy and the fluctuation–dissipation theorem to estimate the thermal noise ...

On fluctuating momentum exchange in idealised models of air–sea interaction [PDF]
Nonlinear Processes in Geophysics, 2019 The dynamics of three local models, for momentum transfer at the air–sea interface, is compared. The models differ by whether or not the ocean velocity is included in the shear calculation applied to the ocean and the atmosphere.

On the link between mechanics and thermal properties: mechanothermics
New Journal of Physics, 2023 We report on the theoretical derivation of macroscopic thermal properties (specific heat, thermal conductivity) of an electrically insulating rod connected to two reservoirs, from the linear superposition of its mechanical mode Brownian motions.

A local fluctuation theorem for large systems [PDF]
, 2013 The fluctuation theorem characterizes the distribution of the dissipation in nonequilibrium systems and proves that the average dissipation will be positive.

Fluctuation and dissipation within a deformed holographic model with backreaction
Physics Letters B, 2021 In this work we study the fluctuation and dissipation of a string attached to a brane in a deformed and backreacted AdS-Schwarzschild spacetime. This space is a solution of Einstein-dilaton equations and contains a conformal exponential factor exp(k/r2)
