Pod systems : an equivariant ordinary differential equation approach to dynamical systems on a spatial domain [PDF]

, 1996
We present a class of systems of ordinary differential equations (ODEs), which we call 'pod systems', that offers a new perspective on dynamical systems defined on a spatial domain.

Jarzynski Equality for Driven Quantum Field Theories

Physical Review X, 2018
The fluctuation theorems, and in particular, the Jarzynski equality, are the most important pillars of modern nonequilibrium statistical mechanics.

Superfluid density, Josephson relation and pairing fluctuations in a multi-component fermion superfluid

Scientific Reports, 2021
In this work, a Josephson relation is generalized to a multi-component fermion superfluid. Superfluid density is expressed through a two-particle Green function for pairing states.

Numerical Investigation of Periodic Fluctuations in Energy Efficiency in Centrifugal Pumps at Different Working Points

Energies, 2017
In order to simulate the energy efficiency fluctuation behavior of an industrial centrifugal pump with a six-blade impeller, a full-scale three-dimensional (3D) an unsteady state computational fluid dynamics (CFD) model was used.

Quantum work statistics close to equilibrium

Physical Review Research, 2020
We study the statistics of work, dissipation, and entropy production of a quantum quasi-isothermal process, where the system remains close to thermal equilibrium along the transformation.

QCD critical end point and baryon number fluctuation

He jishu, 2023
One of the main goals of relativistic heavy-ion collision (HIC) is to search for the critical end point (CEP) of quantum chromodynamics (QCD), and distribution of the net-proton number from experimental measurements shows non-monotonic behavior, which ...

P.: Fluctuation theorems: Work is not an observable [PDF]

, 2007
The characteristic function of the work performed by an external time-dependent force on a Hamiltonian quantum system is identified with the time-ordered correlation function of the exponentiated system’s Hamil-tonian.
