Thermodynamical Relations in Function Space
T. Koide, T. Kodama
We formulate thermodynamical relations based on the field degrees of freedom by introducing a work induced by the volume change in the function space, in addition to the usual work…
Functional Ideal Hydrodynamics incorporating Quantum-Field Theoretical Fluctuation
T. Koide, T. Kodama
We propose new ideal hydrodynamics in the function space which describes a fluid composed of the 1+1 dimensional real scalar field in the framework of the stochastic variational me…
Possible Enhancements of Collective Flow Anisotropy Induced by Uncertainty Relation for Fluid Element
G. G. Matos, T. Koide, T. Kodama
In the stochastic formulation of viscous hydrodynamics, the velocity of a fluid element fluctuates satisfying a similar relation to the quantum-mechanical uncertainty relation. Usi…
Perturbative expansion of irreversible works in symmetric and asymmetric processes
T. Koide
The systematic expansion method of the solution of the Fokker-Planck equation is developed by generalizing the formulation proposed in [J. Phys. A50, 325001 (2017)]. Using this met…
Poisson bracket operator
T. Koide
We introduce the Poisson bracket operator which is an alternative quantum counterpart of the Poisson bracket. This operator is defined using the operator derivative formulated in q…
Viscous control of minimum uncertainty state in hydrodynamics
T. Koide
A minimum uncertainty state for position and momentum of a fluid element is obtained. We consider a general fluid described by the Navier-Stokes-Korteweg (NSK) equation, which repr…
