Path integration for velocity-dependent potentials [PDF]

Communications in Mathematical Physics, 1982
We extent the prodistribution definition of path integrals to include Lagrangians with velocity-dependent potentials. We use Cameron-Martin transformations to evaluate a large part of a path integral exactly and give techniques for evaluating the remaining terms of the semi-classical expansion of the path integral. The Fredholm determinants, associated

Scalar transport in compressible flow

, 1996
Transport of scalar fields in compressible flow is investigated. The effective equations governing the transport at scales large compared to those of the advecting flow are derived by using multi-scale techniques.

Exactly Integrable Dynamics of Interface between Ideal Fluid and Light Viscous Fluid

, 2004
It is shown that dynamics of the interface between ideal fluid and light viscous fluid is exactly integrable in the approximation of small surface slopes for two-dimensional flow.

Influence of Applied Potential on Wall-Bounded Water Flow

International Journal of Electrochemical Science, 2015
Measured potential dependences of flow velocities of aqueous hexafluorophosphate, perchlorate and chloride solutions bring to view velocity maxima, which are near the potentials of minima in earlier reported potential dependences of drag force.

Collision of One-Dimensional Nonlinear Chains

, 2002
We investigate one-dimensional collisions of unharmonic chains and a rigid wall. We find that the coefficient of restitution (COR) is strongly dependent on the velocity of colliding chains and has a minimum value at a certain velocity.

Explaining the subpulse drift velocity of pulsar magnetosphere within the space-charge limited flow model [PDF]

, 2014
We try to explain the subpulse drift phenomena adopting the space-charge limited flow (SCLF) model and comparing the plasma drift velocity in the inner region of pulsar magnetospheres with the observed velocity of drifting subpulses.

Electron dynamics in crystalline semiconductors

, 2012
Electron dynamics in crystalline semiconductors is described by distinguishing between an instantaneous velocity related to electron's momentum and an average velocity related to its quasi-momentum in a periodic potential.

Wave loadings on a vertical cylinder due to heave motion

International Journal of Mathematics and Mathematical Sciences, 1995
Wave forces and moments due to scattering and radiation for a vertical circular cylinder heaving in water of finite depth are derived analytically. These are derived from the total velocity potential which can be decomposed as two velocity potentials ...

Velocity-force characteristics of an interface driven through a periodic potential

, 2002
We study the creep dynamics of a two-dimensional interface driven through a periodic potential using dynamical renormalization group methods. We find that the nature of weak-drive transport depends qualitatively on whether the temperature $T$ is above or

A Two-Loop Test of M(atrix) Theory [PDF]

, 1997
We consider the scattering of two Dirichlet zero-branes in M(atrix) theory. Using the formulation of M(atrix) theory in terms of ten-dimensional super Yang-Mills theory dimensionally reduced to $(0+1)$-dimensions, we obtain the effective (velocity ...
