Fermions Tunneling from Higher-Dimensional Reissner-Nordström Black Hole: Semiclassical and Beyond Semiclassical Approximation

open access: yesAdvances in High Energy Physics, 2016
Based on semiclassical tunneling method, we focus on charged fermions tunneling from higher-dimensional Reissner-Nordström black hole. We first simplify the Dirac equation by semiclassical approximation, and then a semiclassical Hamilton-Jacobi equation ...

Optimal Trajectories Associated to a Solution of Contingent Hamilton-Jacobi Equation [PDF]

open access: yesIEEE Conference on Decision and Control, 1987
In this paper we study the existence of optimal trajectories associated with a generalized solution to Hamilton-Jacobi-Bellman equation arising in optimal control. In general, we cannot expect such solutions to be differentiable.

Dynamic programming principle for backward doubly stochastic recursive optimal control problem and sobolev weak solution of the stochastic Hamilton-Jacobi-Bellman equation [PDF]

open access: yesFundamental Research
In this paper, we investigate a backward doubly stochastic recursive optimal control problem wherein the cost function is expressed as the solution to a backward doubly stochastic differential equation.

Spinning black holes with a separable Hamilton–Jacobi equation from a modified Newman–Janis algorithm [PDF]

open access: yesThe European Physical Journal C, 2020
Obtaining solutions of the Einstein field equations describing spinning compact bodies is typically challenging. The Newman–Janis algorithm provides a procedure to obtain rotating spacetimes from a static, spherically symmetric, seed metric.

The Parisi formula is a Hamilton–Jacobi equation in Wasserstein space

open access: yesCanadian Journal of Mathematics - Journal Canadien de Mathematiques, 2021
The Parisi formula is a self-contained description of the infinite-volume limit of the free energy of mean-field spin glass models. We showthat this quantity can be recast as the solution of a Hamilton–Jacobi equation in the Wasserstein space of ...

Hamilton-Jacobi equation for spinning particles near black holes [PDF]

open access: yesPhysical Review D, 2019
A compact stellar-mass object inspiralling onto a massive black hole deviates from geodesic motion due to radiation-reaction forces as well as finite-size effects. Such post-geodesic deviations need to be included with sufficient precision into wave-form

Evaluation of the Feynman Propagator by Means of the Quantum Hamilton-Jacobi Equation

open access: yesQuanta, 2023
It is shown that the complex phase of the Feynman propagator is a solution of the quantum Hamilton–Jacobi equation, namely, it is the quantum Hamilton's principal function (or quantum action).

Extending the Parisi formula along a Hamilton-Jacobi equation [PDF]

open access: yesElectronic Journal of Probability, 2019
We study the free energy of mixed $p$-spin spin glass models enriched with an additional magnetic field given by the canonical Gaussian field associated with a Ruelle probability cascade.

Separability in consistent truncations

open access: yesJournal of High Energy Physics, 2021
The separability of the Hamilton-Jacobi equation has a well-known connection to the existence of Killing vectors and rank-two Killing tensors. This paper combines this connection with the detailed knowledge of the compactification metrics of consistent ...
