Analytic rogue wave solutions for a generalized fourth‐order Boussinesq equation in fluid mechanics

open access: yesMathematical methods in the applied sciences, 2018
A bilinear transformation method is proposed to find the rogue wave solutions for a generalized fourth‐order Boussinesq equation, which describes the wave motion in fluid mechanics.

Stability of schooling patterns of a fish pair swimming against a flow

open access: yesFlow, 2023
Fish often swim in crystallized group formations (schooling) and orient themselves against the incoming flow (rheotaxis). At the intersection of these two phenomena, we investigate the emergence of unique schooling patterns through passive hydrodynamic ...

Analytic structure of the S-matrix for singular quantum mechanics [PDF]

open access: yes, 2015
The analytic structure of the S-matrix of singular quantum mechanics is examined within a multichannel framework, with primary focus on its dependence with respect to a parameter (Ω) that determines the boundary conditions.

A critique of Ontological Pluralism: the case for Quantum Mechanics

open access: yesRevista Colombiana de Filosofía de la Ciencia, 2016
Scientifically speaking, quantum mechanics (QM) is the most successful theory ever made. Philosophically speaking, however, it is the most controversial theory.

Van der Waals interactions: Corrections from radiation in fluids

open access: yesAIP Advances, 2013
We consider induced van der Waals interactions with corrections due to radiation in fluids consisting of polarizable hard spheres. The fluctuating polarizations are quantized while the positions of particles are treated classically.

Non-equilibrium statistical mechanics: from a paradigmatic model to biological transport [PDF]

open access: yes, 2011
Unlike equilibrium statistical mechanics, with its well-established foundations, a similar widely accepted framework for non-equilibrium statistical mechanics (NESM) remains elusive. Here, we review some of the many recent activities on NESM, focusing on

Hidden Symmetry from Supersymmetry in One-Dimensional Quantum Mechanics [PDF]

open access: yes, 2009
When several inequivalent supercharges form a closed superalgebra in Quantum Mechanics it entails the appearance of hidden symmetries of a Super-Hamiltonian. We examine this problem in one-dimensional QM for the case of periodic potentials and potentials

Statistical mechanics of temporal association in neural networks with transmission delays [PDF]

open access: yes, 1991
We study the representation of static patterns and temporal sequences in neural networks with signal delays and a stochastic parallel dynamics. For a wide class of delay distributions, the asymptotic network behavior can be described by a generalized ...

Leonhard Euler's “principle of mechanics” (an essay on the foundations of the equations of motion)

open access: yesRevista Brasileira de Ensino de Física
Leonhard Euler derived equations of motion for both (in modern terminology) point mass mechanics and analytic mechanics. In order to derive the equations, some dynamic premise has to be introduced; this is the “principle of mechanics”.

A Soluble Model for Scattering and Decay in Quaternionic Quantum Mechanics I: Decay

open access: yes, 1993
The Lee-Friedrichs model has been very useful in the study of decay-scattering systems in the framework of complex quantum mechanics. Since it is exactly soluble, the analytic structure of the amplitudes can be explicitly studied.
