On the Coherent State Path Integral for Linear Systems [PDF]

open access: yes, 2005
We present a computation of the coherent state path integral for a generic linear system using ``functional methods'' (as opposed to discrete time approaches).

Survey of Eight Modern Methods of Hamiltonian Mechanics

open access: yesAxioms, 2021
Here we describe eight new methods, arisen in the last 60 years, to study solutions of a Hamiltonian system with n degrees of freedom. The first six of them are intended for systems with small parameters or without them.

Analytical homoclinic solution of a two dimensional nonlinear system of differential equations [PDF]

open access: yes, 2013
Analytical solution of the homoclinic orbit of a two dimensional system of differential equations that describes the hamiltonian part of the slow flow of a three degree of freedom dissipative system of linear coupled oscillators with an essentially ...

On Linear Hamiltonian Systems [PDF]

open access: yesMATEC Web of Conferences, 2017
In this paper we consider the normalization of quadratic Hamiltonian. We get the new method to find the generating function of the canonical transformation. We obtain the solution of the system of matrix equations to find this transformation. The corresponding Hamiltonian matrix has multiply eigenvalues.

Baxter Equation for the QCD Odderon [PDF]

open access: yes, 1995
The Hamiltonian derived by Bartels, Kwiecinski and Praszalowicz for the study of high-energy QCD in the generalized logarithmic approximation was found to correspond to the Hamiltonian of an integrable $XXX$ spin chain.

Splitting Methods for Semi-Classical Hamiltonian Dynamics of Charge Transfer in Nonlinear Lattices

open access: yesMathematics, 2022
We propose two classes of symplecticity-preserving symmetric splitting methods for semi-classical Hamiltonian dynamics of charge transfer by intrinsic localized modes in nonlinear crystal lattice models.

A necessary and sufficient condition for the stability of linear Hamiltonian systems with periodic coefficients

open access: yes, 2018
Linear Hamiltonian systems with time-dependent coefficients are of importance to nonlinear Hamiltonian systems, accelerator physics, plasma physics, and quantum physics. It is shown that the solution map of a linear Hamiltonian system with time-dependent

Complex planar Hamiltonian systems: Linearization and dynamics

open access: yesDiscrete & Continuous Dynamical Systems, 2021
By now, there are lots of known results on real planar Hamiltonian systems but very few known results on complex planar Hamiltonian systems. The study of the dynamics of complex planar Hamiltonian systems has not only its own theoretical importance but also many practical applications.

Some Oscillation Results for Linear Hamiltonian Systems [PDF]

open access: yesJournal of Applied Mathematics, 2012
The purpose of this paper is to develop a generalized matrix Riccati technique for the selfadjoint matrix Hamiltonian system U′ = A(t)U + B(t)V, V′ = C(t)U − A∗(t)V. By using the standard integral averaging technique and positive functionals, new oscillation and interval oscillation criteria are established for the system.
