Generic fast diffusion for a class of non-convex Hamiltonians with two degrees of freedom
fast diffusion non-convex Hamiltonians two degrees of freedom
2015/9/25
In this paper, we study small perturbations of a class of non-convex integrable Hamiltonians with two degrees offreedom, and we prove a result of diffusion for an open and dense set of perturbations, ...
Connecting orbits for families of Tonelli Hamiltonians
families of Tonelli Hamiltonians Dynamical Systems
2011/9/19
Abstract: We investigate the existence of Arnold diffusion-type orbits for systems obtained by iterating in any order the flows of a family of Tonelli Hamiltonians. Our approach is close to the one of...
Creation of Homoclinic Tangencies in Hamiltonians by the Suspension of Poincaré Sections
Hamiltonian vector field Anosov flow elliptic point homoclinic tangency
2011/9/16
Abstract: In this note we show that for any Hamiltonian defined on a symplectic 4-manifold M and any point p in M, there exists a C2-close Hamiltonian whose regular energy surface through p is either ...
Hierarchy of integrable Hamiltonians describing of nonlinear n-wave interaction
nonlinear n-wave Hamiltonians Hierarchy
2011/7/7
In the paper we construct an hierarchy of integrable Hamiltonian systems which describe the variation of n-wave envelopes in nonlinear dielectric medium. The exact solutions for some special Hamiltoni...
Metric operators for non-Hermitian quadratic su(2) Hamiltonians
Metric operators non-Hermitian quadratic su(2) Hamiltonians
2011/3/1
A class of non-Hermitian quadratic su(2) Hamiltonians that ful l an anti-linear symmetry is constructed. If unbroken this anti-linear symmetry leads to a purely real spectrum and the Hamiltonian can b...

2010/11/23
In this paper we study the spectrum of long-range percolation graphs. The underlying geometry is given in terms of a finitely generated amenable group. We prove that the integrated density of states (...
Wigner quantization of some one-dimensional Hamiltonians
Wigner quantization one-dimensional Hamiltonians
2010/11/15
Recently, several papers have been dedicated to the Wigner quantization of different Hamiltonians. In these examples, many interesting mathematical and physical properties have been shown. Among those...
Effective Hamiltonians for Thin Dirichlet Tubes with Varying Cross-Section
Effective Hamiltonians Thin Dirichlet Tubes Cross-Section
2010/11/22
We show how to translate recent results on effective Hamiltonians for quantum systems constrained to a submanifold by a sharply peaked potential to quantum systems on thin Dirichlet tubes. While the s...
Strong and weak semiclassical limits for some rough Hamiltonians
semiclassical limits rough Hamiltonians
2010/11/12
We present several results concerning the semiclassical limit of the time dependent Schr\"odinger equation with potentials whose regularity doesn't guarantee the uniqueness of the underlying classical...
Integrable Henon-Heiles Hamiltonians: a Poisson algebra approach
Integrable Henon-Heiles Hamiltonians Poisson algebra approach
2010/11/19
The three integrable two-dimensional Henon-Heiles systems and their integrable perturbations are revisited. A family of new integrable perturbations is found, and N-dimensional completely integrable ...

2010/11/26
We apply the notion of asymptotic iteration method (AIM) to determine eigenvalues of the
bosonic Hamiltonians that include a wide class of quantum optical models. We consider solutions
of the Hamilt...
The coherent states for a set of quadratic Hamiltonians in the trap regime are constructed.
A matrix technique which allows to identify directly the creation and annihilation operators will be presen...
