Hamiltonian of a spinning test-particle in curved spacetime

, 2009
Using a Legendre transformation, we compute the unconstrained Hamiltonian of a spinning test-particle in a curved spacetime at linear order in the particle spin.

Hamiltonian Square-Paths

Journal of Combinatorial Theory, Series B, 1996
It is shown that if the minimum degree of a graph \(G\) on \(n\) vertices is at least \((2n-1)/3\) then \(G\) contains a subgraph that can be obtained from a hamiltonian path by adding all edges joining vertices of distance two on the path.

Beyond conventional factorization: Non-Hermitian Hamiltonians with radial oscillator spectrum

, 2009
The eigenvalue problem of the spherically symmetric oscillator Hamiltonian is revisited in the context of canonical raising and lowering operators. The Hamiltonian is then factorized in terms of two not mutually adjoint factorizing operators which, in ...

Fourier Transform of Transfer Matrices of Plane Ising Models

Современные информационные технологии и IT-образование, 2019
This work demonstrates the Fourier transform of the elementary transfer matrix of the generalized two-dimensional Ising model with special boundary conditions with a shift (screw type) with the form of a Hamiltonian covering the classical Ising model ...

On interconnections of infinite-dimensional port-Hamiltonian systems [PDF]

, 2004
Network modeling of complex physical systems leads to a class of nonlinear systems called port-Hamiltonian systems, which are defined with respect to a Dirac structure (a geometric structure which formalizes the power-conserving interconnection structure

Energy Conditions for Hamiltonian and Traceable Graphs

Universal Journal of Mathematics and Applications, 2019
A graph is called Hamiltonian (resp. traceable) if the graph has a Hamiltonian cycle (resp. path), a cycle (resp. path) containing all the vertices of the graph. The energy of a graph is defined as the sum of the absolute values of the eigenvalues of the
