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

Path-integral isomorphic Hamiltonian for including nuclear quantum effects in non-adiabatic dynamics. [PDF]
Journal of Chemical Physics, 2017 We describe a path-integral approach for including nuclear quantum effects in non-adiabatic chemical dynamics simulations. For a general physical system with multiple electronic energy levels, a corresponding isomorphic Hamiltonian is introduced such ...

Discussiones Mathematicae Graph Theory, 2015 For integers k and n with 2 ≤ k ≤ n − 1, a graph G of order n is k-path pancyclic if every path P of order k in G lies on a cycle of every length from k + 1 to n. Thus a 2-path pancyclic graph is edge-pancyclic.

Hamiltonian formalism for path-dependent Lagrangians [PDF]
Physical Review D, 1987 A presymplectic structure for path-dependent Lagrangian systems is set up such that, when applied to ordinary Lagrangians, it yields the familiar Legendre transformation. It is then applied to derive a Hamiltonian formalism and the conserved quantities for those predictive invariant systems whose solutions also satisfy a Fokker-type action principle.

Grafos hamiltonianos en el diseño de viajes
Modelling in Science Education and Learning, 2013 The existence and, if applicable, the location of paths with given properties is a topic in graph theory. One of these problems is to find routes through all points, only once, starting and ending at the same node.

Coherent State Path Integrals in the Weyl Representation [PDF]
, 2006 We construct a representation of the coherent state path integral using the Weyl symbol of the Hamiltonian operator. This representation is very different from the usual path integral forms suggested by Klauder and Skagerstan in \cite{Klau85}, which ...

On mutually independent hamiltonian paths
Applied Mathematics Letters, 2006 Two Hamiltonian paths \(P_1=\langle v_1,v_2,\dots,v_n\rangle\) and \(P_2=\langle u_1,u_2,\dots,u_n\rangle\) of an \(n\)-vertex graph \(G\) are independent if \(u_1=v_1\), \(u_n=v_n\), and \(u_i\neq v_i\) for ...

Decomposing the Complete Graph Into Hamiltonian Paths (Cycles) and 3-Stars
Discussiones Mathematicae Graph Theory, 2020 Let H be a graph. A decomposition of H is a set of edge-disjoint subgraphs of H whose union is H. A Hamiltonian path (respectively, cycle) of H is a path (respectively, cycle) that contains every vertex of H exactly once.

Renormalized Path Integral in Quantum Mechanics [PDF]
, 1996 We obtain direct, finite, descriptions of a renormalized quantum mechanical system with no reference to ultraviolet cutoffs and running coupling constants, in both the Hamiltonian and path integral pictures.
