Path Integral Monte Carlo Approach to the U(1) Lattice Gauge Theory in (2+1) Dimensions [PDF]

open access: yes, 2002
Path Integral Monte Carlo simulations have been performed for U(1) lattice gauge theory in (2+1) dimensions on anisotropic lattices. We extractthe static quark potential, the string tension and the low-lying "glueball" spectrum.The Euclidean string ...

Hamiltonian Formalism for Space-time Non-commutative Theories [PDF]

open access: yes, 2000
Space-time non-commutative theories are non-local in time. We develop the Hamiltonian formalism for non-local field theories in d space-time dimensions by considering auxiliary d+1 dimensional field theories which are local with respect to the evolution ...

Proper Hamiltonian Paths in Edge-Coloured Multigraphs [PDF]

open access: yesGraphs and Combinatorics, 2011
Given a $c$-edge-coloured multigraph, a proper Hamiltonian path is a path that contains all the vertices of the multigraph such that no two adjacent edges have the same colour. In this work we establish sufficient conditions for an edge-coloured multigraph to guarantee the existence of a proper Hamiltonian path, involving various parameters as the ...

Hamiltonian path, routing, broadcasting algorithms for connected square network graphs

open access: yesEngineering Science and Technology, an International Journal, 2023
Connected Square Network Graphs (CSNG) in the study of Selcuk (2022) and Selcuk and Tankul (2022) is reconsidered in this paper. Although (CSNG) is a 2-dimensional mesh structure, the most important feature of this graph is that it is a hypercube variant.

De-Signing Hamiltonians for Quantum Adiabatic Optimization [PDF]

open access: yesQuantum, 2020
Quantum fluctuations driven by non-stoquastic Hamiltonians have been conjectured to be an important and perhaps essential missing ingredient for achieving a quantum advantage with adiabatic optimization.

Renormalized Path Integral in Quantum Mechanics [PDF]

open access: yes, 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.

A Hofer-Type Norm of Hamiltonian Maps on Regular Poisson Manifold

open access: yesJournal of Applied Mathematics, 2014
We define a Hofer-type norm for the Hamiltonian map on regular Poisson manifold and prove that it is nondegenerate. We show that the L1,∞-norm and the L∞-norm coincide for the Hamiltonian map on closed regular Poisson manifold and give some sufficient ...

Localization of Floer homology of engulfable topological Hamiltonian loop

open access: yes, 2013
Localization of Floer homology is first introduced by Floer \cite{floer:fixed} in the context of Hamiltonian Floer homology. The author employed the notion in the Lagrangian context for the pair $(\phi_H^1(L),L)$ of compact Lagrangian submanifolds in ...

Graphs with many hamiltonian paths

open access: yesInvolve, a Journal of Mathematics
A graph is \emph{hamiltonian-connected} if every pair of vertices can be connected by a hamiltonian path, and it is \emph{hamiltonian} if it contains a hamiltonian cycle. We construct families of non-hamiltonian graphs for which the ratio of pairs of vertices connected by hamiltonian paths to all pairs of vertices approaches 1. We then consider minimal

Triangle-different Hamiltonian paths

open access: yesJournal of Combinatorial Theory, Series B, 2018
Let $G$ be a fixed graph. Two paths of length $n-1$ on $n$ vertices (Hamiltonian paths) are $G$-different if there is a subgraph isomorphic to $G$ in their union. In this paper we prove that the maximal number of pairwise triangle-different Hamiltonian paths is equal to the number of balanced bipartitions of the ground set, answering a question of K ...
