Shadow Hamiltonians of structure-preserving integrators for Nambu mechanics

Atsushi Horikoshi

Symplectic integrators are widely implemented numerical integrators for Hamiltonian mechanics, which preserve the Hamiltonian structure (symplecticity) of the system. Although the…

Classical Nambu brackets in higher dimensions

Cristel Chandre, Atsushi Horikoshi

We consider n-linear Nambu brackets in dimension N higher than n. Starting from a Hamiltonian system with a Poisson bracket and K Casimir invariants defined in the phase space of d…

Nambu dynamics and its noncanonical Hamiltonian representation in many degrees of freedom systems

Atsushi Horikoshi

Nambu dynamics is a generalized Hamiltonian dynamics of more than two variables, whose time evolutions are given by the Nambu bracket, a generalization of the canonical Poisson bra…

Hidden Nambu mechanics II: Quantum/semiclassical dynamics

Atsushi Horikoshi

Nambu mechanics is a generalized Hamiltonian dynamics characterized by an extended phase space and multiple Hamiltonians. In a previous paper [Prog. Theor. Exp. Phys. 2013, 073A01…

External Source Method for Kubo-Transformed Quantum Correlation Functions

Atsushi Horikoshi

We revisit the external source method for Kubo-transformed quantum correlation functions recently proposed by Krishna and Voth. We derive an exact formula and show that the Krishna…

A Formulation of the Ring Polymer Molecular Dynamics

Atsushi Horikoshi

The exact formulation of the path integral centroid dynamics is extended to include composites of the position and momentum operators. We present the generalized centroid dynamics…
