Hamiltonian Thermodynamics [PDF]
Nelineinaya Dinamika, 2020 It is believed that thermodynamic laws are associated with random processes occurring in the system and, therefore, deterministic mechanical systems cannot be described within the framework of the thermodynamic approach. In this paper, we show that thermodynamics (or, more precisely, a thermodynamically-like description) can be constructed even for ...

Renormalization of Hamiltonians [PDF]
Physical Review D, 1993 A matrix model of an asymptotically free theory with a bound state is solved using a perturbative similarity renormalization group for hamiltonians. An effective hamiltonian with a small width, calculated including the first three terms in the perturbative expansion, is projected on a small set of effective basis states. The resulting small hamiltonian

Torus–Connected Cycles: A Simple and Scalable Topology for Interconnection Networks
International Journal of Applied Mathematics and Computer Science, 2015 Supercomputers are today made up of hundreds of thousands of nodes. The interconnection network is responsible for connecting all these nodes to each other.

An Energy Consistent Discretization of the Nonhydrostatic Equations in Primitive Variables
Journal of Advances in Modeling Earth Systems, 2020 We derive a formulation of the nonhydrostatic equations in spherical geometry with a Lorenz staggered vertical discretization. The combination conserves a discrete energy in exact time integration when coupled with a mimetic horizontal discretization ...

Condensed Forms for Skew-Hamiltonian/Hamiltonian Pencils [PDF]
SIAM Journal on Matrix Analysis and Applications, 2000 Canonical forms and almost-Schur forms for a special class of pencils (real and complex skew-Hamiltonian / Hamiltonian) under \(J\)-congruences are considered in the paper. A necessary and sufficient condition for the existence of a \(J\)-Schur form is also given. The pencils studied occur for example in the theory of optimal control problems.

CoRR, 2015 Approximate Bayesian computation (ABC) is a powerful and elegant framework for performing inference in simulation-based models. However, due to the difficulty in scaling likelihood estimates, ABC remains useful for relatively low-dimensional problems. We introduce Hamiltonian ABC (HABC), a set of likelihood-free algorithms that apply recent advances in

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 purification [PDF]
Journal of Mathematical Physics, 2015 The problem of Hamiltonian purification introduced by Burgarth et al. [Nat. Commun. 5, 5173 (2014)] is formalized and discussed. Specifically, given a set of non-commuting Hamiltonians {h1, …, hm} operating on a d-dimensional quantum system ℋd, the problem consists in identifying a set of commuting Hamiltonians {H1, …, Hm} operating on a larger dE ...
