The oscillator's model with broken symmetry
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2015 The equations of the oscillator motion are considered. The exact solutions are given in the form of exponents with an additional parameter that characterizes the asymmetry of the oscillations.

An approximating method for the stabilizing solution of the Hamilton-Jacobi equation for integrable systems using Hamiltonian perturbation theory [PDF]
, 2006 In this report, a method for approximating the stabilizing solution of the Hamilton-Jacobi equation for integrable systems is proposed using symplectic geometry and a Hamiltonian perturbation technique.

Simulating Hamiltonian dynamics with a truncated Taylor series. [PDF]
Physical Review Letters, 2014 We describe a simple, efficient method for simulating Hamiltonian dynamics on a quantum computer by approximating the truncated Taylor series of the evolution operator. Our method can simulate the time evolution of a wide variety of physical systems.

Stochastic Gradient Hamiltonian Monte Carlo [PDF]
, 2014 Hamiltonian Monte Carlo (HMC) sampling methods provide a mechanism for defining distant proposals with high acceptance probabilities in a Metropolis-Hastings framework, enabling more efficient exploration of the state space than standard random-walk ...

, 2011 We study a diagonalizable Hamiltonian that is not at first hermitian. Requirement that a measurement shall not change one Hamiltonian eigenstate into another one with a different eigenvalue imposes that an inner product must be defined so as to make the ...

Advanced Functional Materials, EarlyView.Circular photogalvanic effect measurements and first‐principles calculations reveal spin‐splitting states in solution‐processed bournonite films (CuPbSbS3) due to structural and bulk inversion asymmetry. The results provide experimental confirmation of coexisting Rashba and Dresselhaus spin‐splitting states in this non‐centrosymmetric chalcogenide ...

Structure Preserving Model Reduction of Parametric Hamiltonian Systems [PDF]
SIAM Journal on Scientific Computing, 2017 While reduced-order models (ROMs) have been popular for efficiently solving large systems of differential equations, the stability of reduced models over long-time integration presents challenges.

Gauge equivalence in QCD: the Weyl and Coulomb gauges
, 2003 The Weyl-gauge ($A_0^a=0)$ QCD Hamiltonian is unitarily transformed to a representation in which it is expressed entirely in terms of gauge-invariant quark and gluon fields.
