Ergodicity of one-dimensional systems coupled to the logistic thermostat
Diego Tapias, Alessandro Bravetti, David P. Sanders
We analyze the ergodicity of three one-dimensional Hamiltonian systems, with harmonic, quartic and Mexican-hat potentials, coupled to the logistic thermostat. As criteria for ergod…
Exact Baker-Campbell-Hausdorff formula for the contact Heisenberg algebra
Alessandro Bravetti, Angel Garcia-Chung, Diego Tapias
In this work we introduce the contact Heisenberg algebra which is the restriction of the Jacobi algebra on contact manifolds to the linear and constant functions. We give the exact…
Geometric integrator for simulations in the canonical ensemble
Diego Tapias, David P. Sanders, Alessandro Bravetti
In this work we introduce a geometric integrator for molecular dynamics simulations of physical systems in the canonical ensemble. In particular, we consider the equations arising…
Contact Hamiltonian Mechanics
Alessandro Bravetti, Hans Cruz, Diego Tapias
In this work we introduce contact Hamiltonian mechanics, an extension of symplectic Hamiltonian mechanics, and show that it is a natural candidate for a geometric description of no…
