Effective Hamiltonian in the Problem of a "Central Spin" Coupled to a Spin Environment
Spin quantum interactive microcosmic spin micro rotation magnetic particles low-energy properties model
2014/12/23
We consider here the problem of a "giant spin", with spin quantum number S≫1, interacting with a set of microscopic spins. Interactions between the microscopic spins are ignored. This model desc...

Hamiltonian Monte Carlo Reduced Momentum Flips Data Analysis Statistics and Probability
2012/5/29
Hamiltonian Monte Carlo (or hybrid Monte Carlo) with partial momentum refreshment explores the state space more slowly than it otherwise would due to the momentum reversals which occur on proposal rej...
