Hamiltonian Monte Carlo with Reduced Momentum Flips
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...
On flips of unitary buildings I: Classification of flips
building flip phan involution incidence geometry
2011/1/20
We classify flips of buildings arising from non-degenerate unitary spaces of dimen-sion at least 4 over finite fields of odd characteristic in terms of their action on the underlying vector space. We ...
We study the limiting behavior of the Kahler-Ricci flow on $\mathbb{P}(\mathcal{O}_{\mathbb{P}^n} \oplus \mathcal{O}_{\mathbb{P}^n}(-1)^{\oplus (m+1)})$, assuming the initial metric satisfies the Cal...
Control of the direction and rate of nuclear spin flips in InAs quantum dots using detuned optical pulse trains
nuclear spin flips InAs quantum dots detuned optical pulse trains
2010/4/8
We find that detuning an optical pulse train from electronic transitions in quantum dots controls the direction of nuclear spin flips. The optical pulse train generates electron spins that precess abo...
