Measuring the convergence of Monte Carlo free energy calculations (2009)
Hahn, Aljoscha Maria, Then, Holger
A nice property of Bennett's acceptance ratio method is that each free energy estimate readily yields an estimate of the asymptotic mean square error. Assuming convergence, it is easy to specify the...
A characteristic of Bennett's acceptance ratio method (2009)
Hahn, Aljoscha Maria, Then, Holger
A powerful and well-established tool for free-energy estimation is Bennett's acceptance ratio method. Central properties of this estimator, which employs samples of work values of a forward and its...
Computing the optimal protocol for finite-time processes in stochastic thermodynamics (2007)
Asking for the optimal protocol of an external control parameter that minimizes the mean work required to drive a nano-scale system from one equilibrium state to another in finite time, Schmiedl and...
astro-ph/0612308 CMB Alignment in Multi-Connected Universes (2006)
Ralf Aurich, Sven Lustig, Frank Steiner, Holger Then
Abstract. The low multipoles of the cosmic microwave background (CMB) anisotropy possess some strange properties like the alignment of the quadrupole and the octopole, and the extreme planarity or...
Hyperbolic Universes with a Horned Topology and the CMB Anisotropy (2004)
Aurich, Ralf, Lustig, Sven, Steiner, Frank, Then, Holger
We analyse the anisotropy of the cosmic microwave background (CMB) in hyperbolic universes possessing a non-trivial topology with a fundamental cell having an infinitely long horn. The aim of this...
