The Horizon Order Parameter

We construct a diffeormorphism invariant operator that is sensitive to how far we are from the black hole horizon. Its expectation value blows up on the horizon and it is small away from the horizon. Using this operator, we propose a non-standard effective action that, we argue, captures some of the relevant physics of quantum black holes, including the absence of the horizon at the full quantu...

The Hidden Order of Wikipedia

We examine the procedural side of Wikipedia, the well-known internet encyclopedia. Despite the lack of structure in the underlying wiki technology, users abide by hundreds of rules and follow well-defined processes. Our case study is the Featured Article (FA) process, one of the best established procedures on the site. We analyze the FA process through the theoretical framework of commons gover...

Two-order-parameter GL fits

(cf. Eqn. (3), (4) of Ref. [1]). Phenomenologically, the coupling term can be motivated in the weak coupling limit by the requirement that it should yield a cos(φ1 − φ2) dependence on the phase difference and not change the free energy if two identical superconductors with the same phase are coupled to each other. For small γ and near Tc, it also reproduces the temperature dependence of the cri...

Parameter independent model order reduction

Several recently developed model order reduction methods for fast simulation of large-scale dynamical systems with two or more parameters are reviewed. Besides, an alternative approach for linear parameter system model reduction as well as a more efficient method for nonlinear parameter system model reduction are proposed in this paper. Comparison between different methods from theoretical eleg...
