NON-PERTURBATIVE APPROACH TO RANDOM WALK IN MARKOVIAN ENVIRONMENT
Random Walk Random environment CLT Gibbs
2015/9/29
The study of random walk in random evolving environment has attracted much attention lately.
The basic idea is that, due to the time mixing properties of the environment, the CLT should hold

Non-Perturbative Prediction of the Ferromagnetic Transition in Repulsive Fermi Gases
Fermi Gases Ferromagnetic Transition
2011/7/21
It is generally believed that a dilute spin-1/2 Fermi gas with repulsive interactions can undergo a ferromagnetic phase transition to a spin-polarized state at a critical gas parameter $(k_{\text F}a)...
Non-perturbative heterogeneous mean-field approach to epidemic spreading in complex networks
Non-perturbative heterogeneous mean-field approach epidemic spreading complex networks
2011/9/9
Since roughly a decade ago, network science has focussed among others on the problem of how the spreading of diseases depends on structural patterns. Here, we contribute to further advance our underst...
Non-perturbative String Theory from Water Waves
Non-perturbative String Theory Water Waves
2010/12/24
We use a combination of a 't Hooft limit and numerical methods to find non-perturbative solutions of exactly solvable string theories, showing that perturbative solutions in different asymptotic regim...
Stokes Phenomena and Non-perturbative Completion in the Multi-cut Two-matrix Models
Stokes Phenomena Non-perturbative Completion
2010/12/24
The Stokes multipliers in the matrix models are invariants in the string-theory moduli space and related to the D-instanton chemical potentials. They not only represent non-perturbative information bu...
Non-perturbative running of the coupling from four flavour lattice QCD with staggered quarks
Non-perturbative running four flavour lattice QCD
2011/1/7
Using the Schr\"odinger functional (SF) with a single staggered fermion field we calculate the SF coupling in four-flavour QCD for a wide range of energies and lattice sizes up to $L/a=16$. Preliminar...

Non-perturbative predictions cold atom Bose gases tunable interactions
2011/1/7
We derive a theoretical description for dilute Bose gases as a loop expansion in terms of composite- eld propagators by rewriting the Lagrangian in terms of auxiliary elds related to the normal and a...

We present an evaluation of the quark mass renormalization factor for Nf=2+1 QCD. The Schroedinger functional scheme is employed as the intermediate scheme to carry out non-perturbative running from t...
On the computation of non-perturbative effective potentials in the string theory landscape -- IIB/F-theory perspective
computation non-perturbative effective potentials theory landscape -- IIB/F-theory perspective
2010/12/16
We discuss a number of issues arising when computing non-perturbative e ects systematically across the string theory landscape. In particular, we cast the study of fairly generic physical properties i...
