NON-PERTURBATIVE APPROACH TO RANDOM WALK IN MARKOVIAN ENVIRONMENT
Random Walk Random environment CLT Gibbs
font style='font-size:12px;'>
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
font style='font-size:12px;'>
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)...

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...

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...

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...

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...
