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...
