Catalan numbers for complex reflection groups

Iain Gordon, Stephen Griffeth

We construct (q,t)-Catalan polynomials and q-Fuss-Catalan polynomials for any irreducible complex reflection group W. The two main ingredients in this construction are Rouquier's f…

Colloidal gels assembled via a temporary interfacial scaffold

Eduardo Sanz, Kathryn A. White, Paul S. Clegg +1

The liquid-liquid phase separation of a binary solvent can be arrested by colloidal particles trapped at the interface [K. Stratford et al., Science 309, 5744 (2005)]. We show expe…

Warm gas phase chemistry as possible origin of high HDO/H2O ratios in hot and dense gases: application to inner protoplanetary discs

Wing-Fai Thi, Peter Woitke, Inga Kamp

The origin of Earth oceans is controversial. Earth could have acquired its water either from hydrated silicates (wet Earth scenario) or from comets (dry Earth scenario). [HDO]/[H2O…

The Quantum Phase of Inflation

Arjun Berera, Raghavan Rangarajan

Inflation models can have an early phase of inflation where the evolution of the inflaton is driven by quantum fluctuations before entering the phase driven by the slope of the sca…

First-order phase transitions from poles in asymptotic representations of partition functions

H. Touchette, R. J. Harris, J. Tailleur

Although partition functions of finite-size systems are always analytic, and hence have no poles, they can be expressed in many cases as series containing terms with poles. Here we…
