Sortable elements and Cambrian lattices

Nathan Reading

We show that the Coxeter-sortable elements in a finite Coxeter group W are the minimal congruence-class representatives of a lattice congruence of the weak order on W. We identify…

Low Energy Dynamics in Ultradegenerate QCD Matter

Thomas Schafer, Kai Schwenzer

We study the low energy behavior of QCD Green functions in the limit that the baryon chemical potential is much larger than the QCD scale parameter . We show that there is a…

Search for the Invisible Decay of Neutrons with KamLAND

The KamLAND collaboration

The Kamioka Liquid scintillator Anti-Neutrino Detector (KamLAND) is used in a search for single neutron or two neutron intra-nuclear disappearance that would produce holes in the $…

Pfaffian pairing wave functions in electronic structure quantum Monte Carlo

M. Bajdich, L. Mitas, G. Drobný +2

We investigate the accuracy of trial wave function for quantum Monte Carlo based on pfaffian functional form with singlet and triplet pairing. Using a set of first row atoms and mo…

Understanding Supernova Neutrino Physics using Low-Energy Beta-Beams

N. Jachowicz, G. C. McLaughlin

We show that fitting linear combinations of low-energy beta-beam spectra to supernova-neutrino energy-distributions reconstructs the response of a nuclear target to a supernova flu…

Maximum likelihood estimation of phylogenetic tree and substitution rates via generalized neighbor-joining and the EM algorithm

Asger Hobolth, Ruriko Yoshida

A central task in the study of molecular sequence data from present-day species is the reconstruction of the ancestral relationships. The most established approach to tree reconstr…

Fermionic Quasiparticles in QCD at High Baryon Density

Thomas Schaefer

We study fermionic quasi-particles in QCD at very high baryon density. In the normal quark matter phase unscreened magnetic gluon exchanges lead to non-Fermi liquid behavior. Non-F…
