Regge pole and K-matrix models for two particle reactions
… reactions near 1 BeV/c are studied using the Kmatrix formalism. It is found that the general features of the experimental data, including the I = 1 peak in the total cross section are reproduced without the assumption of a KN resonance. It is found the agreement with experiment is best for the …

Sampling-based algorithms for dimension reduction
… question, we consider the problem of low-rank matrix approximation: given a matrix A..., one wants to compute a rank-k matrix (where k << min{m, n}) nearest to A in the Frobenius norm (also known as the Hilbert-Schmidt norm). We prove that using a sample of roughly O(k/[epsilon]) rows of A one …

An analysis of pion-nucleon scattering
… waves were parametrized as a coupled channel K-matrix whose elements are polynomials in energy plus an explicit pole term. A complete description of the investigation and the experimental data used are included as is a description of the theoretical models used for interpretation of the results.

Integrability from Chern-Simons theories
… the boundary analogue of a quasi-classical $R$-matrix and classical $r$-matrix; realising $K$-matrices as the vacuum expectation values of Wilson lines in 4d Chern-Simons theory on a $\bbZ_2$ orbifold; deriving the order $\hbar$ contribution to a $K$-matrix in the rational case and verifying …

A Unified Analysis of the B = 2 System
Results are presented for a unified analysis of the reactions pp → pp, πd → πd and πd → pp over the center-of-mass energy interval from pion threshold to approximately 2.4 GeV. These results for πd → pp and πd elastic scattering are superior to previous VPI analyses of these reactions. In …

Aspects of critical spin 1 chains and 2 dimensional symmetry protected topological phases of matter
… using exact diagonalization (ED) and the density matrix renormalization group (DMRG) algorithm. In particular, the bosonization method gives a formula for the evolution of four Tomonaga-Luttinger liquid (TLL) parameters as a function of the lattice parameters. Using the analytic formulae for the …

Algorithms and algorithmic obstacles for probabilistic combinatorial structures
… combinatorial optimization problems: Large Submatrix Selection, Maximum Cut (Max-Cut) of a graph and Matrix Completion. The Large Submatrix Selection problem is to find a k x k submatrix of an n x n matrix with i.i.d. standard Gaussian entries, which has the largest average entry. It was shown …
