E. Bogomolny 1, J. P. Keating 2 Journal of Physics A General Physics 46 (2013) 305203 We illustrate a general method for calculating spectral statistics that combines the universal (Random Matrix Theory limit) and the non-universal (trace-formula-related) contributions by giving a heuristic derivation of the three-point correlation function for the zeros of the Riemann zeta function. The main idea […]

Pierre Ronceray 1, 2, Peter Harrowell 3 Physical Review E 87 (2013) 052313 The ordering transitions of a 2D lattice liquid characterized by a single favoured local structure (FLS) are studied using Monte Carlo simulations. All eight distinct geometries for the FLS are considered and we find a variety of ordering transitions – first order, continuous and multi-step transitions. Using

Guillaume Roux1, Anna Minguzzi2, Tommaso Roscilde3 New J. Phys. 15, 055003 (2013) We study the dynamic structure factor of a one-dimensional Bose gas confined in an optical lattice and modeled by the Bose-Hubbard Hamiltonian, using a variety of numerical and analytical approaches. The dynamic structure factor, experimentally measurable by Bragg spectroscopy, is studied in three
