Quartic Fourier-Laplace limits for -Rogers-Szegő polynomials

Per Åhag, Rafał Czyż, Per-Håkan Lundow

We prove asymptotic formulae for positive real -Rogers-Szegő polynomials when the quadratic term in the expansion about the middle coefficient vanishes. For coefficient indi…

On -binomial coefficient ratios for complex parameters

Per Åhag, Rafał Czyż, Per-Håkan Lundow

We prove local asymptotics for near-central complex -binomial coefficient moduli ratios allowing an imaginary parameter perturbation of order at a leng…

Boundary effects on finite-size scaling for the 5-dimensional Ising model

P. H. Lundow

High-dimensional () Ising systems have mean-field critical exponents. However, at the critical temperature the finite-size scaling of the susceptibility depends on the…

Efficient computation of permanents, with applications to boson sampling and random matrices

P. H. Lundow, K. Markström

In order to find the outcome probabilities of quantum mechanical systems like the optical networks underlying Boson sampling, it is necessary to be able to compute the permanents o…

Hyperscaling violation in Ising Spin Glasses

P. H. Lundow, I. A. Campbell

In addition to the standard scaling rules relating critical exponents at second order transitions, hyperscaling rules involve the dimension of the model. It is well known that in c…

Revisiting the cavity-method threshold for random 3-SAT

P. H. Lundow, K. Markström

A detailed Monte Carlo-study of the satisfiability threshold for random 3-SAT has been undertaken. In combination with a monotonicity assumption we find that the threshold for rand…
