Effect of particle exchange on the glass transition of binary hard spheres

Harukuni Ikeda, Francesco Zamponi

We investigate the replica theory of the liquid-glass transition for a binary mixture of large and small additive hard spheres. We consider two different ansätze for this problem:…

The Query Complexity of a Permutation-Based Variant of Mastermind

Peyman Afshani, Manindra Agrawal, Benjamin Doerr +3

We study the query complexity of a permutation-based variant of the guessing game Mastermind. In this variant, the secret is a pair which consists of a binary string $z \in…

SPHERE dynamical and spectroscopic characterization of HD142527B

R. Claudi, A. -L. Maire, D. Mesa +50

We detect the accreting low-mass companion HD142527B at a separation of 73 mas (11.4 au) from the star. No other companions with mass greater than 10 MJ are visible in the field of…

Precised approximations in elliptic homogenization beyond the periodic setting

Xavier Blanc, Marc Josien, Claude Le Bris

We consider homogenization problems for linear elliptic equations in divergence form. The coecients are assumed to be a local perturbation of some periodic background. We prove $W^…
