Fabian Bohnet-Waldraff 1, 2 Daniel Braun 2 Olivier Giraud 1 Physical Review A, American Physical Society, 2017, 96 (3), pp.032312. 〈10.1103/PhysRevA.96.032312〉 We map the quantum entanglement problem onto the mathematically well-studied truncated moment problem. This yields a necessary and sufficient condition for separability that can be checked by a hierarchy of semi-definite programs. The algorithm […]

C. Coquidé 1 Bertrand Georgeot 1 Olivier Giraud 2 EPL – Europhysics Letters, European Physical Society/EDP Sciences/Società Italiana di Fisica/IOP Publishing, 2017, 119 (4), pp.48001. 〈10.1209/0295-5075/119/48001〉 We compare complex networks built from the game of go and obtained from databases of human-played games with those obtained from computer-played games. Our investigations show that statistical features

Hendrik Schawe 1 Alexander K. Hartmann 1 Satya N. Majumdar 2 Physical Review E , American Physical Society (APS), 2017, 96 (6), 〈10.1103/PhysRevE.96.062101〉 The distribution of the hypervolume $V$ and surface $\partial V$ of convex hulls of (multiple) random walks in higher dimensions are determined numerically, especially containing probabilities far smaller than $P = 10^{-1000}$

Jerome Dubail 1 Raoul Santachiara 2 Thorsten Emig 3, 2 Journal of Statistical Mechanics: Theory and Experiment, IOP Science, 2017, pp.033201 Systems as diverse as binary mixtures and inclusions in biological membranes, and many more, can be described effectively by interacting spins. When the critical fluctuations in these systems are constrained by boundary conditions, critical

Lucas Varela 1 Gabriel Téllez 1 Emmanuel Trizac 2 Physical Review E , American Physical Society (APS), 2017, 95 (2), pp.022112 We study a one dimensional Coulomb system, where two charged colloids are neutralized by a collection of point counterions, with global neutrality. Temperature being given, two situations are addressed: the colloids are either kept

Juraj Szavits-Nossan 1 Martin R. Evans 1 Satya N. Majumdar 2 Journal of Physics A: Mathematical and Theoretical, IOP Publishing, 2017, 50 (2), pp.024005 We consider a discrete-time continuous-space random walk under the constraints that the number of returns to the origin (local time) and the total area under the walk are fixed. We first

Joël Bun 1, 2 Jean-Philippe Bouchaud 2 Marc Potters 2 Physics Reports, Elsevier, 2017, 666, pp.1 This review covers recent results concerning the estimation of large covariance matrices using tools from Random Matrix Theory (RMT). We introduce several RMT methods and analytical techniques, such as the Replica formalism and Free Probability, with an emphasis on
