Quantifying the effect of temporal resolution on time-varying networks
Bruno Ribeiro, Nicola Perra, Andrea Baronchelli
Time-varying networks describe a wide array of systems whose constituents and interactions evolve over time. They are defined by an ordered stream of interactions between nodes, ye…
Modular Subgroups, Dessins d'Enfants and Elliptic K3 Surfaces
Yang-Hui He, John McKay, James Read
We consider the 33 conjugacy classes of genus zero, torsion-free modular subgroups, computing ramification data and Grothendieck's dessins d'enfants. In the particular case of the…
Entanglement in permutation symmetric states, fractal dimensions, and geometric quantum mechanics
Olalla A. Castro-Alvaredo, Benjamin Doyon
We study the von Neumann and Rényi bipartite entanglement entropies in the thermodynamic limit of many-body quantum states with spin-s sites, that possess full symmetry under excha…
Involutive A-infinity algebras and dihedral cohomology
Christopher Braun
We define and study the cohomology theories associated to A-infinity algebras and cyclic A-infinity algebras equipped with an involution, generalising dihedral cohomology to the A-…
How can large-scale twisted magnetic structures naturally emerge from buoyancy instabilities?
B. F. N. Favier, L. Jouve, W. Edmunds +2
We consider the three-dimensional instability of a layer of horizontal magnetic field in a polytropic atmosphere where, contrary to previous studies, the field lines in the initial…
Magnetic buoyancy instabilities in the presence of magnetic flux pumping at the base of the solar convection zone
Adrian J. Barker, Lara J. Silvers, Michael R. E. Proctor +1
We perform idealised numerical simulations of magnetic buoyancy instabilities in a model of the solar tachocline. We introduce a simplified model of magnetic flux pumping in an upp…
Brane Geometry and Dimer Models
Yang-Hui He, Vishnu Jejjala, Diego Rodriguez-Gomez
The field content and interactions of almost all known gauge theories in AdS_5/CFT_4 can be expressed in terms of dimer models or bipartite graphs drawn on a torus. Associated with…
Quantum Wire Network with Magnetic Flux
Vincent Caudrelier, Mihail Mintchev, Eric Ragoucy
The charge transport and the noise of a quantum wire network, made of three semi-infinite external leads attached to a ring crossed by a magnetic flux, are investigated. The system…
