Arbitrary Lagrangian-Eulerian discontinuous Galerkin method for conservation laws on moving simplex meshes

Pei Fu, Gero Schnücke, Yinhua Xia

In Klingenberg, Schnücke and Xia (Math. Comp. 86 (2017), 1203-1232) an arbitrary Lagrangian-Eulerian discontinuous Galerkin (ALE-DG) method to solve conservation laws has been deve…

Detection and characterization of an ultra-dense sub-Neptune planet orbiting the Sun-like star HD 119130

R. Luque, G. Nowak, E. Pallé +51

We present the discovery and characterization of a new transiting planet from Campaign 17 of the Kepler extended mission K2. HD 119130 b is a warm sub-Neptune on a 17-d orbit aroun…

Dust charge distribution in the interstellar medium

Juan C. Ibáñez-Mejía, Stefanie Walch, Alexei V. Ivlev +3

We investigate the equilibrium charge distribution of dust grains in the interstellar medium (ISM). Our treatment accounts for collisional charging by electrons and ions, photoelec…

Probing transport in quantum many-fermion simulations via quantum loop topography

Yi Zhang, Carsten Bauer, Peter Broecker +2

Quantum many-fermion systems give rise to diverse states of matter that often reveal themselves in distinctive transport properties. While some of these states can be captured by m…
