Ask zeta functions of central hyperplane arrangements
Alec Schmutz
Given a central hyperplane arrangement defined over a field of characteristic zero, we construct matrices of linear forms whose local ask zeta functions are recovered…

Observation of sine-Gordon-like solitons in a spinor Bose-Einstein condensate
Yannick Deller, Alexander Schmutz, Raphael Schäfer +7
We experimentally generate sine-Gordon-like solitons in a spin-1 spinor Bose-Einstein condensate (BEC) utilizing a robust and reproducible local phase-imprinting scheme. We find th…

Double sine-Gordon class of universal coarsening dynamics in a spin-1 Bose gas
Ido Siovitz, Anna-Maria E. Glück, Yannick Deller +5
Far from equilibrium, universal dynamics prevails in many different situations, from pattern coarsening to turbulence. A central longstanding problem concerns the development of a…
