Predator-Prey Interactions between Droplets Driven by Nonreciprocal Oil Exchange

Caleb H. Meredith, Pepijn G. Moerman, Jan Groenewold +4

Chemotactic interactions are ubiquitous in nature and can lead to nonreciprocal and complex emergent behavior in multibody systems. Here we show how chemotactic signaling between m…

Holographic Wilson Lines as Screened Impurities

Nick Evans, Andy O'Bannon, Ronnie Rodgers

In Landau Fermi liquids, screened impurities support quasi-bound states, representing electrons bound to the impurity but making virtual excursions away. Signals of these quasi-bou…

Angular Momentum Conservation and Phonon Spin in Magnetic Insulators

Andreas Rückriegel, Simon Streib, Gerrit E. W. Bauer +1

We develop a microscopic theory of spin-lattice interactions in magnetic insulators, separating rigid-body rotations and the internal angular momentum, or spin, of the phonons, whi…
