Bending and Stretching in a Narrow Ribbon of Nematic Polymer Networks

We study the spontaneous out-of-plane bending of a planar untwisted ribbon composed of nematic polymer networks activated by a change in temperature. Our theory accounts for both stretching and bending energies, which compete to establish equilibrium. We s ...

Transient phenomena in the axion assisted Schwinger effect

Valerie Fiona Domcke

Particle production induced by a time-dependent background is well understood as the projection of the time-evolved initial state onto a set of final states. While the asymptotic initial and final states are well defined in the usual way, the definition of ...

Unidirectional Kondo scattering in layered NbS2

László Forró, Helmuth Berger, Oleg Yazyev, Christoph Koch, Quansheng Wu, Philip Johannes Walter Moll, Matthias Carsten Putzke, Edoardo Martino, Shengnan Zhang, Konstantin Semeniuk

Crystalline defects can modify quantum interactions in solids, causing unintuitive, even favourable, properties such as quantum Hall effect or superconducting vortex pinning. Here we present another example of this notion-an unexpected unidirectional Kondo ...
