SYGT: Symposium Geometry, Topology, and Condensed Matter

SYGT 1: Geometry, topology, and condensed matter

Dienstag, 2. April 2019, 09:30–12:15, H1

Extending two-dimensional structures into the three-dimensional (3D) space has become a general trend in multiple disciplines, including electronics, photonics, plasmonics and magnetics. This approach provides means to modify conventional or to launch novel functionalities by tailoring curvature and 3D shape. Shape deformations – which result in a non-uniform curvature – give rise to complex 3D spin textures unveiling the way to get an all-electrical and all-geometrical control of the electron spin orientation, anticipating an unbound potential for new concepts in spin-orbitronics, where the electron spin and the electronic transport are directly controlled by the system geometry. The Symposium will cover broad range of disciplines in condensed matter, namely semiconductors, superconductors, magnetism. Furthermore, we deliberately bring the topic of nematic liquid crystal shells with the aim to reveal similarities and differences in the fundamental properties of soft matter and condensed matter systems.
