Benedikt Fauseweh, Max Planck Institute for Solid State Research

Due to perosnal reasons Benedikt Fauseweh will unfortunately be unable to join us for this CM-Seminar.

We hope to be able to re-schedule a visit for him at SBQMI at a later date. Thank you for your comprehension.

The recently discovered monolayer transition metal dichalcogenides (TMDs) are 2D crystalline semiconductors with unique spin-valley properties. They have a pair of valleys that, by time-reversal symmetry, are energetically degenerate. Lifting the valley degeneracy in these materials is of great interest because it would allow for valley specific band engineering. In this talk, I will show that off resonant, circularly polarized light can be used to lift the valley degeneracy by means of the optical Stark effect.

Optoelectronic devices are used to detect and manipulate light for communications, sensing, solar power generation, etc. However, even in the dark (i.e. when no photons are present), there exist quantum fluctuations of electromagnetic fields (sometimes called virtual photons) that give rise to measurable effects. One such phenomenon is a force between two charge-neutral objects, known as the Casimir effect.

The discovery in 2010, using superconductor / ferromagnet / superconductor Josephson junctions, that it is possible to controllably create triplet Cooper pairs in which the electrons have parallel spins created the field of superconducting spin electronics (superspintronics) [1]. However, even if triplet pairing implies that supercurrents can carry spin, this is not in itself sufficient to create functioning superspintronic devices.  In parallel, a variety of other interactions between singlet superconductivity and magnetism have been actively explored.
