Sun Yan (Germany): Surface Fermi arc states and bulk spin Hall effect in Weyl semimetals

Fermi arc is believed to be one of the most intrinsic proofs for the existence of Weyl semimetals. Our theory calculations in collaboration with ARPES measurement observed the tunable surface Fermi arcs on the surface of...

Johannes Lachner (Wien): Slow anion beams in the spotlight of a green laser

The separation of rare trace isotopes from their isobars, i.e. atoms or molecules of very similar mass, is the major challenge of sensitive mass-spectrometric methods. The experimental setup at the Vienna Environmental Research...

Stefan Hollands (Leipzig): Gravitational Memory, Information, and Black Holes

A burst of gravitational radiation passing through an arrangement of freely falling test masses far from the source will cause a permanent displacement of the masses, called the "gravitational memory". It has recently been found...

Achille Giacometti (Venezia): The physics of the protein folding problem: a possible new perspective?

Vortrag im Rahmen der Chemisch Physikalischen Gesellschaft

Homopolymers are known to form a high temperature swollen (coil) phase and a low temperature phase globular phase. The glassy nature of their ground state stems from the...

Anton Alekseev (Geneva): Path integrals for Wilson lines and Wilson surfaces

Wilson lines in gauge theory admit several path integral presentations based on the theory of coadjoint orbits. We will discuss an interpretation of these theories as 2-dimensional sigma-models using equivariant cohomology and...

Myungshik Kim (London): Single-boson level operations in quantum optics

Dirac writes that the mathematical structure of bosonic operations is one of the most fundamental results of quantum mechanics, which enables a unification of the wave and corpuscular theories of light. The technology to...

Gino Isidori (Zürich): Low-energy hints of physics beyond the Standard Model (starts 14:15!)

Achtung, geänderte Beginnzeit: 14:15

New start time: 14:15

In the last few years a series of hints of deviations from the Standard  Model in B-meson decays have been reported by experiments.  I review these hints,...

Jose P. S. Lemos (Lisbon): Black hole entropy from matter entropy

Lunchseminar

Abstract:

Black hole entropy S is one of the most fascinating issues in contemporary physics, as one does not yet strictly know what are the degrees of freedom at the fundamental microlevel, nor where are they...

Katharina Radermacher (Stockholm): Strong Cosmic Censorship and the initial singularity in Bianchi spacetimes

For given initial data to Einstein's field equations, one can find a spacetime solving these equations, and one can do so in a unique way (up to isometries) if one assumes the spacetime to be maximal globally hyperbolic. Both...
