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...

Tristan McLoughlin (Dublin): Twistors and Conformal Higher-Spin Theory

Higher-spin fields can play an important role in effective field theories and increasingly are of interest due to their appearance in recent studies of holography. Understanding their interactions is however often involved and...

Ernst Pernicka (Germany): Authentic and fake gold: Analytical investigations of archaeological gold finds

Gold was valued highly in all cultures and all periods and the associated symbolisms are also very similar. Its practical value, however, is rather low. Accordingly, gold was mainly used for ritual objects and as medium for...

Robert Seiringer (ISTA): The excitation spectrum in a Bose fluid

Of particular relevance for an understanding of the low-temperature properties of a quantum system is the excitation spectrum. With the exception of exactly solvable models in one dimension, rigorous results on its structure are...

Byung Il Min (Korea): Electronic structures and topological properties of f-electron mixed-valent/Kondo systems

A great deal of recent attention has been paid to the topological nature in f-electron systems including a mixed-valent/Kondo insulator SmB6. We have investigated the topological properties of SmB6, based on the dynamical...

Symposium Walter Thirring - In Memoriam

A symposium on the occasion of his 90th Birthday

Walter Thirring (29 April 1927 - 18 August 2014) was one of Austria’s most distinguished physicists during his long professional career. He made seminal contributions to many...

Armando Rastelli (Linz): Epitaxial Quantum Dots as Scalable Sources of Single and Polarization Entangled Photons

Several systems are under investigation for their potential use in the fields of quantum information and communication. Semiconductor quantum dots (QDs), also dubbed “artificial atoms”, are one of such systems, as they can be...
