Physik-Combo

27 Mar 2023, 10:00 → 28 Mar 2023, 17:20 Europe/Berlin

Abbeanum/Ground floor-HS1 - Hörsaal 1 (TPI, FSU Jena)

The Physik-Combo - a transregional training initiative of the RTG 2522 Jena Leipzig - provides in-depth research training in topical areas in the context of "Strong Dynamics and Criticality in Quantum and Gravitational Systems".

Its program consists of mini lecture series or topical reviews delivered by invited experts in the field and project talks contributed by the RTG fellows and guests.

Friends and guests from neighboring universities are welcome to participate.

The event is currently planned without possibility of online participation.

The Physik-Combo continues the tradition of the Mitteldeutsche Physik-Combo. 

Monday 27 March

1 Welcome

2 Bound states in strong interaction physics I

Speaker: Markus Huber

3 Q&A

4 Semiclassical Energy Density of Sine-Gordon Solitons

Classical solutions like Solitons play an important role in quantum field theory, high energy physics and cosmology, such it is worthwhile to investigate them in more detail. I will summarize in this talk the results of my master thesis, in which I investigated the semiclassical energy density of solitons in the 1 plus 1 dimensional Sine-Gordon model. In the first part of the talk, I will briefly recapitulate the key methods I used, such as Hadamard point-split renormalization. I will also commend on a subtlety concerning the stress tensor for the 1 plus 1 dimensional scalar field case. The second part follows than with a summary of the corresponding results I gathered for the semiclassical energy density.
