PEGASUS Seminar Series: Exact Solutions to Einstein-Maxwell theory (Vineet Kumar)

Please join us this Tuesday, July 26 in Physics 175 for our next presentation in our PEGASUS Summer Seminar Series.
Our next speaker is Vineet Kumar, who studies electromagnetic behaviour in curved spacetime.
There will be cookies and refreshments served beforehand at 3:00 pm in the lounge for those attending the seminar.
Title: Exact Solutions to Einstein-Maxwell theory
 
Abstract: We construct explicit analytical exact solutions to the four and higher dimensional Einstein-Maxwell theory. All solutions are constructed by embedding a solution to Einstein equations in higher dimensions. Several solutions will be briefly discussed including two helicoidal solutions, one embedding Schwarzschild and one embedding the Eguchi-Hanson space. In the case of the Eguchi-Hanson embedded solution, we find that the solutions can be extended to non-stationary exact solutions to Einstein-Maxwell theory with cosmological constant and that the solutions are asymptotically expanding patches of de-Sitter spacetime.

PEGASUS Seminar Series: The hidden world – Higgs, dark matter and conformal symmetry (Zhi-Wei Wang)

Please join us this Tuesday, July 19th in Physics 175 for our next presentation in our PEGASUS Summer Seminar Series.
Our next speaker is Zhi Wei Wang, who investigates models to solve important problems in physics including dark matter.

Title:The hidden world: Higgs, dark matter and conformal symmetry
 
Abstract: This talk will address the two most important topics in particle physics in the LHC era: Higgs and dark matter. The Higgs mass suffers from the well-known hierarchy/naturalness problem and a custodial symmetry is needed. In this talk, I will show conformal symmetry as a non-conventional custodial symmetry protects the Higgs mass from UV sensitivity. In addition, the Standard Model with hidden sector extensions provide ideal dark matter candidates and interesting collider signatures. Combining the idea of conformal symmetry and hidden sectors, I will introduce the conformally-symmetric hidden sector where both the hierarchy problem and dark matter are addressed.

PEGASUS Seminar Series: P-block elements – the next generation (Thomas Tolhurst)

Please join us this Tuesday, July 12th in Physics 126 (please note the temporary room number change!for our next presentation in our PEGASUS Summer Seminar Series.
Our next speaker is Thomas, who studies the properties of materials using computational methods and experimental techniques such as soft x-ray spectroscopy.
There will be cookies and refreshments served beforehand at 3:00 pm in the lounge for those attending the seminar.
Title: P-block elements – the next generation
Abstract:

Soft x-ray spectroscopy is an experimental technique that provides a unique perspective on many
important material properties. When combined with first principles electronic structure calculations, everything from the bulk band gap, to site-specific charge densities can be determined and understood. This talk will look at the application of these techniques to several technologically important nitrides and oxides, and emphasize how they can provide information on the structure-property relationships that are key to engineering new materials
