Calendar of Physics Talks Vienna

Physics after the lab and the desk: Your work in PRL
Speaker:Sami Mitra (Vienna Physics Colloquium (VPC))
Abstract:Physics research takes place mostly at your desk, at the keyboard, in the lab. You communicate results through posters, talks, and papers -- leading to, hopefully, wide dissemination and recognition. The sequence entails interacting with journal editors, referees, conference chairs, journalists, and so on. I will focus on this post-research collaborative process in physics, primarily through the lens that is Physical Review Letters

High energy behavior of scattering cross sections
Speaker:Prof. Jnanadeva Maharana (Institute of Physics, Bhubaneswar, Indien)
Abstract:There is a lot of interests in the theories in higher dimesional field theories. The research activities are spread over topics such as supersymmetry, supergravity and string theories. It has been argued, since Kaluza and Klein introduced higher dimensional theory, that the extra dimensions are compactified with very small radius. Recent years there proposals arguing that the radius of extra dimensions might be large and the detail phenomenology has been analysed extensively. In this talk, I shall discuss the analyticity properties of scattering amplitude in higher dimensional field theories in a formal setting. I shall recapitulate the known rigorous results of analyticity in D=4 theories derived from field theory. I shall briefly discuss possible tests of such ideas at LHC.

“Good vibrations” - Advanced sensors based on nanomechanical resonators
Speaker:Schmid Silvan (TU Wien, Institute of Sensor and Actuator Systems, Micro and Nanosensors )
Abstract:Pressure sensors, accelerometers, gyroscopes, electronic filters, and Lab-on-a-chip devices are just a few of the most prominent examples of Microelectromechanical Systems (MEMS). MEMS have become omnipresent helpers by making our phones and cars smart and reducing analysis times in modern medical laboratories. Nanoelectromechanical Systems (NEMS) are the little sibling of MEMS. By downscaling the sensing elements from the micro- to the nanoscale, NEMS exhibit unprecedented sensitivities. As a particular achievement, such nanomechanical resonators have created a revolutionary new field of quantum optomechanics, which has enabled quantum mechanical experiments with “macroscopic” devices. Since its beginning two decades ago, NEMS research has been driven mainly by applications in metrology and fundamental science. In our Micro and Nanosensors Group we conduct NEMS research with focus on ad

Stationary black holes with matter fields and a negative cosmological constant
