Physics Colloquia Series Presents: 27 January 2017: Prof Nicola Spaldin, ETH Zurich; From Materials to Cosmology: Studying the early universe under the microscope

The behaviour of the early universe just after the Big Bang is one of the most intriguing basic questions in all of science, and is extraordinarily difficult to answer because of insurmountable issues associated with replaying the Big Bang in the laboratory. One route towards the answer -- which lies at the intersection between cosmology and materials physics -- is to use laboratory materials to test the so-called "Kibble-Zurek" scaling laws proposed for the formation of defects such as cosmic strings in the early universe.

Physics Colloquium Nov 11: Professor Jon Rosner (Chicago), 'Exotic combinations of quarks - A journey of fifty years'

The early 1960s witnessed a wealth of elementary particles described in terms of simple combinations of a few more elementary units, dubbed quarks. The known mesons and baryons could all be described as states of quark-antiquark or three quarks. However, it was not understood why certain more elaborate combinations, such as (two quarks + two antiquarks) or (four quarks + one antiquark) had not been observed. It has taken nearly half a century, but these "exotic" particles are now beginning to be seen and understood.

Physics Colloquia Series Presents: Astro Special - Dr Jamie Holder,University of Delaware, presents 'Astronomy at the Highest Energies: Exploring the Extreme Universe with Gamma Rays'

The gamma-ray band of the electromagnetic spectrum probes some of the most extreme environments in the Universe. Photons of these very-high energies can only be produced by the interactions of subatomic particles that have been accelerated to almost the speed of light. This acceleration occurs in a surprisingly wide variety of astrophysical sources: close to black holes and neutron stars, in the blast waves of supernova explosions, and in the relativistic jets of active galaxies.

Physics Colloquia Series Presents: Dr. Trevor Cross,Group Chief Technology Officer, e2v, entitled '60 years of imaging technology'

From the earliest commercial production of electronic image sensors for television in the 1950s, to the diverse application of specialist silicon image sensors for the Hubble space Telescope to digital dentistry this talk will outline the manufacturing technology and changes through 60 years at e2v. Somewhat surprisingly, there are today lessons to be learned, and technologies to be applied from this to the emerging new platform technology of ultra-cold atom sensing and metrology.
