Extreme States of Matter: From Big Bang to the Lab
October 28, 2020 @ 5:30 pm - 6:30 pm
Public Lecture by Dr Dimitrios Giataganas, University of Athens
States of strongly interacting matter at extremely high temperatures of five trillion degrees Celsius and high density existed in the very early stages of the evolution of the universe. This quantum state of matter is created today for a fraction of the second at the large hadron collider lab by densely colliding ultra-relativistic particles to heat up and melt the ordinary matter we experience in our everyday life. In these exotic conditions we can probe the properties of nature at its finest, where the origin of many fundamental puzzles lies. Despite our tremendous efforts, their theoretical understanding remains challenging. An exciting approach in this direction is the so-called gauge/gravity duality, a systematic way to map quantum physics that are difficult to model theoretically, to an equivalent artificial gravity theory which is theoretically tractable. Interestingly, using the duality to understand the creation, the evolution and the properties of the extreme states of matter, surprising and unexpected additional puzzles arise, such as: Does nature set bounds on how perfect a fluid can be? and, What is the most perfect fluid? In this talk we will discuss the current status of the on-going research on such exotic physics.
This lecture is free and open to all.
