Volovik\nby Krzys ztof Pomorski (University College Dublin) as part of QM Foundations & Natu re of Time seminar\n\n\nAbstract\nThere are fundamental relations between three vast areas of physics: particle physics\, cosmology\, and condensed matter physics. The fundamental links between the first two areas — in o ther words\, between micro- and macro-worlds — have been well establishe d. There is a unified system of laws governing the scales from subatomic p articles to the cosmos and this principle is widely exploited in the descr iption of the physics of the early universe. This book aims to establish a nd define the connection of these two fields with condensed matter physics . According to the modern view\, elementary particles (electrons\, neutrin os\, quarks\, etc.) are excitations of a more fundamental medium called th e quantum vacuum. This is the new ‘aether’ of the 21st century. Electr omagnetism\, gravity\, and the fields transferring weak and strong interac tions all represent different types of the collective motion of the quantu m vacuum. Among the existing condensed matter systems\, a quantum liquid c alled superfluid 3He-A most closely represents the quantum vacuum. Its qua siparticles are very similar to the elementary particles\, while the colle ctive modes are analogues of photons and gravitons. The fundamental laws o f physics\, such as the laws of relativity (Lorentz invariance) and gauge invariance\, arise when the temperature of the quantum liquid decreases. \ n\nBook: http://www.issp.ac.ru/ebooks/books/open/The_Universe_in_a_Helium_ Droplet.pdf\n LOCATION:https://researchseminars.org/talk/QMFNoT/3/ END:VEVENT END:VCALENDAR
