By Grigory E. Volovik
There are primary kin among 3 colossal parts of physics: particle physics, cosmology and condensed subject physics. the elemental hyperlinks among the 1st parts, in different phrases, among micro-and macro-worlds, were good confirmed. there's a unified procedure of legislation governing the scales from subatomic debris to the Cosmos and this precept is commonly exploited within the description of the physics of the early Universe. the most aim of this booklet is to set up and outline the relationship of those fields with condensed topic physics.
According to the trendy view, simple debris (electrons, neutrinos, quarks, etc.) are excitations of a extra primary medium known as the quantum vacuum. this can be the recent 'aether' of the twenty first Century. Electromagnetism, gravity, and the fields moving vulnerable and robust interactions all characterize kinds of the collective movement of the quantum vacuum. one of the latest condensed subject platforms, a quantum liquid known as superfluid 3He-A such a lot heavily represents the quantum vacuum. Its quasiparticles are similar to the straight forward debris, whereas the collective modes are analogues of photons and gravitons. the basic legislation of physics, comparable to the legislation of relativity (Lorentz invariance) and gauge invariance, come up whilst the temperature of the quantum liquid decreases.
