The Lyotropic State of Matter: Molecular Physics and Living Matter Physics

Physics 7450 : Solid State Physics 2 Lecture 3 : Bosonic matter

Abstract In these lectures, starting with a review of secondand coherent-state path-integral quantization, we will formulate a quantum field theory of bosonic matter and will study its thermodynamics and correlation functions. We will explore the transition to Bose-Einstein condensation (BEC) of noninteracting bosons. Including interactions, we will study the properties of a superfluid and a ph...

Physics of Strange Matter

All known nuclei are made of the two nucleons, the proton and the neutron. Besides those two lightest baryons there exist still a couple of other stable (but weakly decaying) baryons, the hyperons. These were found for the first time in cosmic ray experiments and were entitled as ‘strange’ because of their unusual long lifetimes of about 10−10 sec. For their notation in the hadron zoo of elemen...

The key insight of Bogoliubov is that although the mean-field Hamiltonian (1) is clearly not diagonal in the space of states created by the operators ck,↑/↓, it may be diagonal in a basis of states created by operators related to these via a simple SU2 transformation. Indeed, it may be the case that ‘electrons’ and ‘holes’ are the wrong degrees of freedom to consider; we should at least look to...
