Critical temperature for phase transitions in charged-particle assemblies

A variety of phase transitions in both three- and two-dimensional assemblies of charged particles, with or without superfluidity, are compared and contrasted. Included here are (i) electron-hole droplets in five semiconductors, (ii) critical point properties of liquid alkali metals, (iii) transition temperature for non-s-wave pairing superconductors correlated with coherence length, and (iv) excitonic assemblies involving Bose-Einstein condensation.
