We have investigated the formation of a quantum glass at finite temperatures in low-density two-dimensional conducting systems in semiconductor heterostructures. Using a memory function formalism we have determined the quantum glass melting curve for weak disorder as a function of density and temperature, and show that the glass-liquid transition is only weakly affected by increasing temperature at the least up to the Fermi temperature.

Abstract
We have investigated the formation of a quantum glass at finite temperatures in low-density two-dimensional conducting systems in semiconductor heterostructures. Using a memory function formalism we have determined the quantum glass melting curve for weak disorder as a function of density and temperature, and show that the glass-liquid transition is only weakly affected by increasing temperature at the least up to the Fermi temperature.File in questo prodotto:
