Abstract
An explanation of some phases of the organic insulator (TMTTF)(2)PF6 as a f unction of temperature, magnetic field, and pressure is given. It is shown that the problem can be mapped onto the (2 + 1)-dimensional nonlinear sigma model. The physics is described in terms of the coupling constant of this model, which encodes the one-dimensional two-body interactions and phonon e ffects. A phase diagram is proposed, including a possible quantum critical fixed point. [S0163-1829(99)01007-3].
