Disorder-induced phase transitions in a spinful one-dimensional system

We analyse a modified set of renormalisation group equations for disordered spinful fermions described by the Luttinger liquid model. The modification is necessary to take special care factitious admixture disorder interaction coupling constants undergoing renormalisation. Only properly separated amplitudes elastic and inelastic processes allow identification true phases construction phase diagram (a similar procedure has been earlier implemented spinless case). In case, these enable us demonstrate that in some region bare parameters values contains two massive phases, charge (CDW) spin (SDW) density waves, which are an insulating phase. These gapped achieved at finite critical temperatures vanish boundaries indicating presence disorder-induced quantum transition. as function reasonably well fit stretch exponential with universal stretching exponent ?=1/3. A transition between CDW SDW driven strength not predicted before this observation must be taken into account when analysing recent multiple experiments on transitions quasi-one-dimensional structures.
