Polaron model of a pseudogap state in quasi-one-dimensional systems

Orlov, Yu. S.; Dudnikov, V. A. JOURNAL OF EXPERIMENTAL AND THEORETICAL PHYSICS, 125 (5):798-809; 10.1134/S1063776117110103 NOV 2017

A brief overview of the basic concepts and problems of the physics of quasi-one-dimensional (q1D) compounds is given. A consistent theoretical description of the nature of the so-called pseudogap state still remains the main problem. A simplified model of the pseudogap state based on the formation of smallradius polarons is considered within the cluster perturbation theory.
