The majority-spin carrier effective mass renormalization of the Q2D system is studied within the leading-order dynamical screening approximation. Our treatment takes the image charge effect as well as the effect of layer thickness into account. The numerical results show that the majority-spin carrier effective mass renormalization is considerably influenced by the the effects of image charge and layer thickness.

The effective mass m eff of the Pauli–Fierz Hamiltonian with ultraviolet cutoff Λ and the bare mass m in non-relativistic quantum electrodynamics (QED) with spin ½ is investigated. Analytic properties of m eff in coupling constant e are shown. Let us set [Formula: see text]. The explicit form of constant a2(Λ/m) depending on Λ/m is given. It is shown that the spin interaction enhances the effective mass and that there exist strictly positive constants c1 and c2 such that [Formula: see text] In particular though it is known that a1(Λ/m) diverge log (Λ/m) as Λ → ∞, a2(Λ/m) does not diverge as ± [ log (Λ/m)]2 but -(Λ/m)2.

Adiabatic large polarons in anisotropic molecular crystals We study the large polaron whose motion is confined to a single chain in a system composed of the collection of parallel molecular chains embedded in threedimensional lattice. It is found that the interchain coupling has a significant impact on the large polaron characteristics. In particular, its radius is quite larger while its effective mass is considerably lighter than that estimated within the one-dimensional models. We believe that our findings should be taken into account for the proper understanding of the possible role of large polarons in the charge and energy transfer in quasi-one-dimensional substances.
