At 5 electrons per cell, planar CuO 2 is an antiferromagnetic insulator rather than a Fermi liquid. We consider the effects of adding a few electrons or holes into such an insulator and derive a relation between the insulating energy gap and effective mass m* of the added carriers. We find [Formula: see text]to differ from [Formula: see text], with both being temperature dependent.

In this paper I report my solution to MBX Challenge Competition. Namely, the Bertsch, nonparametric model of neutron matter is analyzed and strong indications are found that, in the infinite system limit, the ground state is a Fermi liquid with an effective mass.

Dynamical Screening

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.
