The Luttinger Model is the only model of many-fermion physics with legitimate claims to be both exactly and completely solvable. In several respects it plays the same role in many-body theory as does the 2D Ising model in statistical physics.Interest

This theoretical study of superconductivity examines repulsive forces that, surprisingly, favor the BCS paired state. The value of Tc and the pairing symmetry (s-, p-, d-wave) are obtained exactly as eigenvalues in a given sector of a Fredholm integr

We examine states of electrons confined to the conduction band of an intrinsic semiconductor that is cut up into various geometric shapes. In the case of a repetitive pattern such as an antidot lattice, mini-Bloch sub-bands condense out of the conduc

We argue that the usual Hubbard's model produces only s-wave pairing functions and, even then, only at unphysically large values of the lumped parameter J≡4t2/U. It follows that a reliable theory of high-Tc superconductivity has to include addition

We design a two-dimensional ferromagnet of quantum spheres of radius O(10 nm3) made of nonmagneticintrinsic semiconducting material, each connected to its neighbors by nano-cylinders made of identical material. Ferromagnetism ensues if there is preci

We estimate the relative radial and angular correlation energies in the ground state of two-electron ions, such as in the hydrogen negative ion, the helium atom and the lithium positive ion, and find they are roughly equal.

We examine the distribution of normal modes in amorphous or glassy materials. Thermodynamical considerations suggest an unusually high density of low-lying states in such materials. Here we inquire into the dynamics, using the appropriate Green funct

Cracks are known to form easily along certain crystallographic directions, presumably because of weaker bonds or lower coordination numbers along those directions. We uncover the manner in which such weak bonds break as the temperature is raised, by

In the Luttinger model, right-hand-going particles moving at a constant velocity c in 1D maintain a constant distance apart. Therefore their interaction energy should be a trivial constant of the motion whereas, in fact it is not. This interaction af
