Quantum criticality and first-order transitions in the extended periodic Anderson model

I. Hagymasi, K. Itai, J. Solyom

We investigate the behavior of the periodic Anderson model in the presence of - Coulomb interaction () using mean-field theory, variational calculation, and exact dia…

Hubbard physics in the symmetric half-filled periodic Anderson-Hubbard model

I. Hagymasi, K. Itai, J. Solyom

Two very different methods -- exact diagonalization on finite chains and a variational method -- are used to study the possibility of a metal-insulator transition in the symmetric…
