Kondo lattice model: Unitary transformations, spin dynamics, strongly correlated charged modes, and vacuum instability
J. M. Prats, F. Lopez-Aguilar
Using unitary transformations, we express the Kondo lattice Hamiltonian in terms of fermionic operators that annihilate the ground state of the interacting system and that represen…

Spin fluctuations of a random vacuum state: a new approach to the Kondo lattice
J. M. Prats, F. Lopez-Aguilar
We address the Kondo lattice with one conduction band by introducing a representation of the (s=1/2) local moments consisting in an s=1 triplet of spin fluctuations of a vacuum sta…

An Alternative Perturbative Expansion in Quantum Mechanics. Scaling and cut-off Resummation
J. M. Prats
An alternative perturbative expansion in quantum mechanics which allows a full expression of the scaling arbitrariness is introduced. This expansion is examined in the case of the…
