Effective Hamiltonians and Phase Diagrams for Tight-Binding Models

Nilanjana Datta, Roberto Fernandez, Juerg Froehlich

We present rigorous results for several variants of the Hubbard model in the strong-coupling regime. We establish a mathematically controlled perturbation expansion which shows how…

Problems with the definition of renormalized Hamiltonians for momentum-space renormalization transformations

Aernout C. D. van Enter, Roberto Fernández

For classical lattice systems with finite (Ising) spins, we show that the implementation of momentum-space renormalization at the level of Hamiltonians runs into the same type of d…

A Problem of Relative, Constrained Motion

Oscar Bolina, J. R. Parreira

We develop a new method to determine the acceleration of a block sliding down along the face of a moving wedge. We have been able to link the solution of this problem to that of th…
