A planar diagram approach to the correlation problem

D. Foerster

We transpose an idea of 't Hooft from its context of Yang and Mills' theory of strongly interacting quarks to that of strongly correlated electrons in transition metal oxides and s…

Nonminimal Derivative Couplings and Inflation in Generalized Theories of Gravity

S. Capozziello, G. Lambiase, H. -J. Schmidt

We study extended theories of gravity where nonminimal derivative couplings of the form are present in the Lagrangian. We show how and why the other coupling…

A one-dimensional lattice model for a quantum mechanical free particle

A. C. de la Torre

Two types of particles, A and B with their corresponding antiparticles, are defined in a one dimensional cyclic lattice with an odd number of sites. In each step of time evolution,…

Analytic residue theory in the non-complete intersection case

C. A. Berenstein, A. Yger

In previous work of the authors and their collaborators (see Progress in Math, vol. 114, Birkäuser, 1993) it was shown how the equivalence of several constructions of residue curre…

On some generalizations of Jacobi's Residue Formula

A. Vidras, A. Yger

Using Bochner-Martinelli type residual currents we prove some generalizations of Jacobi's Residue Formula, which allow proper polynomial maps to have `common zeroes at infinity', i…

Time-dependent calculation of ionization in Potassium at mid-infrared wavelengths

P. Maragakis, E. Cormier, P. Lambropoulos

We study the dynamics of the Potassium atom in the mid-infrared, high intensity, short laser pulse regime. We ascertain numerical convergence by comparing the results obtained by t…
