Modeling Atomic Polarizability: From Charge Distortion to Non-Uniform Distributions
O. F. de Alcantara Bonfim
In the classical model of atomic polarizability, atomic charges are displaced by an applied electric field, assuming the electron cloud remains spherically symmetric but with its c…

Ground-state properties of the one-dimensional transverse Ising model in a longitudinal magnetic field
O. F. de Alcantara Bonfim, B. Boechat, J. Florencio
The critical properties of the one-dimensional transverse Ising model in the presence of a longitudinal magnetic field were studied by the quantum fidelity method. We used exact di…
