Recent advances in the calculation of dynamical correlation functions
J. Florencio, O. F. de Alcantara Bonfim
We review various theoretical methods that have been used in recent years to calculate dynamical correlation functions of many-body systems. Time-dependent correlation functions an…

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…

Quantum fidelity approach to the ground state properties of the 1D ANNNI model in a transverse field
O. F. de Alcantara Bonfim, B. Boechat, J. Florencio
In this work we analyze the ground-state properties of the one-dimensional ANNNI model in a transverse field using the quantum fidelity approach. We numerically determined…
