Real-space renormalization-group study of decoherence and revival following a sudden quench in a finite system
Felipe D. Picoli, Gustavo Diniz, Luiz N. Oliveira
To investigate the nonequilibrium dynamics of a quantum impurity system, we examine two physical properties for the spinless resonant level model subject to sudden quenches of the…
Monty Hall problem revisited once more
Francisco A. B. Coutinho, Eduardo Massad, Luiz N. Oliveira
The Monty Hal problem is an attractive puzzle. It combines simple statement with answers that seem surprising to most audiences. The problem was thoroughly solved over two decades…
How sharply does the Anderson model depict a single-electron transistor?
Krissia Zawadzki, Luiz N. Oliveira
The single-impurity Anderson model has been the focus of theoretical studies of molecular junctions and the single-electron transistor, a nanostructured device comprising a quantum…
Entanglement in finite quantum systems under twisted boundary conditions
Krissia Zawadzki, Irene D'Amico, Luiz N. Oliveira
In a recent publication, we have discussed the effects of boundary conditions in finite quantum systems and their connection with symmetries. Focusing on the one-dimensional Hubbar…
Symmetries and boundary conditions with a twist
Krissia Zawadzki, Luiz Nunes de Oliveira, Irene D'Amico
Interest in finite-size systems has risen in the last decades, due to the focus on nanotechnological applications and because they are convenient for numerical treatment that can s…
Kondo dynamics in one-dimensional doped ferromagnetic insulators
Hudson Pimenta, Luiz N. Oliveira, Rodrigo G. Pereira
Some well-established examples of itinerant-electron ferromagnetism in one dimension occur in a Mott-insulating phase. We examine the consequences of doping a ferromagnetic insulat…
