Transport in Single Quantum Dots: A Review from Linear Response to Nonlinear Regimes
Gustavo Diniz, Silvio Quintino, Vivian V. França
Quantum dots are versatile systems for exploring quantum transport, electron correlations, and many-body phenomena such as the Kondo effect. While equilibrium properties are well u…
Analytical Diagonalization of Fermi Gas-like Hamiltonians using the Sommerfeld-Watson Transformation
G. Diniz, F. D. Picoli, M. P. Lenzarini
The Sommerfeld-Watson transformation is a powerful mathematical technique widely used in physics to simplify summations over discrete quantum numbers by converting them into contou…
Tracking Adiabaticity in Non-Equilibrium Many-Body Systems: The Hard Case of the X-ray Photoemission in Metals
G. Diniz, F. D. Picoli, L. N. Oliveira +1
The level of adiabaticity determines many properties of time-dependent quantum systems. However, a reliable and easy-to-apply criterion to check and track it remains an open questi…
Sticking coefficient for atoms impinging on a metallic surfaces, and the x-ray photoemission by metals
Gustavo Diniz
Out-of-equilibrium electron-gas systems exhibit rich physics, which we explore through three problems. First, we study photoemission from metals, traditionally analyzed in the freq…
