Flow of time during energy measurements and the resulting time-energy uncertainty relations
Ismael L. Paiva, Augusto C. Lobo, Eliahu Cohen
Uncertainty relations play a crucial role in quantum mechanics. Well-defined methods exist for the derivation of such uncertainties for pairs of observables. Other approaches also…
Weak Values and Modular Variables From a Quantum Phase Space Perspective
Augusto C. Lobo, Yakir Aharonov, Jeff Tollaksen +2
We address two major conceptual developments introduced by Aharonov and collaborators through a \textit{quantum phase space} approach: the concept of \textit{modular variables} dev…
Classical Structures in Quantum Mechanics and Applications
Augusto Cesar Lobo, Clyffe de Assis Ribeiro
The theory of Non-Relativistic Quantum Mechanics was created (or discovered) back in the 1920's mainly by Schrödinger and Heisenberg, but it is fair enough to say that a more moder…
Geometry of the adiabatic theorem
A. C. Lobo, R. A. Ribeiro, P. R. Dieguez +1
We present a simple and pedagogical derivation of the quantum adiabatic theorem for two level systems (a single qubit) based on geometrical structures of quantum mechanics develope…
The geometry of von-Neumann's pre-measurement and weak values
A. C. Lobo, C. A. Ribeiro
We have carried out a review of a paper from Tamate et al, conducting a deeper study of the geometric concepts they introduced in their paper, clarifying some of their results and…
Proper and improper density matrices and the consistency of the Deutsch model for Local Closed Timelike Curves
A. C. Lobo, I. L. Paiva, P. R. Dieguez
We discuss the concept of proper and improper density matrixes and we argue that this issue is of fundamental importance for the understanding of the quantum-mechanical CTC model p…
