Gravitational friction from d'Alembert's principle

C. Ortiz, R. S. Khatiwada

The least action principle played a central role in the development of modern physics. A major drawback of the principle is that its applicability is limited to holonomic constrain…

Quantum Black Hole as a Harmonic Oscillator from the Perspective of the Minimum Uncertainty Approach

Wilfredo Yupanqui Carpio, Octavio Obregón

Starting from the eigenvalue equation for the mass of a black hole derived by Mäkelä and Repo, we show that, by reparametrizing the radial coordinate and the wave function, it can…

Energy-time uncertainty relation from entropy measures

Nana Cabo Bizet, Octavio Obregón, Wilfredo Yupanqui Carpio

In a previous study, it was shown that the Generalized Uncertainty Principle (GUP) can be derived from non-extensive entropies, particularly those depending only on the probability…
