DEFORMABLE QUANTUM INDUCTANCE (RING) INTERACTING WITH A PHONON FIELD: PERSISTENT ELECTRICAL CURRENTS RE-VISITED ((q<sub>e</sub>/ℏ) VERSUS (2q<sub>e</sub>/ℏ))
(World Scientific, 2010) M. Calcina; J.C. Flores
The Hamiltonian of a flexible purely inductive quantum circuits, with discrete charge (q e ), coupled to the vibrational degrees of a lattice (phonons) is presented. In the static regime, when the inductance is threaded by an external fixed magnetic flux, the usual periodic behavior in the persistent electrical current (frequency q e /ℏ) becomes altered. A new harmonic appears which is twice that of the fundamental (2q e /ℏ). All this is the consequence of the geometric static deformation in the inductance produced by the persistent electrical current itself (Lorentz force).
Griffith theory of physical fractures, statistical procedures and entropy production: Rosetta stone’s legacy
(Public Library of Science, 2023) M. Calcina-Nogales; Boris Atenas; J.C. Flores
A physical model, based on energy balances, is proposed to describe the fractures in solid structures such as stelae, tiles, glass, and others. We applied the model to investigate the transition of the Rosetta Stone from the original state to the final state with three major fractures. We consider a statistical corner-breaking model with cutting rules. We obtain a probability distribution as a function of the area and the number of vertices. Our generic results are consistent with the current state of the Rosetta Stone and, additionally, predictions related to a fourth fracture are declared. The loss of information on such heritage pieces is considered through entropy production. The explicit quantification of this concept in information theory stays examined.
