“…As expected, we have numerically obtained an analog of the diaelastic effect predicted to occur in a small Josephson contact with Josephson vortices manifesting itself as magnetic field-induced softening of the contact shear modulus C(T,H). In addition to Fraunhofer type field oscillations, C(T,H) it was found to exhibit pronounced flux driven temperature oscillations near TC (Figure 11) as predicted [22].…”

In this review of our own work, we show the physics and applications of Josephson Junction (JJ) and 2D arrays (JJA) made with this powerful quantum engine. This study is based on more than twenty articles published in more than two decades. In actual days, applications of this device go from the most sensitive sensor to measure magnetic flux, called S.QU.I.D. (from Superconducting Quantum Interference Device) to quantum bits. A unit cell of a JJ, with a cost of about a few hundred dollars allows the availability of a magnetometer with a cost of about one million dollars to a quantum computer with cost of about ten million dollars. The Josephson junction is an old quantum engine for a rising new world with incredible disruptive technological possibilities.The article is organized as follows: in section 1 we give a short introduction to the subject; section 2 describes the physics of the Josephson effect and the engineering of the Josephson junction; in section 3 we show the magnetic, transport and thermal properties of 2D-JJA; and in section 4 we show the relation between JJA and superconducting granular systems, in particular those related to High-Temperature Superconductors (HTS).
