Superconducting Memristors

Abstract: In his original work Josephson predicted that a phase-dependent conductance should be present in superconducting tunnel junctions, an effect difficult to detect, mainly because it is hard to single it out from the usual non-dissipative Josephson current. We propose a solution for this problem that consists in using different superconducting materials to realize the two junctions of a superconducting interferometer. According to the Ambegaokar-Baratoff relation the two junctions have different conductances if t… Show more

“…In Ref. [13], timedependent density-matrix renormalization-group simulations of the collision of 1D Bose gases at T = 0 found reasonable agreement with the hydrodynamic approximation, although the latter failed to predict short-wavelength dynamics such as shock waves. An alternative approximate approach, based on the conservation of Lieb-Liniger rapidities, has been applied to describe the free-expansion dynamics of a T = 0 1D gas [15] and was able to reproduce the hydrodynamic results for both weak and strong interactions.…”

“…Second, the very notion of local thermalization, required for the validity of collisional hydrodynamics of normal fluids, is questionable due to the underlying integrability of the uniform 1D Bose gas model [9]. Despite these reservations, the hydrodynamic approach has already been applied to zero-temperature (T = 0) dynamics of 1D Bose gases in various scenarios [10][11][12][13][14][15] (for related experiments, see [16][17][18]). The comparison of hydrodynamic predictions with exact theoretical results is challenging.…”

“…Indeed, it has been argued that the initial state can affect this scenario, in particular if it breaks some symmetries of the Hamiltonian governing the subsequent evolution which tend to be recovered in a statistical ensemble such as thermal or GGE. The case that has been most largely studied is that of a non-translationally invariant initial state generically referred to as inhomogeneous quenches [67,68,69,70,71,72,73,74]. Among the inhomogeneous quenches, a particularly relevant one which has been already experimentally realized (also in one dimension [8,9]) is the non-equilibrium dynamics of a gas released from a parabolic trapping potential.…”

“…The microcanonical formalism is particularly suitable for ultra-cold atoms, which are accurately modeled as isolated quantum systems. In this respect, the formalism has already been developed to study transport phenomena in these systems [23][24][25][26][27][28].…”
