    On weak links fed with irreversible currents

    We briefly discuss the usual time-reversible descriptions for displacement- and real-current-fed small-capacitance weak links. Many real laboratory current sources deliver charge in an intrinsically irreversib...

    Microscopic views of simple macroscopic quantum behaviour

    For simple-model microscopic systems, we discuss whether (or not) potentially observable macroscopic quantum behaviour can arise, making explicit two criteria which must be satisfied for this to be possible. W...

    Comments on small capacitors

    We discuss the concept of an ultrasmall capacitor and the experimental probing of such objects.

    Adding dissipation to the Schrödinger equation from the quantum-potential viewpoint

    We discuss methods of adding dissipation to the Schrödinger equation in light of the quantum-potential interpretation of quantum mechanics. This favors nonlinear equations in general and Kostin's Schrödinger-L...

    The response of a superconducting weak-link ring to external adiabatic noise

    We discuss the response of a superconducting weak-link ring to externally applied adiabatic noise and show that this can be used as a probe of the low-lying energy eigenstates of the ring. We compare the obser...

    Coherent quantum oscillation trajectories

    We discuss coherent oscillations in the quantum potential view of quantum mechanics, giving examples for both a superposition of “position” states, and a superposition of “momentum” states.

    Coupled quantum object dynamics

    We discuss the dynamical behaviour of coupled quantum objects. This leads to a novel method of observing macroscopic quantum behaviour.

    Electromagnetic duality in quantum circuits

    To illustrate the duality between electric and magnetic views of quantum circuits, we compare and contrast the origins of the Josephson frequency and the current bias frequency in each case.

    Theoretical polarizability of small ferro-electric crystal domains exibiting quantum tunnelling

    The implications of macroscopic quantum tunnelling in small single-domain ferro-electric crystals is discussed in terms of the resulting static differential polarizability.

    Schwinger renormalization group equations of state in circuits with classical electrodynamic noise

    We discuss the effective noise temperatureT * of a low-temperature circuit in terms of the Schwinger action principle formulation of the quantum Brownian-motion problem, and in the limit ω≪k B T */h. Within this ...
