"Millikan oil drops" are drops of superfluid helium coated with electrons, and levitated in a strong, inhomogeneous magnetic field. When the temperature of the system becomes very low compared to the cyclotron gap energy, the system remains in its quantum ground state. Two such levitated charged drops can have their charge-to-mass ratio critically adjusted so that the forces of gravity and electricity between the drops are in balance. Then it is predicted that the amount of scattered… Expand

Dynamical Casimir effect and the possibility of laser-like generation of gravitational radiation
In this paper, we address the question as to whether or not measurable sources for gravitational waves could possibly be made in the laboratory. Based on an analogy of the dynamical Casimir effectExpand
A Gravitational Aharonov-Bohm Effect, and Its Connection to Parametric Oscillators and Gravitational Radiation
A thought experiment is proposed to demonstrate the existence of a gravitational, vector Aharonov-Bohm effect. We begin the analysis starting from four Maxwell-like equations for weak gravitationalExpand
Method of images applied to an opto-mechanical Fabry-Perot resonator
The method of images, when applied to an opto-mechanical Fabry-Perot resonator with a heavy, charged mirror, and a light, charged mirror that can be driven into motion, reveals that the highest orderExpand
A new approach to ultrasensitive gravitational wave detection
We suggest here a method to detect gravitational waves (GW) different from the interferometric approach. It is based on two critical steps: conversion of the GW action into rotational motion andExpand


The interface between quantum mechanics and general relativity
The generation, as well as the detection, of gravitational radiation by means of charged superfluids is considered. One example of such a “charged superfluid” consists of a pair of Planck-mass-scale,Expand
Do mirrors for gravitational waves exist
Abstract Thin superconducting films are predicted to be highly reflective mirrors for gravitational waves at microwave frequencies. The quantum-mechanical non-localizability of the negatively chargedExpand

Time and Matter in the Interaction Between Gravity and Quantum Fluids:. are There Macroscopic Quantum Transducers Between Gravitational and Electromagnetic Waves?
Measurements of the tunneling time are briefly reviewed. Next, time and matter in general relativity and quantum mechanics is examined. In particular, the question arises: How does gravitationalExpand
Measurement of Gravitomagnetic and Acceleration Fields around Rotating Superconductors
It is well known that a rotating superconductor produces a magnetic field proportional to its angular velocity. The authors conjectured earlier, that in addition to this so‐called London moment, alsoExpand

Conceptual tensions between quantum mechanics and general relativity: Are there experimental consequences, e.g., superconducting transducers between electromagnetic and gravitational radiation?
One of the conceptual tensions between quantum mechanics (QM) and general relativity (GR) arises from the clash between the spatial nonseparability of entangled states in QM, and the complete spatialExpand
Introduction to Superconductivity
We have seen how the conductivity of a metal is limited by collisions, which determine the electron mean free path. After a collision, an electron completely loses all memory of its quantum state asExpand
The Quantum Hall Effect
The integral quantum Hall effect was discovered in 1980 by Klaus von Klitzing, Michael Pepper, and Gerhardt Dordda. Truly remarkably, at low temperatures (~ 4 K), the Hall resistance of a twoExpand
