Coherent Plasma in a Lattice
L. Gamberale, G. Modanese
We present a fully second-quantized calculation showing the emergence of spontaneous coherent configurations of the electromagnetic field in interaction with charged bosons in a re…
Quantum metrics with very low action in gravity
G. Modanese
We have run numerical simulations of Euclidean lattice quantum gravity for metrics which are time-independent and spherically symmetric. The radial variable is discretized as $r=hL…
Design of a test for the electromagnetic coupling of non-local wavefunctions
G. Modanese
It has recently been proven that certain effective wavefunctions in fractional quantum mechanics and condensed matter do not have a locally conserved current; as a consequence, the…
Time in quantum mechanics and the local non-conservation of the probability current
G. Modanese
In relativistic quantum field theory with local interactions, charge is locally conserved. This implies local conservation of probability for the Dirac and Klein-Gordon wavefunctio…
Electromagnetic coupling of strongly non-local quantum mechanics
G. Modanese
Although standard quantum mechanics has some non-local features, the probability current of the Schrödinger equation is locally conserved, and this allows minimal electromagnetic c…
Ultra-light and strong: the massless harmonic oscillator and its singular path integral
G. Modanese
In classical mechanics, a light particle bound by a strong elastic force just oscillates at high frequency in the region allowed by its initial position and velocity. In quantum me…
Generalized Maxwell equations and charge conservation censorship
G. Modanese
The Aharonov-Bohm electrodynamics is a generalization of Maxwell theory with reduced gauge invariance. It allows to couple the electromagnetic field to a charge which is not locall…
Gravity-Superconductors Interactions as a Possible Means to Exchange Momentum with the Vacuum
Giovanni Modanese
We report on work in progress in quantum field theory about possible interactions between coherent matter, i.e. matter described by a macroscopic wave function or a classical field…
A comparison between the YBCO discharge experiments by E. Podkletnov and C. Poher, and their theoretical interpretations
Giovanni Modanese
Experimental results recently published by C. Poher provide independent evidence for the anomalous radiation emitted from YBCO electrodes under short, intense current pulses previo…
Velocity requirements for causality violation
Giovanni Modanese
We re-examine the "Regge-Tolman paradox" with reference to some recent experimental results. It is straightforward to find a formula for the velocity v of the moving system require…
Anomalous gravitational vacuum fluctuations which act as virtual oscillating dipoles
Giovanni Modanese
In this work we review some concepts developed over the last few years: that the gravitational vacuum has, even at scales much larger than the Planck length, a peculiar structure,…
Evolution of the IGG concept at IGF from 2004 to 2007
G. Modanese
IGG is the acronym for Impulse Gravity Generator, a device developed by E. Podkletnov in 1997-2003 for generating high-voltage discharges through YBCO electrodes. According to Podk…
Conditions for stimulated emission in anomalous gravity-superconductors interactions
G. Modanese, T. Junker
Several authors have studied the generation of gravitational fields by condensed-matter systems in non-extreme density conditions. General Relativity and lowest-order perturbative…
The vacuum state of quantum gravity contains large virtual masses
Giovanni Modanese
In the functional integral approach to quantum gravity, the quantum configurations are usually treated to order hbar through a stationary phase approximation around the saddle poin…
Effect of the Vacuum Energy Density on Graviton Propagation
Giovanni Modanese, Giorgio Fontana
It is known that the value L of the vacuum energy density affects the propagation equation for gravitons: A mass term appears in the propagation equation, such that m^2=-L. As a co…
Evaluation of an Impulse Gravity Generator Based Beamed Propulsion Concept
Giovanni Modanese, Chris Y. Taylor
This paper analyzes the suitability of a beamed propulsion concept having properties consistent with the impulse gravity generator described by Podkletnov et al. [physics/0108005].…
Investigation of high voltage discharges in low pressure gases through large ceramic superconducting electrodes
Evgeny Podkletnov, Giovanni Modanese
A device has been built and tested, in which a ceramic superconducting cathode and a copper anode cause electrical discharges in low pressure gases, at temperatures between 50 and…

Evgeny Podkletnov, Giovanni Modanese
The detection of apparent anomalous forces in the vicinity of high-Tc superconductors under non equilibrium conditions has stimulated an experimental research in which the operatin…
Gravitational Anomalies by HTC Superconductors: a 1999 Theoretical Status Report
G. Modanese
In this report we summarize in an informal way the main advances made in the last 3 years and give a unified scheme of our theoretical work. This scheme aims at connecting in a con…
