“Regge-like” relations for stable (non-evaporating) black holes
Foundations of Physics Letters - Tập 7 - Trang 167-179 - 1994
Within a purely classical formulation of “strong gravity,” we associated hadron constituents (and even hadrons themselves) with suitable stationary, axisymmetric solutions of certain new Einsteintype equations supposed to describe the strong field inside hadrons. Such equations are nothing but Einstein equations—with cosmological term—suitably scaled down. As a consequence, the cosmological consta...... hiện toàn bộ
The Einstein Constant c in Light of Mach's Principle. Cosmological Applications
Foundations of Physics Letters - - 2003
In a recent paper, O. Costa de Beauregard shows that Mach's conjecture can be expressed by the equation U=c
2 (U denoting the cosmological potential). This result leads us to a geometrical interpretation of Einstein's constant c (the so-called velocity of light) which appears as intimately connected to the expansion of the universe. We also present some cosmological consequences of that interpreta...... hiện toàn bộ

Dissipation and reduction effects of spontaneous localization on superconducting states
Foundations of Physics Letters - Tập 8 - Trang 105-125 - 1995
The problem of quantum measurement is briefly recalled with particular reference to theories of reduction as a real physical process. The spontaneous localization models for systems containing identical particles are described and the choice of the model when several kinds of particles are present is discussed. Dissipation and reduction effects induced by spontaneous localization in superconductin...... hiện toàn bộ
Thermodynamics and Preferred Frame
Foundations of Physics Letters - - 2001
The Lorentz covariant statistical physics and thermodynamics is formulated within the preferred frame approach. The transformation laws for geometrical and mechanical quantities such as volume and pressure as well as the Lorentz-invariant measure on the phase space are found using Lorentz transformations in absolute synchronization. Next, the probability density and partition function are investig...... hiện toàn bộ
Analytic Results for Gaussian Wave Packets in Four Model Systems: II. Autocorrelation Functions
Foundations of Physics Letters - Tập 17 - Trang 645-661 - 2004
The autocorrelation function, A(t), measures the overlap (in Hilbert space) of a time-dependent quantum mechanical wave function, ψ(x, t), with its initial value, ψ(x, 0). It finds extensive use in the theoretical analysis and experimental measurement of such phenomena as quantum wave packet revivals. We evaluate explicit expressions for the autocorrelation function for time-dependent Gaussian sol...... hiện toàn bộ
Arithmetic of the Integer Quantum Hall Effect
Foundations of Physics Letters - Tập 11 - Trang 561-571 - 2014
The integer quantum Hall effect (IQHE) is analysed, considering the degeneracies of localized and extended states separately. Occupied localized and extended states are counted, and their variation is studied as a function of magnetic field. The number of current-carrying electrons is found to have a saw-tooth variation with magnetic field. The analysis addresses certain basic questions in the IQH...... hiện toàn bộ
On quantum field theory with invariant parameter
Foundations of Physics Letters - Tập 7 - Trang 551-576 - 1994
The Dirac-type quantum theory with invariant parameter is formulated in a way such that for particle states with positive frequencies and antiparticle states with negative frequencies the energy densities and probability densities all are positive. This consistent formulation of single-particle quantum theory for spin-1/2 is used as a basis for second quantization. The inclusion of an invariant pa...... hiện toàn bộ
Quantum Spectrum of Some Anharmonic Central Potentials: Wave Functions Ansatz
Foundations of Physics Letters - Tập 16 - Trang 357-367 - 2003
Based on the ansatz to the wave functions, the quasi-exact solutions of the 2D Schrödinger equation with some anharmonic potentials are reviewed and analyzed if admitting restrictions on the parameters of the potential and the angular momentum m. These potentials are taken as the screened Coulomb potential V(r)=a/r+b/(r+λ), the singular one-fraction power one V(r)=ar
