Reply to "Comment on the comparative use of the electron density and its laplacian"

TL;DR: The authors show that the statements of the author are not justified and that he contradicts his own previous work, and that the author's statements of Bader do not justify his previous work.

A nanoscale experiment measuring gravity's role in breaking the unitarity of quantum dynamics

TL;DR: In this paper, a specific experimental set-up is proposed to identify the source of spontaneous symmetry breaking in a quantum to classical crossover, and the resulting dynamics are compared to those suggested by alternative scenarios for the quantum-to-classical crossover.

Berry phases for composite fermions: Effective magnetic field and fractional statistics

TL;DR: The quantum Hall superfluid is presently the only viable candidate for a realization of quasiparticles with fractional Berry phase statistics as discussed by the authors, and it has been shown that fractional statistics can be computed for composite fermions.

Quasi-particles and gauge invariance in the theory of superconductivity

TL;DR: In this paper, it was shown that the Meissner effect can be maintained in the quasi-particle picture by taking into account a certain class of corrections to the chargecurrent operator due to the phonon and Coulomb interaction.
Journal ArticleDOI

Random-Phase Approximation in the Theory of Superconductivity

TL;DR: In this paper, a generalization of the random-phase approximation of the theory of Coulomb correlation energy is applied to the superconductivity theory, and it is shown that most elementary excitations have the Bardeen-Cooper-Schrieffer energy gap spectrum, but there are collective excitations also.
Journal ArticleDOI

An Approximate Quantum Theory of the Antiferromagnetic Ground State

TL;DR: In this paper, the ground state energy of the Kramers-Heller theory of ferromagnetic ground states has been investigated and its properties were shown to lie within limits found elsewhere on rigorous grounds.
Journal ArticleDOI

Coherent Excited States in the Theory of Superconductivity: Gauge Invariance and the Meissner Effect

TL;DR: In this article, it was shown that the non-gauge-invariant terms in the Hamiltonian of Bardeen, Cooper, and Schrieffer have an effect on these states which vanishes in the weak coupling limit.
Journal ArticleDOI

Wave propagation in the early stages of aggregation of cellular slime molds.

TL;DR: A detailed theory of the velocity of propagation of the acrasin pulse responsible for the aggregation of some of the cellular slime molds is presented and it is shown that there is a critical density of amebae below which the waves cannot propagate.
