Scattering of second sound waves by quantum vorticity.
A new method of detection and measurement of quantum vorticity by scattering second sound off quantized vortices in superfluid Helium is suggested. Theoretical calculations of the relative amplitude of the scattered second sound waves from a single quantum vortex, a vortex ring, and bulk vorticity are presented. The relevant estimates show that an experimental verification of the method is feas...
متن کاملQuantum Nature of the Big Bang in Loop Quantum Cosmology
A central feature of general relativity is that gravity is encoded in the very geometry of space-time. Loop quantum gravity is a non-perturbative approach to unifying general relativity with quantum physics while retaining this interplay between geometry and gravity [1, 2, 3]. There is no background space-time; matter as well as geometry are ‘quantum from birth’. Effects of quantum geometry are...
متن کاملQuantum nature of laser light
All compositions of a mixed state density operator are equivalent for the prediction of the probabilities of future outcomes of measurements. For retrodiction, however, this is not the case. The retrodictive formalism of quantum mechanics provides a criterion for deciding that some compositions are fictional. Fictional compositions do not contain preparation device operators, that is, operators...
متن کاملOn Quantum Nature of Gravity
In this paper, starting from a new unified formalism of quantum mechanics and thermodynamics developed in Agung Budiyono, ArXiv:quant-ph/0512235 and quant-ph/0601212, we shall derive Einstein general relativity. Gravity will be shown to be not as ”fundamental physics”, but as ”emergent phenomena” of quantum physics, after the latter is decoded in term of geometrical language. In particular, the...
متن کاملQuantum nature of cosmological bounces
Several examples are known where quantum gravity effects resolve the classical big bang singularity by a bounce. The most detailed analysis has probably occurred for loop quantum cosmology of isotropic models sourced by a free, massless scalar. Once a bounce has been realized under fairly general conditions, the central questions are how strongly quantum it behaves, what influence quantum effec...
