Observational Probabilities in Quantum Cosmology
... If Boltzmann brains dominate the measure for observations, one might ask, “So what?” Couldn’t it be that our observations are those of ordinary observers? Or couldn’t it be that our observations really are those of Boltzmann brains? However, since Boltzmann brain observations are produced mainly by ...

Three-axis measurement and cancellation of background magnetic
... observe critical features of the dynamics can in some cases be affected by magnetic field stability. Background magnetic fields are typically suppressed by passive magnetic shielding, or through measurement and active cancellation. The latter is often preferable in experiments that require good opti ...

In this realm there are not only thermal but also quantum fluctuations to deal with: even at absolute zero, where classical mechanics tells us that things should stand still, the uncertainty principle of quantum mechanics me ...

I will report on this question later. If the Bekenstein entropy were the whole thing, as far as the thermal ...

... The behavior of light in its interaction with matter was indeed a key problem of nineteenth-century physics. Planck was interested in the two theories that overlapped in this domain. The first was electrodynamics, the theory of electricity, magnetism, and light waves, brought to final form by James ...

The Hierarchy of Hamiltonians for a Restricted Class of Natanzon
... In particular, there have been studies within Supersymmetric Quantum Mechanics formalism. Cooper et al, [6], for instance, investigated the relationship between shape invariance and exactly analytical solvable potentials and showed that the Natanzon potential is not shape invariant although it has a ...

In this paper, we develop the concept of generalized uncertainty principle (G-UP) in the framework of linear and nonlinear optics. The gene ...

One can see also that, because a(t) is a concave function, the time between the singularity and the epoch t must always be less than the characteristic expansion time of the Universe, τH = 1/H ...
