On applying Quantum Mechanics to the problem of a particle bound in an external gravitational potential, we find the following results, which violate one's classical conception of the principle of weak equivalence: radii, frequencies, etc., depend on the mass of the bound particle; the binding energy has the wrong mass dependence; inertial forces do not look like gravitational forces; and there are mass-dependent interference effects. These inconsistencies disappear in the classical limit, which must be approached in a particular manner.
The conclusion is reached that the classical statements one can make using weak equivalence have no direct quantum analog and thus the principle is somewhat irrelevant in discussing low-lying quantum states.

## Abstract The physical problem of the equivalence of certain partition function in statistical mechanics leads to the following mathematical problem: Under what conditions is the logarithm of a LaplaceβStieltjes transform of the soβcalled microcanonical partition function equal to a Legendre tran
The concept and the formalization of the arrival time in quantum mechanics are discussed. Different approaches based on trajectories, quantization rules, time operators, phase-space techniques, renewal equations or operational procedures are reviewed or proposed. Open questions and loose ends are po
An expression for the quantum time of arrival based on the current density is discussed and justified operationally by means of complex potentials that absorb the incoming wave in a finite distance without reflection or transmission. Previous arguments denying the possibility of defining the time of
A highly entertaining exploration of the complicated science of quantum mechanics made easy to understand by way of pop culture. As a young science fiction fan, physicist James Kakalios marveled at the future predicted in the pulp magazines, comics, and films of the β50s and β60s. By 2010, he was su
