One of the biggest puzzles in quantum theory today is to show how the well-studied properties of a few particles translate into a statistical theory from which new macroscopic quantum thermodynamic laws emerge. This challenge is addressed by the emerging field of quantum thermodynamics which has gro ...

Quantum States of Neutrons in the Gravitational Field
... For a neutron, a kinetic energy of 100 neV corresponds to a velocity v ≈ 2.2 m/s. This means that slow neutrons may be significantly accelerated or decelerated by falling or raising in the Earth’s gravitational field. It is noteworthy that gravity can easily be the strongest long-ranged interaction ...
