Quantum mechanical approaches to the virial S.LeBohec
... Department of Physics and Astronomy, University of Utah, Salt Lake City, UT 84112, USA (Dated: June 30th 2015) In this note, we approach the virial from a standard quantum mechanics point of view. Section 1 reviews the classical virial theorem. Section 2 reviews the Ehrenfest theorem as we will use ...

Introduction to loop quantum gravity
... The quantum nature of three of the four forces, electromagnetism, weak and strong interactions, suggest that gravitational force too should have quantum properties at Planck scales. Loop quantum gravity (LQG) is an attempt to quantise gravity in a non-perturbative and background independent way. Thi ...
