Donglai's Summer Project

• We are interested the behavior of electrons inside a magnetic or photon field.
• The spin states of an electron can be used to store information. Knowing how fast these spin states decay in background radiation is essential in designing future quantum storage devices.
• A pure quantum system is described by wave function and its time evolution governed by the Schrodinger equation. The Schrodinger equation is well studied and many methods exist for solving it.
• However, electrons inside a magnetic or photon field are not in pure states thus cannot be described by a wave function. We use density matrix.
• The time evolution of a density matrix is governed by the Liouville equation. My work is focused on solving the Liouville equation for system of two electrons in a magnetic or photon field.
