What is Quantum Thermodynamics?
... The state of a system may change with time either spontaneously due to its internal dynamics or as a result of interactions with other systems, or both. Systems that cannot induce any effects on each other’s state are called isolated. Systems that are not isolated can influence each other in a number ...

Quantum Field Theory and Representation Theory

This is non-zero when λ is related to a λ′ in the dominant Weyl chanber by action of an element of the Weyl group. In some sense irreducibl ...

Hydrogenic (or hydrogen-like) atoms are ions which have a nucleus composed of Z protons (and Z neutrons), and a single electron (e.g. He+ , Li++ , Be 3+ ).
