Quantum Phase Transitions - Subir Sachdev
... Normally, we do this by raising temperature. The resulting phase transition between phases characterized by (1) and (2) is well understood, and described by the well-developed theory of classical phase transitions. This shall not be our interest here. Rather, we are interested in moving from magneti ...

Observing the proton off the light-cone
... In the IMF, the interactions between particles are Lorentz-dilated, and thus the systems appear as if interaction free: the proton is made of free partons. This is only true to a certain degree: leading twist. The so-called higher-twist contributions are sensitive to parton offshellness, transverse ...

Hydrogen atom
A hydrogen atom is an atom of the chemical element hydrogen. The electrically neutral atom contains a single positively charged proton and a single negatively charged electron bound to the nucleus by the Coulomb force. Atomic hydrogen constitutes about 75% of the elemental (baryonic) mass of the universe.In everyday life on Earth, isolated hydrogen atoms (usually called ""atomic hydrogen"" or, more precisely, ""monatomic hydrogen"") are extremely rare. Instead, hydrogen tends to combine with other atoms in compounds, or with itself to form ordinary (diatomic) hydrogen gas, H2. ""Atomic hydrogen"" and ""hydrogen atom"" in ordinary English use have overlapping, yet distinct, meanings. For example, a water molecule contains two hydrogen atoms, but does not contain atomic hydrogen (which would refer to isolated hydrogen atoms).
