Perspective: Fifty years of density-functional theory in chemical physics
... The intuitive origins of density-functional theory predate the seminal 1964–1965 Hohenberg-Kohn-Sham papers3, 4 by many decades. Thomas,10 Fermi,11 and Dirac12 imagined that the kinetic and exchange energies of systems of many electrons could be locally modeled by their uniform electron gas energy d ...

Quantum gauge theory simulation with ultracold atoms
... The study of ultracold atoms constitutes one of the hottest areas of atomic, molecular, and optical physics and quantum optics. The experimental and theoretical achievements in the last three decades in the control and manipulation of quantum matter at macroscopic scales lead to the so called third ...

... observation of vortices had been limited to small arrays (up to 11 vortices), both in liquid He [3] and more recently in rotating gaseous Bose-Einstein condensates (BEC) [4, 5]. We have observed the formation of highly-ordered vortex lattices in a rotating Bose-condensed gas [6]. They were produced ...

Entanglement Spectrum in the Fractional Quantum Hall Effect
... In particular the FQHE exhibits a new type of order different from the classical or quantum orders that can be described by the paradigm of Landau’s symmetry breaking theory. This new type of order is robust upon local perturbations and cannot be described by a symmetry or a broken symmetry. In part ...
