Feynman used path integrals to map a quantum system onto "polymers" to create a model of these entities.
Feynman used path integrals to map a quantum system onto "polymers" to create a model of these entities. One article studied the transition of one of these into a substance that does not conduct electricity despite classical predictions, called a Mott insulator. When rotating around a point, it can only move in whole number multiples of a minimum velocity, a property known as quantized vortices. All atoms of a material in this phase occupy the (*) same quantum state, and materials of this type can flow over the walls of a beaker without an external start to their motion. For 10 points, name this state in which a substance loses all viscosity, notably reached by helium near 2 Kelvin.
