Bottom: First excited state — the most positive point is far from the most negative point to minimize the gradient energy. Roughly, the slope is reduced from d Φ 0 /dx to (say for simplicity) zero, so the kinetic part of the … WebJun 19, 2014 · A superfluid, really, composed of fundamental objects we may not have discovered yet.

Fugu-MT 論文翻訳(概要): Anti-Drude Metal of Bosons
WebWe present a first study of the multifractal properties of the ground state of the Bose–Hubbard Hamiltonian in Fock space. Numerical simulations of system sizes up to L = 10 at unit filling suggest that multifractality is present for all values of the bosonic interaction strength. Moreover, the analysis of the generalised fractal dimensions for different … WebAbstract: In the absence of frustration, interacting bosons in the ground state exist either in the superfluid or insulating phases. Superfluidity corresponds to frictionless flow of the matter field, and in optical conductivity is revealed through a distinct $\delta$-functional peak at zero frequency with the amplitude known as the Drude weight. cl140fdrfw マキタ

WebIn condensed matter physics, a Bose–Einstein condensate (BEC) is a state of matter that is typically formed when a gas of bosons at very low densities is cooled to temperatures very close to absolute zero (−273.15 °C or −459.67 °F). Under such conditions, a large fraction of bosons occupy the lowest quantum state, at which point microscopic quantum … cl1251とは
