【摘要】：我們通過精確鎖定Feshbach共振線圈中的電流,獲得了穩(wěn)定度接近10-5的Feshbach共振磁場。利用RF射頻譜和原子共振損失譜精確地測量了超冷6 Li費(fèi)米原子氣體的窄Feshbach共振,研究了該Feshbach共振的相互作用和原子氣體的能量依靠關(guān)系,測量了原子內(nèi)態(tài)相互作用和密度所導(dǎo)致的射頻躍遷的散射碰撞頻移。這種能量依靠的相互作用的費(fèi)米原子氣體具有重要的意義,可以產(chǎn)生新奇的超流,用來模擬中子星物質(zhì)的態(tài)方程。
[Abstract]:By accurately locking the current in the Feshbach resonance coil, we obtain a Feshbach resonance magnetic field with stability close to 10-5. The narrow Feshbach resonance of ultracold 6 Li Fermi atomic gas has been accurately measured by RF radio frequency spectrum and atomic resonance loss spectrum. The interaction between the Feshbach resonance and the energy dependence of the atomic gas has been studied. The scattering collision frequency shift of the radio frequency transition caused by the internal state interaction and density has been measured. This energy-dependent interacting Fermi atomic gas is of great significance and can produce novel superflows that can be used to simulate the equation of state of neutron star matter.
