Although this method is often used to produce other gases, like nitrogen and oxygen, it is rarely used to produce helium. The Manufacturing Process Helium is usually produced as a byproduct of natural gas processing. Natural gas contains methane and other hydrocarbons, which are the principal ...

His theory was inspired by the less common isotope of helium, namely 3He4, the first experimental platform for testing the theory. Decades later, the theory was also applied to strongly correlated metals, known as heavy-fermion systems5. Leggett, reviewing liquid 3He6, writes that it is “...
But I have a unusual passion hobby, which is to take helium balloons, toy, helium balloons, and assemble them in massive clusters for manned flight.但我有个不同寻常的富有激情的爱好——玩具氦气球，把大量的氦气球组合起来用于载人飞行。These are loons that were never intended to support manned ...
as is seen in Fig.3a. When thermal conductivity due to quasiparticles becomes small, the other remaining mechanism becomes important, namely conductivity due to collective excitations, sound. Using Landau’s own words, “sonic excitations in the gas of quasi-particles (phonons of the “zeroth soun...
