King coconut King coconut King coconut ("Cocos nucifera") is a variety of coconut, native to Sri Lanka where it is known as Thembili (Sinhala: තැඹිලි). Sweeter than regular coconuts, there are several sub varieties of the king coconut-the most common being the "red dwarf" (kaha thambili, commonly referred to as gon thambili). The other variety is "ran thambili", a smaller variety containing about forty nuts in a bunch. The king coconut tree is shorter than coconut trees, and are found commonly growing wild in many areas of the country. King coconut water has been used in Ayurveda. One of the most common
Fermi liquid theory non-interacting fermions), and why other properties differ. Important examples of where Fermi liquid theory has been successfully applied are most notably electrons in most metals and Liquid He-3. Liquid He-3 is a Fermi liquid at low temperatures (but not low enough to be in its superfluid phase). Helium-3 is an isotope of helium, with 2 protons, 1 neutron and 2 electrons per atom. Because there is an odd number of fermions inside the nucleus, the atom itself is also a fermion. The electrons in a normal (non-superconducting) metal also form a Fermi liquid, as do the nucleons (protons and neutrons)
