Coconut soup sliced, chopped or shredded. Green coconut fruit from young coconuts can also be used to prepare coconut soup, and coconut water and coconut oil are sometimes used as ingredients. Many various coconut soups exist in the world, with myriad ingredients used. Coconut soup is sometimes prepared in combinations using other ingredients, such as chicken, potato, or curry. It can be served as a hot or cold soup. "Sopito" is a common fish soup or fish chowder in Aruba and Curaçao of the Lesser Antilles. The dish uses coconut milk and salt-cured meat as main ingredients. Coconut water is also often
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)
