The “magnetic” type of these particles is a theorized alternative to computer bits. For 10 points each:
[10h] Name these topologically-protected soliton particles that were initially introduced to describe nucleons.
ANSWER: skyrmions [accept magnetic skyrmions]
[10e] Magnets without the “centro-” form of this property can stabilize magnetic skyrmions. s orbitals have the “spherical” form of this property with respect to the nucleus because electron density only depends on distance from the nucleus.
ANSWER: symmetry [or symmetrical; accept (non)centrosymmetrical, (non)centrosymmetry, spherical symmetry, or spherically symmetrical]
[10m] The skyrmion model of the nucleon reproduces the standard one-pion exchange potential, which improves on this spherically-symmetric screened Coulomb potential. Named for a physicist, it varies like “e to the minus kr all over r.”
ANSWER: Yukawa potential
