In condensed matter systems, an essential characteristic of electrons besides charge and spin is the orbital degree of freedom (ODoF). It plays a crucial role in understanding unconventional ...

Scientists have observed novel ergodicity-breaking in C60, a highly symmetric molecule composed of 60 carbon atoms arranged on the vertices of a 'soccer ball' pattern (with 20 hexagon faces and 12 ...

Chirality can be true or false, depending on the symmetry of dynamic propagation. Crystal lattice vibrations, called phonons, can also display chirality as has been shown in some two-dimensional ...
