The Exciton Bohr Radius – Where Quantum Magic Happens: A key factor that determines just how small is "small enough" for a particle to enter the zero-dimensional realm is something physicists term the ...

Thus, Scientist in China explored a class of peculiar polaritons, named plasmon-exciton polaritons ... as the polariton nonlinearity scales with the exciton Bohr radius, ...

The normal size of an exciton in a large (bulk) crystal, expressed as an exciton Bohr radius, provides an approximate dimension for the onset of quantum-confinement effects.

Nonlinear exciton polaritons in TMDs microcavities provide a versatile platform for ... which is more practical considering the extremely small Bohr radius and a sub-micrometer transport ...
