Parametrically driving a quantum oscillator into exceptionality

Parametrically driving a quantum oscillator into exceptionality

Abstract The mathematical objects employed in physical theories do not always behave well. Einstein’s theory of space and time allows for spacetime singularities and Van Hove singularities arise in condensed matter physics, while intensity, phase and polarization singularities pervade wave physics. Within dissipative systems governed by matrices, singularities occur at …
