High quality-factor (Q) optical resonators are a key component for ultra-narrow linewidth
lasers, frequency stabilization, precision spectroscopy and quantum applications. Integration …

Theoretical models of critical mass have shown how minority groups can initiate social
change dynamics in the emergence of new social conventions. Here, we study an artificial …

Exceptional points (EPs) are special spectral degeneracies of non-Hermitian Hamiltonians
that govern the dynamics of open systems. At an EP, two or more eigenvalues, and the …

Spectrally pure lasers, the heart of precision high-end scientific and commercial
