Abstract Random Lasers (RLs) and Random Fiber Lasers (RFLs) have been the subject of
intense research since their first experimental demonstration in 1994 and 2007, respectively …

This is an extended version of my Nobel Lecture, delivered on December 8, 2021. I will
recall the genesis of the concept of multiple equilibria in natural sciences. I will then describe …

Quantum and classical physics can be used for mathematical computations that are hard to
tackle by conventional electronics. Very recently, optical Ising machines have been …

The optics of correlated disordered media is a conceptually rich research topic emerging at
the interface between the physics of waves in complex media and nanophotonics. Inspired …

Scattering of light by disordered structures is a common phenomenon in our daily life. For
many scientific applications, scattering is often treated as a detrimental effect. However …

Random lasing—for which disorder is exploited to enhance stimulated emission—has
emerged as a paradigmatic phenomenon of complex lasers. Random lasers feature unique …

Conventional computing architectures have no known efficient algorithms for combinatorial
optimization tasks such as the Ising problem, which requires finding the ground state spin …

Recent studies on exceptional points (EPs) in non-Hermitian optical systems have revealed
unique traits, including unidirectional invisibility, chiral mode switching and laser self …

We describe simulations of the quantum dynamics of a confocal cavity QED system that
realizes an intrinsically driven-dissipative spin glass. A close connection between open …

The inability of conventional electronic architectures to efficiently solve large combinatorial
problems motivates the development of novel computational hardware. There has been …
