How small can a laser be made? What characteristic properties must a device possess to
still be called a laser? How can one prove laser action in the limiting cases of single-emitter …

Gain-dissipative systems of various physical origin have recently shown the ability to act as
analogue minimisers of hard combinatorial optimisation problems. Whether or not these …
