Collective excitations and supersolid behavior of bosonic atoms inside two crossed optical cavities

We discuss the nature of symmetry breaking and the associated collective excitations for a system of bosons coupled to the electromagnetic field of two optical cavities. For the specific configuration realized in a recent experiment at ETH [ 1 , 2 ], we show that, in absence of direct intercavity sc...
