- Abstract: The combined effect of disorder and interactions is central to the richness
of condensed matter physics and can lead to novel quantum states such as the
Bose glass phase in disordered bosonic systems. Here, we report on the
experimental realisation of the two-dimensional Bose glass using ultra-cold
atoms in an eight-fold symmetric quasicrystalline optical lattice. By probing
the coherence properties of the system, we observe a Bose glass to superfluid
transition and map out the phase diagram in the weakly interacting regime.
Moreover, we reveal the non-ergodic nature of the Bose glass by probing the
capability to restore coherence. Our observations are in good agreement with
recent quantum Monte Carlo predictions and pave the way for experimentally
testing the connection between the Bose glass, many-body localisation, and
glassy dynamics more generally.

Disordered potentials fundamentally alter the transport properties and coherence of quantum systems.
In interacting bosonic systems, a Bose glass is expected to emerge at low energies as an insulating yet compressible state without long-range phase coherence.
We utilize ultracold bosonic atoms in a quantum-gas microscope to probe the emergence of the Bose-glass phase in a two-dimensional square lattice.

Two non-identical quantum emitters, when placed within a cavity and coherently excited at the two-photon resonance, can reach stationary states of nearly maximal entanglement.
We show that this mechanism is merely one among a complex family of phenomena that can generate both stationary and metastable entanglement when driving the emitters at the two-photon resonance.
