Driven-dissipative systems are characterized by the appearance of steady-states. Upon parameter change, they can undergo dissipative phase transitions between different types of steady-states. One of the paradigmatic examples for a first order dissipative phase transition is the driven nonlinear single-mode optical resonator. I will report on the corresponding realization within an ultracold...

I present the relatively recent concept of first-order dissipative phase transitions that can occur in meso- and even microscopic quantum systems. One of the first examples of this phenomenology was the photon-blockade breakdown (PBB) effect, that occurs most simply in a coupled system of a bosonic mode and a qubit. For PBB, an abstract thermodynamic limit has been identified [1], where the...

Nitrogen-vacancy (NV) centers in diamond enable a variety of sensing applications ranging from measuring basic properties, such as temperature, pressure, strain, and external fields, down to detecting single cells, single molecules, or even single nuclear spins. Here, we present new opportunities for quantum sensing with shallow NV centers, i.e. located within 10 nm from the surface. First, we...
