Mekhov"] publication_types = ["2"] abstract = "A many-body atomic system coupled to quantized light is subject to weak measurement. Instead of coupling light to the on-site density, we consider the quantum backaction due to the measurement of matter-phase-related variables such as global phase coherence. We show how this unconventional approach opens up new opportunities to affect system evolution. We demonstrate how this can lead to a new class of final states different from those possible with dissipative state preparation or conventional projective measurements. These states are characterised by a combination of Hamiltonian and measurement properties thus extending the measurement postulate for the case of strong competition with the system’s own evolution." featured = false publication = "Scientific Reports 7, Article number: 42597" url_pdf = "https://www.nature.com/articles/srep42597" url_preprint = "https://arxiv.org/abs/1605.06000" doi = "10.1038/srep42597" +++
