We show that weak measurement leads to unconventional quantum Zeno dynamics with
Raman-like transitions via virtual states outside the Zeno subspace. We extend this concept …

We shift the paradigm of feedback control from the control of quantum states to the control of
phase transitions in quantum systems. We show that feedback allows tuning the universality …

We show that coupling ultracold atoms in optical lattices to quantized modes of an optical
cavity leads to quantum phases of matter, which at the same time possess properties of …

Light enables manipulating many-body states of matter, and atoms trapped in optical lattices
are a prominent example. However, quantum properties of light are completely neglected in …
