Quantum optics of ultracold quantum gases: open systems beyond dissipation (habilitation thesis)
Igor B. Mekhov
Quantum optics and ultracold gases are established fields, but they almost do not overlap: the quantum nature of light is typically neglected in works on ultracold atoms. In our wo…
Tuning the universality class of phase transitions by feedback: Open quantum systems beyond dissipation
D. A. Ivanov, T. Yu. Ivanova, S. F. Caballero-Benitez +1
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 univers…
Cavityless self-organization of ultracold atoms due to the feedback-induced phase transition
Denis A. Ivanov, Tatiana Yu. Ivanova, Santiago F. Caballero-Benitez +1
Feedback is a general idea of modifying system behaviour depending on the measurement outcomes. It spreads from natural sciences, engineering, and artificial intelligence to contem…
Quantum State Reduction by Matter-Phase-Related Measurements in Optical Lattices
Wojciech Kozlowski, Santiago F. Caballero-Benitez, Igor B. Mekhov
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…
Collective dynamics of multimode bosonic systems induced by weak quantum measurement
Gabriel Mazzucchi, Wojciech Kozlowski, Santiago F. Caballero-Benitez +1
In contrast to the fully projective limit of strong quantum measurement, where the evolution is locked to a small subspace (quantum Zeno dynamics), or even frozen completely (quant…
Incoherent quantum feedback control of collective light scattering by Bose-Einstein condensates
Denis A. Ivanov, Tatiana Yu. Ivanova, Igor B. Mekhov
It is well known that in the presence of a ring cavity the light scattering from a uniform atomic ensemble can become unstable resulting in the collective atomic recoil lasing. Thi…
