Strong zero modes in a class of generalized Ising spin ladders with plaquette interactions (2019)
Journal Article

© 2019 American Physical Society. We study a class of spin-1/2 quantum ladder models with generalized plaquette interactions in the presence of a transverse field. We show that in certain parameter regimes, these models have strong zero modes respons... Read More about Strong zero modes in a class of generalized Ising spin ladders with plaquette interactions.

Localization in spin chains with facilitation constraints and disordered interactions (2019)
Journal Article

Quantum many-body systems with kinetic constraints exhibit intriguing relaxation dynamics. Recent experimental progress in the field of cold atomic gases offers a handle for probing collective behavior of such systems, in particular for understanding...

Quantum accelerated approach to the thermal state of classical all-to-all connected spin systems with applications to pattern retrieval in the Hopfield neural network (2019)
Journal Article

We explore the question as to whether quantum effects can yield a speedup of the nonequilibrium evolution of fully connected quadratic spin models towards a classical thermal state. In our approach we exploit the fact that the thermal state of a spin...

Synthetic lattices, flat bands and localization in Rydberg quantum simulators (2019)
Journal Article

© 2019 IOP Publishing Ltd. The most recent manifestation of cold Rydberg atom quantum simulators that employs tailored optical tweezer arrays enables the study of many-body dynamics under so-called facilitation conditions. We show how the facilitatio... Read More about Synthetic lattices, flat bands and localization in Rydberg quantum simulators.

Discrete time crystals in the absence of manifest symmetries or disorder in open quantum systems (2019)
Journal Article

We establish a link between metastability and a discrete time-crystalline phase in a periodically driven open quantum system. The mechanism we highlight requires neither the system to display any microscopic symmetry nor the presence of disorder, but...
