Tunable Multiband Geometry and Fractional Phases in Higher Vortexable Systems
Xiaohan Wan, Siddhartha Sarkar, Ting Cao +3
Higher vortexability is often viewed as a route to topological flat bands with higher-Landau-level-like quantum geometry. Here we emphasize a complementary perspective: it provides…
Self-organized Floquet band geometry in cavity-driven quantum materials
Christopher Yang, Gil Refael, Mark S. Rudner +1
Floquet engineering has emerged as a powerful route to dynamically control band structure and topology in quantum materials, but most implementations rely on externally imposed las…
A Lieb-Robinson bound for open quantum systems with memory
Rahul Trivedi, Xiehang Yu, Mark Rudner
We consider a general class of spatially local non-Markovian open quantum lattice models, with a bosonic environment that is approximated as Gaussian. Under the assumption of a fin…
Vari-Cool: a non-unitary quantum variational protocol for simulated cooling
Jeffrey Z. Song, Gilad Kishony, Erez Berg +1
We introduce a variational approach for preparing low energy states of arbitrary target Hamiltonians. The protocol is defined in terms of a repeated cycle consisting of p layers of…
Topological excitations at time vortices in periodically driven systems
Gilad Kishony, Ori Grossman, Netanel Lindner +2
We consider two-dimensional periodically driven systems of fermions with particle-hole symmetry. Such systems support non-trivial topological phases, including ones that cannot be…
Efficiently preparing chiral states via fermionic cooling on bosonic quantum hardware
Gilad Kishony, Mark S. Rudner, Erez Berg
Simulating many-body systems is one of the most promising applications of near-term quantum computers. An important open question is how to efficiently prepare the ground states of…
