Exact Many-Body Ground States from Decomposition of Ideal Higher Chern Bands: Applications to Chirally Twisted Graphene Multilayers
Junkai Dong, Patrick J. Ledwith, Eslam Khalaf +2
Motivated by the higher Chern bands of twisted graphene multilayers, we consider flat bands with arbitrary Chern number with ideal quantum geometry. While bands differ fr…
Decoding Measurement-Prepared Quantum Phases and Transitions: from Ising model to gauge theory, and beyond
Jong Yeon Lee, Wenjie Ji, Zhen Bi +1
Measurements allow efficient preparation of interesting quantum many-body states with long-range entanglement, conditioned on additional transformations based on measurement outcom…
Landau-Forbidden Quantum Criticality in Rydberg Quantum Simulators
Jong Yeon Lee, Joshua Ramette, Max A. Metlitski +3
The Landau-Ginzburg-Wilson theory of phase transitions precludes a continuous transition between two phases that spontaneously break distinct symmetries. However, quantum mechanica…
