Moiré superstructures are currently intensely studied in solid state physics, in connection with the generation of nontrivial flat bands that lead to exotic many-body ground states. The authors show here that moiré flatbands can be conveniently engineered and exploited in a very different space: the one defined by the number of transported charges in superconducting quantum circuits. In particular, all circuit designs proposed require only very basic and experimentally highly accessible materials and structures. The authors thus establish quasiperiodic circuit QED as a promising new research area, exploring deep connections between quantum transport and recent developments in condensed matter physics.

The chiral limit of twisted bilayer graphene, where Landau level-like states form an “ideal” flat band, has been central to understanding fractional Chern insulators in analogy with Landau level physics. The authors show here that even in this limit, fluctuating quantum geometry strongly breaks particle-hole symmetry, favoring a Fermi liquid at 2/3 filling and distorting Laughlin-like states at 1/3 filling. With Coulomb interactions, the system hosts trivial charge density waves at 1/4 filling and a quantum anomalous Hall crystal at 3/4 filling — phases absent in the lowest Landau levels.

Strong-to-weak spontaneous symmetry breaking meets average symmetry-protected topological order

The authors uncover here a new quantum phase — the double average symmetry-protected topological (ASPT) phase — that arises uniquely in open quantum systems, where symmetry breaking and topological order coexist. Using the imaginary-time Lindbladian formalism, they establish a rich phase diagram featuring distinct gapless phases and topological triple points. This work highlights how environmental interactions can lead to novel quantum phenomena with no analog in closed systems.

Ultrafast dynamics of a fermion chain in a terahertz field-driven optical cavity

The authors study here ultrafast dynamics in a fermion chain within a terahertz laser-driven optical cavity, coupled to infrared-active phonons. Realistic photon loss in low-quality cavities blocks first-order phase transitions and polariton formation. In high-quality cavities, strong laser drives sustain transitions in the lower phonon-polariton branch. Weak laser fields restore polariton symmetry but fail to trigger transitions. These findings highlight experimentally feasible approaches to manipulate quantum phases and achieve ultrafast switching through cavity-dressed electron-phonon interactions for controlling laser-driven quantum materials.
