• Abstract: We investigate hard-core bosons in one dimension with quasiperiodic long-range interactions defined by V_ij = V0 cos(pi * alpha * i) cos(pi * alpha * j), where alpha = (sqrt(5) - 1)/2 is the inverse golden ratio. Large-scale quantum Monte Carlo simulations reveal incompressible density plateaus at incommensurate fillings tied to Fibonacci ratios. These plateaus feature emergent nonuniform density profiles and robust long-range correlations, as captured by the structure factor. Depending on filling and interaction strength, the system realizes either a quasi-solid phase with suppressed superfluidity, a quasi-supersolid phase where density order coexists with finite superfluid density, or a superfluid phase. Our results demonstrate that purely interaction-induced quasiperiodicity, without external potential or disorder, can stabilize novel quantum phases that simultaneously break translational symmetry and sustain quantum coherence.

The site-resolved measurement reveals the formation of domain walls within the commensurate ordered phase. As the experimental system sizes increase, we show that the wave vectors approach a continuum of values incommensurate with the lattice.

  Competing short- and long-range interactions represent distinguished ingredients for the formation of complex quantum many-body phases. We leverage the van der Waals and dipole-dipole interactions of the Rydberg atoms to obtain the zero-temperature phase diagram for a uniform chain and a dimer model. This demonstrates the versatility of the Rydberg platform in studying physics involving short- and long-ranged interactions simultaneously.

  We investigate the phase diagram of hard-core bosons in a triangular ladder with next-to-nearest-neighbor interaction along each leg. For weak interactions, Abelian bosonization predicts a spin density wave and a fully gapless Luttinger liquid phase. The competition with the zigzag interaction generates a charge density wave, a 'polarized holonic' phase, and a crystalline phase at the filling 2/5.

By placing microwave photons in adjacent qubit sites, we study the propagation of these excitations and observe their bound nature for up to 5 photons.

  We consider a mixture of a Bose-Einstein condensate, with a paired Fermi superfluid, confined in a ring potential.
