Ultracold fermionic atoms in a shaken optical honeycomb lattice map the interband Berry connection via polarization-dependent resonant excitations, revealing transparency lines and Dirac strings between K and K' points.
Continuous-space quantum Monte Carlo shows that in honeycomb optical lattices, density-assisted tunneling suppresses higher Mott lobes, making the standard Bose–Hubbard model inaccurate even for deep lattices.
A two-level emitter coupled to a chiral flat band in a photonic lattice shows Rabi oscillations with a lifted mode whose effective coupling strength and mode volume remain protected against weak hopping disorder.
Breathing mode in Kagome lattices induces odd-frequency spin-singlet dynamical Cooper pairs from conventional s-wave superconductivity.
