Under physiological conditions, ballistic long-range transfer of electronic excitations in molecular aggregates is generally expected to be suppressed by noise and dissipative processes. Hence, quantum phenomena are not considered to be relevant for the design of efficient and controllable energy transfer over significant length and time scales. Contrary to this conventional wisdom, here we show that the robust quantum properties of small configurations of repeating clusters of molecules can be ...

When interacting motile units self-organize into flocks, they realize one of the most robust ordered state found in nature. However, after twenty five years of intense research, the very mechanism controlling the ordering dynamics of both living and artificial flocks has remained unsettled. Here, combining active-colloid experiments, numerical simulations and analytical work, we explain how flocking liquids heal their spontaneous flows initially plagued by collections of topological defects to a...

Fluctuating superconductivity—vestigial Cooper pairing in the resistive state of a material—is usually associated with low dimensionality, strong disorder, or low carrier density. Here, we report single-particle spectroscopic, thermodynamic and magnetic evidence for persistent superconducting fluctuations in the heavily hole-doped cuprate superconductor Bi2Sr2CaCu2O8þδ(Tc¼66 K) despite the high carrier density. With a sign-problem-free quantum Monte Carlo calculation, we show how a partially fla...

We illuminate the many-body effects underlying the structure, formation, and dissolution of cellular adhesion domains in the presence and absence of forces. We consider mixed Glauber-Kawasaki dynamics of a two-dimensional model of nearest-neighbor interacting diffusing adhesion bonds with intrinsic binding-affinity under the action of a shared pulling or pushing force. Highly accurate analytical results are obtained on the pair-correlation level of the Bethe-Guggenheim approximation for the comp...

Active fluids exhibit complex turbulent-like flows at low Reynolds number. Recent work predicted that 2d active nematic turbulence follows universal scaling laws. However, experimentally testing these predictions is conditioned by the coupling to the 3d environment. Here, we measure the spectrum of the kinetic energy, E(q) in an active nematic film in contact with a passive oil layer. At small and intermediate scales, we find the scaling regimes E(q)\sim q^{-4}and E(q)\sim q^{-1} respec...

How fast must an oriented collection of extensile swimmers swim to escape the instability of viscous active suspensions? We show that the answer lies in the dimensionless combination R=\rho v_0^2/2\sigma_a where \rhois the suspension mass density, v_0the swim speed and \sigma_athe active stress. Linear stability analysis shows that for small Rdisturbances grow at a rate linear in their wavenumber q and that the dominant instability mode involves twist. The resulting steady stat...

Quantum phase transitions are central for the understanding of the equilibrium low-temperature properties of quantum matter. Locating them can be challenging both by means of theoretical techniques as well as for experiments. Here, we show that the antithetic strategy of forcing a system strongly out of equilibrium can provide a route to identify signatures of quantum phase transitions. By quenching a quantum chaotic (nonintegrable) spin chain, we find that local observables can exhibit distinct...
