  text: Most natural and engineered information-processing systems transmit information
    via signals that vary in time. Computing the information transmission rate or
    the information encoded in the temporal characteristics of these signals requires
    the mutual information between the input and output signals as a function of time,
    i.e., between the input and output trajectories. Yet, this is notoriously difficult
    because of the high-dimensional nature of the trajectory space, and all existing
    techniques require approximations. We present an exact Monte Carlo technique called
    path weight sampling (PWS) that, for the first time, makes it possible to compute
    the mutual information between input and output trajectories for any stochastic
    system that is described by a master equation. The principal idea is to use the
    master equation to evaluate the exact conditional probability of an individual
    output trajectory for a given input trajectory and average this via Monte Carlo
    sampling in trajectory space to obtain the mutual information. We present three
    variants of PWS, which all generate the trajectories using the standard stochastic
    simulation algorithm. While direct PWS is a brute-force method, Rosenbluth-Rosenbluth
    PWS exploits the analogy between signal trajectory sampling and polymer sampling,
    and thermodynamic integration PWS is based on a reversible work calculation in
    trajectory space. PWS also makes it possible to compute the mutual information
    between input and output trajectories for systems with hidden internal states
    as well as systems with feedback from output to input. Applying PWS to the bacterial
    chemotaxis system, consisting of 182 coupled chemical reactions, demonstrates
    not only that the scheme is highly efficient but also that the number of receptor
    clusters is much smaller than hitherto believed, while their size is much larger.

  text: Universal nonequilibrium properties of isolated quantum systems are typically
    probed by studying transport of conserved quantities, such as charge or spin,
    while transport of energy has received considerably less attention. Here, we study
    infinite-temperature energy transport in the kinetically constrained PXP model
    describing Rydberg atom quantum simulators. Our state-of-the-art numerical simulations,
    including exact diagonalization and time-evolving block decimation methods, reveal
    the existence of two distinct transport regimes. At moderate times, the energy-energy
    correlation function displays periodic oscillations due to families of eigenstates
    forming different su(2) representations hidden within the spectrum. These families
    of eigenstates generalize the quantum many-body scarred states found in previous
    works and leave an imprint on the infinite-temperature energy transport. At later
    times, we observe a long-lived superdiffusive transport regime that we attribute
    to the proximity of a nearby integrable point. While generic strong deformations
    of the PXP model indeed restore diffusive transport, adding a strong chemical
    potential intriguingly gives rise to a well-converged superdiffusive exponent
    z≈3/2. Our results suggest constrained models to be potential hosts of novel transport
    regimes and call for developing an analytic understanding of their energy transport.

  text: "Ultrafast lasers are an increasingly important tool to control and stabilize
    emergent phases in quantum materials. Among a variety of possible excitation protocols,
    a particularly intriguing route is the direct light engineering of microscopic
    electronic parameters, such as the electron hopping and the local Coulomb repulsion
    (Hubbard \r\nU). In this work, we use time-resolved x-ray absorption spectroscopy
    to demonstrate the light-induced renormalization of the Hubbard U in a cuprate
    superconductor, La1.905Ba0.095CuO4. We show that intense femtosecond laser pulses
    induce a substantial redshift of the upper Hubbard band while leaving the Zhang-Rice
    singlet energy unaffected. By comparing the experimental data to time-dependent
    spectra of single- and three-band Hubbard models, we assign this effect to an
    approximately 140-meV reduction of the on-site Coulomb repulsion on the copper
    sites. Our demonstration of a dynamical Hubbard U renormalization in a copper
    oxide paves the way to a novel strategy for the manipulation of superconductivity
    and magnetism as well as to the realization of other long-range-ordered phases
    in light-driven quantum materials."

  text: Dipolar coupling plays a fundamental role in the interaction between electrically
    or magnetically polarized species such as magnetic atoms and dipolar molecules
    in a gas or dipolar excitons in the solid state. Unlike Coulomb or contactlike
    interactions found in many atomic, molecular, and condensed-matter systems, this
    interaction is long-ranged and highly anisotropic, as it changes from repulsive
    to attractive depending on the relative positions and orientation of the dipoles.
    Because of this unique property, many exotic, symmetry-breaking collective states
    have been recently predicted for cold dipolar gases, but only a few have been
    experimentally detected and only in dilute atomic dipolar Bose-Einstein condensates.
    Here, we report on the first observation of attractive dipolar coupling between
    excitonic dipoles using a new design of stacked semiconductor bilayers. We show
    that the presence of a dipolar exciton fluid in one bilayer modifies the spatial
    distribution and increases the binding energy of excitonic dipoles in a vertically
    remote layer. The binding energy changes are explained using a many-body polaron
    model describing the deformation of the exciton cloud due to its interaction with
    a remote dipolar exciton. The surprising nonmonotonic dependence on the cloud
    density indicates the important role of dipolar correlations, which is unique
    to dense, strongly interacting dipolar solid-state systems. Our concept provides
    a route for the realization of dipolar lattices with strong anisotropic interactions
    in semiconductor systems, which open the way for the observation of theoretically
    predicted new and exotic collective phases, as well as for engineering and sensing
    their collective excitations.

  text: "Molecular chirality plays an essential role in most biochemical processes.
    The observation and quantification of chirality-sensitive signals, however, remains
    extremely challenging, especially on ultrafast timescales and in dilute media.
    Here, we describe the experimental realization of an all-optical and ultrafast
    scheme for detecting chiral dynamics in molecules. This technique is based on
    high-harmonic generation by a combination of two-color counterrotating femtosecond
    laser pulses with polarization states tunable from linear to circular. We demonstrate
    two different implementations of chiral-sensitive high-harmonic spectroscopy on
    an ensemble of randomly oriented methyloxirane molecules in the gas phase. Using
    two elliptically polarized fields, we observe that the ellipticities maximizing
    the harmonic signal reach up to \r\n4.4\r\n±\r\n0.2\r\n%\r\n (at 17.6 eV). Using
    two circularly polarized fields, we observe circular dichroisms ranging up to
    \r\n13\r\n±\r\n6\r\n%\r\n (28.3–33.1 eV). Our theoretical analysis confirms that
    the observed chiral response originates from subfemtosecond electron dynamics
    driven by the magnetic component of the driving laser field. This assignment is
    supported by the experimental observation of a strong intensity dependence of
    the chiral effects and its agreement with theory. We moreover report and explain
    a pronounced variation of the signal strength and dichroism with the driving-field
    ellipticities and harmonic orders. Finally, we demonstrate the sensitivity of
    the experimental observables to the shape of the electron hole. This technique
    for chiral discrimination will yield femtosecond temporal resolution when integrated
    in a pump-probe scheme and subfemtosecond resolution on chiral charge migration
    in a self-probing scheme."
