entangled states of photons form the backbone of many quantum technologies. due to the lack of effective photon–photon interactions, the generation of these states is typically probabilistic. in the prevailing but fundamentally limited generation technique, known as postselection, the target photons are measured destructively in the generation process. by contrast, in the alternative approach—heralded

conventional methods to measure the dispersion relations of collective spin excitations involve probing bulk samples with particles such as neutrons, photons, or electrons, which carry a well-defined momentum. open-ended finite-size spin chains, on the contrary, do not have a well-defined momentum due to the lack of translation symmetry, and their spin excitations are measured with an eminently local

chiral magnetic textures are of fundamental interest for studying exotic spin behavior, but also promising for the development of energy-efficient memory and logic devices. recent computational work has suggested that in contrast to well-studied static chiral textures like skyrmions, there exists dynamic fluctuation-driven magnetic chirality even in the absence of long-range magnetic order. here, we

effective thermal regulation is increasingly vital in numerous technological applications. the recent progress on topological diffusion in thermal materials offers promising potential. a distinct feature of diffusive systems is that their anti-hermitian characteristics ensure purely imaginary eigenvalues representing decay rates, where higher decay rates imply better heat dissipation efficiency. although

superconducting chiral domains associated with a time-reversal symmetry-breaking order parameter have garnered significant attention in kagome systems. in this letter, we demonstrate both the intrinsic direct-current and alternating-current josephson effects in the nanoplates of the vanadium-based kagome material csv3⁢sb5, as evidenced by fraunhofer-like patterns and shapiro steps. moreover, both the

liquid foams exhibit menisci whose lengths range from hundreds of microns in microfoams to several centimeters in macroscopic bubble arrangements. these menisci are known to thin under gravity until reaching a steady thickness profile, where hydrostatic and capillary pressures are balanced. however, current drainage models neglect the liquid exchanges between the menisci and the adjacent soap films

rydberg atom radio-frequency sensors are a unique platform for precision electromagnetic field measurement; e.g., they have extraordinary carrier bandwidth spanning mhz to thz and can be self-calibrated. these photonic sensors use lasers to prepare and read out the atomic response to a radio-frequency electromagnetic field. most work on rydberg atom sensors centers on radio-frequency electric field

high temperatures are typically thought to increase disorder. here we examine this idea in quantum field theory in 2 1 dimensions. for this sake we explore a novel class of tractable models, consisting of nearly-mean-field scalars interacting with critical scalars. we identify uv-complete, local, unitary models in this class and show that symmetry breaking ℤ2→∅ occurs at any temperature in some regions

the preparation of nontrivial states is crucial to the study of quantum many-body physics. such states can be prepared with adiabatic quantum algorithms, which are restricted by the minimum spectral gap along the path. in this letter, we propose an efficient method to adiabatically prepare tensor network states (tnss). we maximize the spectral gap leveraging degrees of freedom in the parent hamiltonian

the permutation entropy (pe) is a statistical indicator that allows the quantification of the complexity of a signal. here, we show that it is able to identify and anticipate the threshold bifurcation of a complex laser, where thousands of modes compete for gain at the onset of lasing. in our experimental setup, the cavity round-trip time is several orders of magnitude longer than the temporal resolution

symmetry breaking plays a central role in classifying the phases of quantum many-body systems. recent developments have highlighted a novel symmetry-breaking pattern, in which the strong symmetry of a density matrix spontaneously breaks to the weak symmetry. this strong-to-weak symmetry breaking is typically detected using multireplica correlation functions, such as the rényi-2 correlator. in this

knots emerge in various fields of mathematics and physics today. we show that knots indeed appear as stable solitons in a realistic extension of the standard model of particle physics that provides the qcd axion and right-handed neutrinos. this result suggests that, during the early universe, a “knot dominated era” may have existed, where knots were a dominant component of the universe, and this scenario

we introduce a mixed-state generalization of the multientropy through the canonical purification, which we call “reflected multientropy.” we propose the holographic dual of this measure. for the tripartite case, a field-theoretical calculation is performed using a six-point function of twist operators at large 𝑐 limit. at both zero and finite temperature, the field-theoretical results match the holographic
