Out-of-time-ordered correlators of the Hubbard model: SYK strange metal in the spin freezing crossover region

description: The Sachdev-Ye-Kitaev (SYK) model describes a strange metal that shows peculiar non-Fermi liquid properties without quasiparticles. It exhibits a maximally chaotic behavior characterized by out-of-time-ordered correlators (OTOCs), and is expected to be a holographic dual to black holes. Recently, a striking similarity between the SYK model and the Hund-coupling induced spin-freezing crossover in multi-orbital Hubbard models has been pointed out. To further explore this connection, we study OTOCs for fermionic Hubbard models, which are prototypical models for strongly correlated electrons in solids. We introduce an imaginary-time four-point correlation function with an appropriate time ordering, which by means of the spectral representation and the out-of-time-order fluctuation-dissipation theorem can be analytically continued to real-time OTOCs. Based on this approach, we numerically evaluate real-time OTOCs for Hubbard models in the thermodynamic limit, using the dynamical mean-field theory in combination with a numerically exact continuous-time Monte Carlo impurity solver. The results for the single-orbital model show that a certain spin-related OTOC captures local moment formation in the vicinity of the metal-insulator transition, while the self-energy does not show SYK-like non-Fermi liquid behavior. On the other hand, for the two- and three-orbital models with nonzero Hund coupling we find that the OTOC exhibits a rapid damping at short times and an approximate power-law decay at longer times in the spin-freezing crossover regime characterized by fluctuating local moments and a non-Fermi liquid self-energy $Σ(ω) \sim \sqrtω$. These results are in a good agreement with the behavior of the SYK model, providing firm evidence for the close relation between the spin-freezing crossover physics of multi-orbital Hubbard models and the SYK strange metal.

description: The discovery of collectivity in proton-proton collisions, is one of the most puzzling outcomes from the two first runs at LHC, as it points to the possibility of creation of a Quark-Gluon Plasma, earlier believed to only be created in heavy ion collisions. One key observation from heavy ion collisions is still not observed in proton-proton, namely jet-quenching. In this letter it is shown how a model capable of describing soft collective features of proton-proton collisions, also predicts modifications to jet fragmentation properties. With this starting point, several new observables suited for the present and future hunt for jet quenching in small collision systems are proposed.

description: In this paper, we present a deep learning architecture which addresses the problem of 3D semantic segmentation of unstructured point clouds. Compared to previous work, we introduce grouping techniques which define point neighborhoods in the initial world space and the learned feature space. Neighborhoods are important as they allow to compute local or global point features depending on the spatial extend of the neighborhood. Additionally, we incorporate dedicated loss functions to further structure the learned point feature space: the pairwise distance loss and the centroid loss. We show how to apply these mechanisms to the task of 3D semantic segmentation of point clouds and report state-of-the-art performance on indoor and outdoor datasets.

description: We use first principles density functional theory calculations to investigate the effect of biaxial strain in the low-temperature structural and ferroelectric properties of [111]-oriented SrTiO$_3$. We find that [111] biaxial strain, achievable by coherent epitaxial growth along the [111] direction, induces structural distortions in SrTiO$_3$ that are not present in either bulk or [001]-oriented SrTiO$_3$. Under [111] biaxial strain, SrTiO$_3$ displays ferroelectricity at tensile strain, and paraelectricity at compressive strain. We compute the phonon spectrum and macroscopic polarization of SrTiO$_3$ as a function of [111] biaxial strain, and relate our results to the predictions of the free energy phenomenological model of Pertsev, Tagantsev and Setter [Phys. Rev. B 61, 825 (2000); Phys. Rev. B 65, 219901 (2002)].

description: Over the past two decades, mindfulness has received considerable attention in the organizational sciences, and researchers have even begun examining how a leader’s mindfulness may manifest interpersonally to benefit those around them. However, these studies have conceptualized and measured mindfulness from a unidimensional perspective, leaving a potential gap in the literature regarding which dimensions of mindfulness are more or less important for interindividual outcomes. The two studies presented in this paper sought to build on previous findings by evaluating mindfulness from a multidimensional lens. The first study involved a cross-sectional survey (n=306) designed to examine the factor structure of the Five Facet Mindfulness Questionnaire (FFMQ) and evaluate the relationship between supervisor mindfulness and direct report performance. The factor structure of the FFMQ was confirmed; however, results suggested that neither aggregate supervisor mindfulness nor the individual dimensions significantly predicted performance of their direct reports. In the second study, survey data was collected from a sample of supervisors (n=92). The factor structure identified in the first study was used to predict direct report performance as well as organizational citizenship behavior (OCB). Findings were consistent with the first study in that overall supervisor mindfulness did not predict either outcome; however, one dimension of the FFMQ was found as a significant predictor of both overall performance and OCB. Potential implications and limitations are discussed.

description: We show that the novel features observed in Raman experiments on optimally doped and underdoped Bi-2212 compounds in $B_{1g}$ geometry can be explained by a strong fermionic self-energy due to the interaction with spin fluctuations. We compute the Raman intensity $R(ω)$ both above and below $T_c$, and show that in both cases $R(ω)$ progressively deviates, with decreasing doping, from that in a Fermi-gas due to increasing contribution from the fermionic self-energy. We also show that the final state interaction increases with decreasing doping and gradually transforms the $2Δ$ peak in the superconducting state into a pseudo resonance mode below $2Δ$. We argue that these results agree well with the experimental data for Bi-2212.

Utility of Galilean Symmetry in Light-Front Perturbation Theory: A Nontrivial Example in QCD

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Investigations have revealed a very complex structure for the coefficient functions accompanying the divergences for individual time ($x^+$) ordered diagrams in light-front perturbation theory. No guidelines seem to be available to look for possible mistakes in the structure of these coefficient functions emerging at the end of a long and tedious calculation, in contrast to covariant field theory. Since, in light-front field theory, transverse boost generator is a kinematical operator which acts just as the two-dimensional Galilean boost generator in non-relativistic dynamics, it may provide some constraint on the resulting structures. In this work we investigate the utility of Galilean symmetry beyond tree level in the context of coupling constant renormalization in light-front QCD using the two-component formalism. We show that for each $x^+$ ordered diagram separately, underlying transverse boost symmetry fixes relative signs of terms in the coefficient functions accompanying the diverging logarithms. We also summarize the results leading to coupling constant renormalization for the most general kinematics.

The resultant continuous concentration profile can be digitized into an easily realizable rectangular-wells structure.

description: Quantum information and communication processing within quantum networks usually employs identical particles. Despite this, the physical role of quantum statistical nature of particles in large-scale networks remains elusive. Here, we show that just the indistinguishability of fermions makes it possible a new mechanism of entanglement transfer in many-node quantum networks. This process activates remote entanglement among distant sites, which do not share a common past, by only locally counting identical particles and classical communication. These results constitute the key achievement of the present technique and open the way to a more stable multistage transfer of nonlocal quantum correlations based on fermions.

description: Similar to their low-mass counterparts, massive stars likely form via the collapse of pre-stellar molecular cores. Recent observations suggest that most massive cores are subvirial (i.e., not supported by turbulence) and therefore are likely unstable to gravitational collapse. Here we perform radiation hydrodynamic simulations to follow the collapse of turbulent massive pre-stellar cores with subvirial and virialized initial conditions to explore how their dynamic state affects the formation of massive stars and core fragmentation into companion stars. We find that subvirial cores undergo rapid monolithic collapse resulting in higher accretion rates at early times as compared to the collapse of virialized cores that have the same physical properties. In contrast, we find that virialized cores undergo a slower, gradual collapse and significant turbulent fragmentation at early times resulting in numerous companion stars. In the absence of strong magnetic fields and protostellar outflows we find that the faster growth rate of massive stars that are born out of subvirial cores leads to an increase in the radiative heating of the core thereby further suppressing fragmentation at early times when turbulent fragmentation occurs for virialized cores. Regardless of initial condition, we find that the massive accretion disks that form around massive stars dominant the accretion flow onto the star at late times and eventually become gravitationally unstable and fragment to form companion stars at late times.

description: We predict a non-monotonous temperature dependence of the persistent currents in a ballistic ring coupled strongly to a stub in the grand canonical as well as in the canonical case. We also show that such a non-monotonous temperature dependence can naturally lead to a $ϕ_0/2$ periodicity of the persistent currents, where $ϕ_0$=h/e. There is a crossover temperature $T^*$, below which persistent currents increase in amplitude with temperature while they decrease above this temperature. This is in contrast to persistent currents in rings being monotonously affected by temperature. $T^*$ is parameter-dependent but of the order of $Δ_u/π^2k_B$, where $Δ_u$ is the level spacing of the isolated ring. For the grand-canonical case $T^*$ is half of that for the canonical case.

description: As a form of pollution source control and a low-impact development measure, bioretention is a convenient, economical, and effective method for the removal of heavy metals from stormwater runoff, which can adapt to the randomness and uncontrollability of non-point source pollution. However, few studies have assessed the performance of bioretention in the simultaneous removal of multiple heavy metals and the impact of heavy metal migration on the bioretention life cycle. In this study, the removal rates of various heavy metals: copper (Cu), zinc (Zn), lead (Pb), and cadmium (Cd), were enhanced using a biochar modified bioretention cell, as compared to the traditional sandy soil bioretention process. Following treatment with the biochar modified bioretention cell, the average concentrations of Cu, Zn, Pb, and Cd were 55%, 61%, 19.66%, and 36.43% lower than the traditional sandy soil bioretention effluent, respectively. These results show that biochar significantly improves the removal of heavy metals by the bioretention process, especially Cu and Zn. This study also evaluated the effect of biochar on the inhibition of heavy metal migration in the filler material, by sampling and analysing the filler and retained water at different filler depths, then repeating the filler leaching experiment after simulated rainfall. The content of heavy metals at a filler depth of 45 cm in the traditional sandy soil bioretention system, was significantly higher than in the biochar modified bioretention system, showing that biochar plays an important role in the inhibition of heavy metal migration.
A geometric multigrid library for quadtree/octree AMR grids coupled to MPI-AMRVAC

description: We present an efficient MPI-parallel geometric multigrid library for quadtree (2D) or octree (3D) grids with adaptive refinement. Cartesian 2D/3D and cylindrical 2D geometries are supported, with second-order discretizations for the elliptic operators. Periodic, Dirichlet, and Neumann boundary conditions can be handled, as well as free-space boundary conditions for 3D Poisson problems, for which we use an FFT-based solver on the coarse grid. Scaling results up to 1792 cores are presented. The library can be used to extend adaptive mesh refinement frameworks with an elliptic solver, which we demonstrate by coupling it to MPI-AMRVAC. Several test cases are presented in which the multigrid routines are used to control the divergence of the magnetic field in magnetohydrodynamic simulations.

Σκοπός της παρούσας διπλωματικής εργασίας είναι η μελέτη της προσροφητικής ικανότητας τροποποιημένων βιοεξανθρακωμάτων από κελύφη αμυγδάλου ως προς τη ρόφηση αμμωνίου από υδατικά διαλύματα. Τα κελύφη αμυγδάλου πυρολύθηκαν στους 700oC και στη συνέχεια ενεργοποιήθηκαν με ατμό. Τα τροποποιημένα βιοεξανθρακώματα παρασκευάστηκαν με ανάμειξη δολομίτη σε αναλογία 1:1 και εμποτισμό με υδροξείδιο του καλίου (ΚΟΗ). Κατά τη μελέτη της κινητικής της αντίδρασης, ο χρόνος ισορροπίας βρέθηκε 1h, με ποσοστό προσρόφησης αμμωνίου 47.2%. Για τον προσδιορισμό της προσροφητικής ικανότητας των βιοεξανθρακωμάτων, παρασκευάστηκαν υδατικά διαλύματα αμμωνίου με συγκεντρώσεις 10, 50, 100, 150, 200, 250 και 300 mg/L και στη συνέχεια αναμείχθηκαν με τον προσροφητή σε συγκέντρωση 4g/L. Οι ισόθερμες Langmuir και Freundlich εφαρμόστηκαν για την προσομοίωση των πειραματικών δεδομένων. Το μοντέλο Freundlich προσομοίωσε τα αποτελέσματα με μεγάλη ακρίβεια, υποδηλώνοντας πολυστρωματική ρόφηση. Με βάση τα πειραματικά αποτελέσματα, το μη τροποποιημένο βιοεξανθράκωμα παρουσίασε σχετικά χαμηλή προσροφητική ικανότητα, ενώ τα τροποποιημένα βιοεξανθρακώματα με δολομίτη και ΚΟΗ παρουσίασαν βελτιωμένη ικανότητα προσρόφησης 40.3 mg/g και 36.3 mg/g, αντίστοιχα.

 Type:—[RUSSIA] the Altai, Ust-Kan District, the Yabagan Pass, 18 Aug 1984, A. Krasnikov & D. Shaulo (NS, holotype, currently missing).
 The protologue of T. krasnikovii shows a relatively robust plant (to 20–25 cm tall!), with leaves to 15 cm long, glabrous, runcinate; outer phyllaries have a ± narrow shape (oblong-lanceolate), with apex corniculate (horns to 1 mm long!), involucre pale green, and achenes red-brown, medium long, with a relatively long (1–1.2 mm), cylindrical cone.
 Both the above names share a serious shortcoming: their type specimens are missing, perhaps even not extant, and cannot be located in the NS herbarium (N. Kovtonyuk, in litt.). The descriptions in the protologues are rather incomplete (posture, border and size of outer phyllaries, stigma colour and pollen presence are missing), and the illustration of T. rupestre does not help in this respect, either. The type localities of both names were visited during the 1988 expedition; we failed to find any material matching the protologue data there. We therefore do not interpret these two names at present, pending new gatherings at the type sites and/or the re-appearance of the type specimens.

description: An approach is proposed to determine parameters of homogeneous and inhomogeneous broadening for reflection lines of quasi-two-dimensional excitons in semiconductor quantum well structures. A phenomenological model is developed taking into account fluctuations of the exciton energy which are expected to cause inhomogeneous broadening of exciton reflectivity lines. This concept is applied to magneto-optical studies of CdTe/(Cd,Mg)Te single quantum well heterostructures containing a two-dimensional electron gas. By the analysis of excitonic reflection spectra in magnetic fields the parameters of homogeneous and inhomogeneous broadening of the exciton as well as their temperature dependencies were obtained.

Comment on "Transverse Force on a Quantized Vortex in a Superfluid"
Creators: name: Volovik, G. E.
Publisher: name: arXiv
Year: 1996
Subjects: subject: Condensed Matter (cond-mat)
subject: FOS: Physical sciences

description: The result of Thouless, Ao and Niu (TAN), that the mutual friction parameter $d_\perp =0$, contradicts to the experiments made in rotating 3He-B by Manchester group. The Manchester group observed that $d_\perp <0$ at low temperature and approaches 1 at high temperature. The reason of the contradiction is that TAN did not take into account the Iordanskii force on the vortex and the spectral flow force, which comes from the anomaly related to the low-energy bound states of fermions in cores of quantized vortices. The Iordanskii force is responsible for the negative $d_\perp <0$ at low temperature, while due to the spectral flow $d_\perp$ approaches 1 at high temperature. Relation of the spectral flow anomaly with the paradoxes of the linear and angular momenta in gapless superfluids is discussed.

Search for a heavy magnetic monopole at the Fermilab Tevatron and CERN LHC

description: If a heavy Dirac monopole exists, the light to light scattering below the monopole production threshold is enhanced due to the strong coupling of monopoles to photons. This effect could be observable in the collision of virtual photons at proton colliders. At the Tevatron it will be seen as pair production of photons with energies 200--400 GeV and roughly compensated transverse momenta 100--400 GeV/c. This effect could be seen at monopole masses about 1--2.5 TeV at the upgraded Tevatron and 7.4--19 TeV at LHC depending on monopole spin.

Instantaneous Normal Mode Analysis of Supercooled Water

description: We use the instantaneous normal mode approach to provide a description of the local curvature of the potential energy surface of a model for water. We focus on the region of the phase diagram in which the dynamics may be described by the mode-coupling theory. We find, surprisingly, that the diffusion constant depends mainly on the fraction of directions in configuration space connecting different local minima, supporting the conjecture that the dynamics are controlled by the geometric properties of configuration space. Furthermore, we find an unexpected relation between the number of basins accessed in equilibrium and the connectivity between them.

Enhanced propagation of motile bacteria on surfaces due to forward scattering

description: How motile bacteria move near a surface is a problem of fundamental biophysical interest and is key to the emergence of several phenomena of biological, ecological and medical relevance, including biofilm formation. Solid boundaries can strongly influence a cell's propulsion mechanism, thus leading many flagellated bacteria to describe long circular trajectories stably entrapped by the surface. Experimental studies on near-surface bacterial motility have, however, neglected the fact that real environments have typical microstructures varying on the scale of the cells' motion. Here, we show that micro-obstacles influence the propagation of peritrichously flagellated bacteria on a flat surface in a non-monotonic way. Instead of hindering it, an optimal, relatively low obstacle density can significantly enhance cells' propagation on surfaces due to individual forward-scattering events. This finding provides insight on the emerging dynamics of chiral active matter in complex environments and inspires possible routes to control microbial ecology in natural habitats.

description: This report moves beyond the question of whether or not to engage in dialogue with an armed group and explores the spaces in which armed groups operate and their relationships with the people who live there. While local populations are not just passive actors in conflict zones, simply coerced by armed actors, it is equally true that armed groups do not merely exploit or abuse communities in areas in which they operate. Three in-depth case studies from Colombia, northern Uganda and Syria, as well as a shorter analysis from Northern Ireland, illustrate how communities have tried to influence the behavior of armed groups away from violence, and the factors that have affected their interactions – most of which took place in advance of more formal negotiations and often in situations of intense violence and embedded conflict. These local “spaces in between” fighting and talking shed light on the possibilities for more upstream engagement with armed groups and the variety of peace efforts involved in shaping their decisions. The case studies illustrate that reaching out to armed groups does not have to legitimate their tactics or even ambitions. They also show how active community engagement with armed groups can make an important contribution to local human security and peacebuilding. The experiences documented confirm that local peace actors face huge security risks – unprotected by diplomatic immunity or the security of the state. Armed groups often have a blatant disregard for civilian security, or worse, purposefully target populations. Local populations also face security threats from the state, which often views communities close to armed groups as complicit. Active contact by a community with an armed group risks exacerbating perceptions of association.
A model for the atomic-scale structure of a dense, nonequilibrium fluid: the homogeneous cooling state of granular fluids

description: It is shown that the equilibrium Generalized Mean Spherical Model of fluid structure may be extended to nonequilibrium states with equation of state information used in equilibrium replaced by an exact condition on the two-body distribution function. The model is applied to the homogeneous cooling state of granular fluids and upon comparison to molecular dynamics simulations is found to provide an accurate picture of the pair distribution function.

Black-Hole-Enhanced Quantum Entanglement and Teleportation: A Semiclassical and Control-Theoretic Approach
Creators: name: Hilmir F. Halldórsson

Publisher: name: Zenodo
Year: 2025

description: This research explores the intersection of quantum mechanics, general relativity, and quantum information theory, offering new insights into the role of back-reaction in quantum entanglement near black hole horizons. By introducing a novel framework combining fractal-enhanced Bell correlations, semiclassical back-reaction, and real-time feedback control, we propose a protocol for maintaining entanglement stability and enabling quantum teleportation across black hole event horizons.

We develop an analytical model to compute the back-reaction multiplier Gback(r)G_{\rm back}(r)Gback(r) for conformally coupled scalar fields in Schwarzschild spacetime. By applying this model to the standard CHSH parameter, we quantify the enhanced correlations that arise due to the curvature near black hole horizons. Through comparison with numerical entanglement-harvesting results from Unruh–DeWitt detectors, we validate the framework’s accuracy and demonstrate its relevance to the information paradox and Page curves.

Furthermore, we incorporate real-time feedback control to stabilize the quantum channel, demonstrating how the feedback term can maintain Bell violations above the classical limit S=2S = 2S=2 for extended periods. This work lays the foundation for exploring quantum information transfer through black hole analogs and suggests potential experimental tests in laboratory systems such as optical fibers, Bose–Einstein condensates, and superconducting circuits.
