Abstract

We show that the anomalous temperature scaling of five distinct transport quantities in the strange metal regime of the cuprate superconductors can be reproduced with only two nontrivial critical exponents. The quantities are (i) the electrical resistivity, (ii) the Hall angle, (iii) the Hall-Lorenz ratio, (iv) the magnetoresistance, and (v) the thermopower. The exponents are the dynamical critical exponent z = 4/3 and an anomalous scaling dimension Phi = -2/3 for the charge density operator.

Summary: The research uncovers the precise quantitative scaling laws among the superconducting transition temperature, the linear-in-T scattering coefficient, and the doping level in electron-doped copper oxide La2-xCexCuO4, suggesting a common mechanism of the strange-metal behavior and unconventional superconductivity in these systems.

Reduced Hall carrier density in the overdoped strange metal regime of cuprate superconductors

Carsten Putzke, Siham Benhabib, Wojciech Tabis, Jake Ayres, Zhaosheng Wang, Liam Malone, Salvatore Licciardello, Jianming Lu, Takeshi Kondo, Tsunehiro Takeuchi, Nigel E. Hussey, John R. Cooper, Antony Carrington

Summary: Study of the high-field Hall coefficient in thallium- and bismuth-based single-layer cuprates reveals a smooth evolution of this quantity from p to 1 + p over a wide doping range. The evolution of n(H) correlates with the emergence of the anomalous linear-in-temperature term in the low-temperature in-plane resistivity, suggesting that quasiparticle decoherence may extend to dopings well beyond the pseudogap regime.

Energy-length scaling of critical phase fluctuations in the cuprate pseudogap phase

Rong Li, Zhen-Su She

Summary: The central conundrum of the cuprate pseudogap and its relationship to symmetry-breaking orders in unconventional superconductors lie in the modeling of simultaneous organizations in multiple degrees of freedom. Recent studies focus on exploring the spatial organization and intertwining mechanism of multiple orders, revealing a universal energy-length scaling. This scaling quantitatively explains the nontrivial magnitude and doping dependence of the pseudogap energy and critical temperature, shedding light on the spatial organization mechanism of intertwined orders and their possible composite energy scaling.

Exchange scaling of ultrafast angular momentum transfer in 4f antiferromagnets

Y. W. Windsor, S-E Lee, D. Zahn, V Borisov, D. Thonig, K. Kliemt, A. Ernst, C. Schuessler-Langeheine, N. Pontius, U. Staub, C. Krellner, D. V. Vyalikh, O. Eriksson, L. Rettig

Summary: This study investigates the magnetization dynamics in 4f antiferromagnets and shows that the rate of direct transfer between opposing moments is directly determined by the magnitude of the Ruderman-Kittel-Kasuya-Yosida (RKKY) coupling energy. The results offer a useful approach for fine tuning the speed of magnetic devices.

Strange physics of dark baryons

Gonzalo Alonso-Alvarez, Gilly Elor, Miguel Escudero, Bartosz Fornal, Benjamin Grinstein, Jorge Martin Camalich

Summary: Dark decays of hadronic states containing strange quarks, known as hyperons, provide a promising framework for understanding the origin of dark matter and the matter-antimatter asymmetry of the universe. By calculating the relevant matrix elements and considering various constraints, we determine the expected rates of hyperon decays at hyperon factories like BESIII and LHCb. We also uncover interesting theoretical connections between hyperon dark decays, the neutron lifetime anomaly, and mesogenesis.

A criterion for strange metallicity in the Lorenz ratio

Evyatar Tulipman, Erez Berg

Summary: The Wiedemann-Franz law, which states the relationship between thermal and electrical conductivities in a metal, is often seen as a characteristic of fermionic Landau quasi-particles. However, this study shows that weakly disordered non-Fermi liquids also follow the Wiedemann-Franz law at low temperatures. The authors suggest using the low-temperature correction to distinguish different types of strange metals.

Is the remnant of GW190425 a strange quark star?

J. Sedaghat, S. M. Zebarjad, G. H. Bordbar, B. Eslam Panah, R. Moradi

Summary: This study explores the impact of different QCD models on the structure of strange quark stars (SQS). By imposing constraints on strange quark matter (SQM) and utilizing analytic and background perturbation theories, the equations of states for SQM are derived. The properties of SQSs in general relativity are then evaluated. The results suggest that the maximum gravitational masses obtained are comparable to the remnant mass of GW190425, implying that GW190425 might be a strange quark star.

Seebeck Coefficient in a Cuprate Superconductor: Particle-Hole Asymmetry in the Strange Metal Phase and Fermi Surface Transformation in the Pseudogap Phase

A. Gourgout, G. Grissonnanche, F. Laliberte, A. Ataei, L. Chen, S. Verret, J-S Zhou, J. Mravlje, A. Georges, N. Doiron-Leyraud, Louis Taillefer

Summary: This study reports on the measurements of the Seebeck effect in La1.6-xNd0.4SrxCuO4, a cuprate superconductor. The Seebeck coefficient is used to investigate the particle-hole asymmetry of the electronic structure across the pseudogap critical doping p* = 0.23. The results show that the Seebeck coefficient is positive and isotropic outside the pseudogap phase, contradicting the expected behavior based on the electronic band structure. Inside the pseudogap phase, the Seebeck coefficient along the c axis becomes negative at low temperature, indicating a novel signature of the pseudogap phase.

Strange attractors for the family of orientation preserving Lozi maps

Przemyslaw Kucharski

Summary: This paper extends the result of Micha & lstrok; Misiurewicz on the existence of strange attractors for orientation reversing Lozi maps to the orientation preserving case. It rigorously determines an open subset of the parameter space for which an attractor always exists and exhibits chaotic properties. The paper also proves that the attractor is maximal in some open parameter region and arises as the closure of the unstable manifold of a fixed point.

Scaling of small-scale wall turbulence

S. L. Tang, R. A. Antonia

Summary: The paper introduces a new hypothesis that suggests near-wall small-scale statistics, when suitably normalized, are independent of flow type as well as Reynolds and Peelet numbers. While the available wall turbulence direct numerical simulations data in a channel flow and a boundary layer provide good support for independence with respect to the Reynolds number, more data are needed to fully validate this hypothesis, particularly for higher-order statistics and other types of wall flows with different surface conditions.

Are Heavy Fermion Strange Metals Planckian?

Mathieu Taupin, Silke Paschen

Summary: Strange metal behavior refers to a linear temperature dependence of the electrical resistivity that is not due to electron-phonon scattering. This phenomenon can be observed in various strongly correlated electron systems, and achieving a unified understanding of this behavior across different materials is a central problem in condensed matter physics.

Schellekens' list and the very strange formula

Jethro van Ekeren, Ching Hung Lam, Sven Moller, Hiroki Shimakura

Summary: In this paper, a fundamentally different and simpler proof of Schellekens' list of 71 Lie algebras is presented. Utilizing the dimension formula and Kac's formula, it is shown how a strongly rational, holomorphic vertex operator algebra with central charge 24 can be constructed from the Leech lattice vertex operator algebra. This method allows for the classification of these vertex operator algebras by studying properties of the Leech lattice, demonstrating the construction for 43 of the 70 non-zero Lie algebras on Schellekens' list, with computationally expensive cases omitted.

Dual scaling and the n-thirds law in grid turbulence

S. L. Tang, R. A. Antonia, L. Djenidi

Summary: This study examines the dual scaling of the turbulent longitudinal velocity structure function and its implications in the context of the Kármán-Howarth equation and experimental grid turbulence data. The results suggest that as the Reynolds number increases, the scaling based on large scale motion extends to smaller scales while the scaling based on the Kolmogorov scales extends to larger scales. This indicates that both scalings should eventually overlap in the inertial range, leading to a power-law relation. The study also highlights the difference in Reynolds number effect between even and odd orders of the structure function.
