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.

Summary: The phenomenon and radical changes observed in material properties during a quantum phase transition have attracted significant attention in condensed matter research in recent decades. Strong electronic correlations give rise to exotic electronic ground states, such as magnetic order, nematicity, and unconventional superconductivity. A detailed understanding of the electronic structure near the Fermi energy is necessary to provide a microscopic model for these phenomena and achieve a complete understanding of the physics of the quantum critical point.

Summary: We report detailed valence fluctuation phenomena in the unique quantum-critical compound 0-YbAlB4 under pressures and at low temperatures. We observed the drastic change in the pressure dependence of the mean Yb valence, and the non-monotonous decrease of the Kondo temperature. The reduced Kondo coherence temperature is found to be responsible for the unconventional quantum critical behaviors in beta-YbAlB4.

Summary: Strange metals exhibit unconventional electrical properties such as linear resistivity, inverse Hall angle, and linear magnetoresistance. Research suggests that these anomalies in cuprates may be related to a quantum critical point inside the superconducting dome, extending beyond the critical doping level. The presence of two charge sectors, one with coherent quasiparticles and the other with scale-invariant 'Planckian' dissipators, indicates a complex behavior in the strange-metal regime.

Summary: In high-temperature cuprate superconductors, the stripe order evolution across optimal doping remains controversial. This study investigates weak charge correlations in La2-xSrxCuO4 and La1.8-xEu0.2SrxCuO4 using resonant inelastic X-ray scattering. The results reveal temperature-dependent long-range stripe order only below optimal doping, while temperature-independent short-range correlations exist at higher doping, suggesting an unresolved electron-phonon coupling origin.

These anomalies only appear in the antiferromagnetic state, and while they are similar in shape, the changes in sound velocity have opposite signs.

Summary: CeOs4Sb12, a member of the skutterudite family, exhibits an unusual semimetallic low-temperature L-phase. The influence of pressure on the different H-T phase boundaries in CeOs4Sb12 was investigated through electrical transport and megahertz conductivity measurements. The results showed changes in properties such as the decrease in Fermi surface size and marginal suppression of the low-temperature phase under high pressure.

Summary: Defects and structural inhomogeneities in crystals can significantly impact the electronic properties of nematic materials, resulting in the emergence of an incommensurate electronic smectic phase. This effect may explain observations of modulated nematic phases in iron-based superconductors and previous puzzling experiments showing signs of nematic order before bulk structural distortion.

Summary: In this study, a unique method to adjust optical bistability and optical multistability in a ring cavity inclusive of a three-level quantum system is proposed based on quantum mean-field theory. The interactions between the quantum system, weak probe light, incoherent pumping field, and coupling light carrying an optical vortex were found to exhibit characteristics not previously reported in comparable studies.

Summary: The entanglement dynamics in hybrid Z(2)-symmetric quantum automaton circuits subject to local composite measurements were studied, revealing an entanglement phase transition from a volume-law phase to a critical phase by varying the measurement rate p. The critical point belongs to parity-conserving universality class, and the critical phase with p > p(c) is related to the diffusion-annihilation process and protected by Z(2)-symmetric measurement. The interpretation of entanglement entropy and identification of the coefficient in front of the critical logarithmic entanglement scaling were provided.

Summary: To capture the universal low-energy physics of metals within effective field theories, we develop a field-theoretic functional renormalization group formalism for full low-energy effective field theories of non-Fermi liquids. The formalism is applied to the non-Fermi liquid that arises at the antiferromagnetic quantum critical point in two space dimensions. In theories deformed with non-zero nesting angles, coupling functions acquire universal momentum profiles controlled by the bare nesting angles at low energies before flowing to superconducting states in the low-energy limit.

Summary: Considerable recent progress has been made in identifying candidate materials for the transverse-field Ising chain (TFIC), a paradigmatic model for quantum criticality. In this study, we investigate the local spin dynamical structure factor of different spin components in the quantum disordered region of the TFIC. Our findings reveal surprising temperature dependencies in the low-frequency local dynamics of spins in the Ising and transverse-field directions.

Summary: In this study, the thermoelectric response in heavily overdoped, non-superconducting La1.67Sr0.33CuO4 was investigated. Despite the electron-like curvature of the Fermi surface, the positive Seebeck coefficient at low temperatures was observed, which is attributed to the non-trivial energy dependence of the scattering time. It is argued that this feature implies a strong electron-hole asymmetry, hindering the formation of Cooper pairs in the superconducting ground state at lower doping levels.

Summary: Research shows that the normal superconducting state of overdoped cuprates consists of two distinct charge sectors - one governed by coherent quasiparticle excitations and the other characterized by non-quasiparticle dissipation. The superfluid density decreases with increased hole doping, reaching zero at the superconducting dome edge, while the Hall number transitions from p to 1+p. The growth in superfluid density may be compensated by the loss of carriers in the coherent sector as hole doping decreases.

Summary: Once doped away from their parent Mott insulating state, the hole-doped cuprates enter into many varied and exotic phases. The onset temperature of each phase is then plotted versus p-the number of doped holes per copper atom-to form a representative phase diagram. Apart from differences in the absolute temperature scales among the various families, the resultant phase diagrams are strikingly similar. In particular, the p values corresponding to optimal doping and to the end of the pseudogap phase are essentially the same for all cuprate families except for the single-layer Bi-based cuprate Bi2+z-yPbySr2-x-zLaxCuO6+delta (Bi2201). This anomaly arises partly due to the complex stoichiometry of this material and also to the different p values inferred from disparate measurements performed on samples with comparable superconducting transition temperatures T-c. Here, by combining measurements of in-plane resistivity in zero and high magnetic fields with angle-resolved photoemission spectroscopy studies, we argue that the phase diagram of Bi2201 may actually be similar to that realized in other families, supporting the notion of universality of p(opt) and p* in all hole-doped cuprates.

Summary: This study investigates the resistivity behavior in undoped nickelate materials and examines the impact of disorder and doping on its temperature dependence. The results reveal that the level of doping has little correlation with the magnitude and onset temperature of the resistivity upturn, while the different rare-earth families play a crucial role in the evolution of the insulating behavior.

Summary: Strange metals are a class of materials that defy the traditional temperature dependence of electrical resistivity at both low and high temperatures. By studying the transport and spectroscopic data of these materials, we aim to identify a unifying physical principle, with special focus on quantum criticality, Planckian dissipation, Mottness, and the possible requirement of a new gauge principle to explain the nonlocal transport observed in these materials.

Summary: Strange metals exhibit a linear increase in resistivity with magnetic field. The presence of strong anisotropic scattering can generate magnetoresistance, but it saturates at high magnetic field strengths. A bounded sector on the Fermi surface is required for the realization of quadratic-to-linear magnetoresistance.

Summary: The systematic magnetotransport study of superconducting infinite-layer nickelate thin films Nd1-xSrxNiO2 indicates a crossover in normal state resistivity behavior, pointing to a possibly anomalous insulating state driven by strong correlations. Additionally, no evidence of non-Fermi-liquid behavior was found in the metallic state near a putative quantum critical point.
