Summary: Recent measurements of resistivity in magic-angle twisted bilayer graphene near the superconducting transition temperature exhibit twofold anisotropy when changing the direction of an in-plane magnetic field. This was interpreted as evidence for exotic nematic superconductivity. However, experimental findings suggest that in-plane magnetic field can hybridize chiral superconducting order parameters to induce nematicity in the transport response.

Summary: The study used scanning Hall probe microscopy to investigate vortex patterns in commercial GdBaCuO tapes, revealing highly disordered vortices pinned by nanoscale Gd2O3 inclusions. The broad vortex profiles, with little temperature dependence, suggest disruption of supercurrents due to high density of nanoscale pinning sites. Measurements also indicate rapid relaxation of critical state profiles by flux creep, providing important insights into the enhancement of critical current in these tapes.

Summary: We performed spectroscopy of a quantum dot Josephson junction using a hybrid superconductor-semiconductor transmon device. The spin-orbit coupling in the device allowed us to observe two flux-sensitive branches in the transmon spectrum. A finite magnetic field caused a shift in the energy of the branches, favoring one spin state and resulting in the anomalous Josephson effect. We successfully demonstrated the excitation of the direct spin-flip transition using all-electrical control, which could enable the future implementation of charging energy protected Andreev spin qubits.

Summary: This study investigates the pairing mechanism in Bi2212 cuprate using angle resolved photoemission spectroscopy data and the Bethe-Salpeter equation. The authors suggest that a spin-mediated pairing interaction plays a dominant role in the formation of Cooper pairs and can account for the high superconducting temperature.

This system achieves high coupling rates and ultrahigh cooperativities, allowing for efficient quantum state transfer.

Summary: This study establishes a quantitative phase diagram of the vortex ratchet motion in the superconducting material (SnS)1.17NbS2 using nonreciprocal magnetotransport. The research shows that the ratchet motion of superconducting vortices is responsive to current excitation, magnetic field, and thermal perturbation. A nonreciprocal coefficient is derived to quantify the magnitude of the vortex ratchet motion.

Summary: The study shows that event-shape engineering based on the mean transverse momentum of charged hadrons provides an optimal handle on the strength of the magnetic field in central heavy-ion collisions. Quantitative evaluations reveal a correlation between the event-by-event magnetic field and [p(t)]. The new method offers advantages for the experimental search of the chiral magnetic effect.

Summary: The study experimentally investigated the vortex pinning in two bilayer FeSCs, CaKFe4As4(Fe1144) and KCa2Fe4As4F2(Fe12442), revealing a higher flux pinning energy in Fe1144. By combining data from other FeSCs, an anti-correlation was found between the pinning energy and superconducting anisotropy in these materials, indicating the importance of interlayer interaction when considering vortex pinning in FeSCs.

Summary: Competing orders in a two-dimensional limit play a crucial role in understanding unconventional superconductivity. By fabricating an ultrathin 2H-NbSe2 device and conducting transport measurements, superconducting and CDW transitions were observed, with the superconducting gap estimated using BTK theory. Features resembling a precursor superconductivity similar to cuprate superconductors were also identified in the normal state.

Additionally, the samples follow the Tinkham model for angle dependent upper critical field, showing significant dimensionality effects different from cuprate superconductors.

Summary: This study systematically investigated the high-pressure behavior of TlInTe2 using Raman spectroscopy, synchrotron X-ray diffraction, and transport measurements. The results showed multiple phase transitions under high pressure, including a pressure-induced semiconductor-to-semimetal transition and a superconducting transition. Additionally, an unusual giant phonon mode softening phenomenon was observed, attributed to the interaction of optical phonons with the conduction electrons.

Summary: We report a new material, CrSb2, which exhibits rewritable pressure and temperature dual-controlled n-p conduction type switching. The material undergoes a pressure-driven n-p conductivity transition at room temperature, accompanied by a structural transition and a semiconductor-to-metal transition. This transition is irreversible but can be reversed through annealing. The underlying mechanism is revealed through characterization and analysis of the microstructure, lattice distortion, and residual stress induced by compression.

Summary: We present magneto-transport measurements of WTe2 thin film devices with current applied along and perpendicular to the in-plane directions. The devices consist of a van der Waals thin film of WTe2 sandwiched between top and bottom Au electrodes. Our results reveal unsaturated magnetoresistance and Shubnikov-de Haas oscillations in the in-plane direction, as well as saturated longitudinal magnetoresistance and quantum oscillations in the out-of-plane direction in a WTe2 thin film. This study provides insights into the unsaturated magnetoresistance of WTe2 and offers potential for non-planar engineering in spintronics.

Summary: This study reports the existence of nearly massless Dirac fermions in BaMnSb2 and investigates its properties under different pressures. It is found that the frequency of the SdH oscillation remains unchanged under different pressures, indicating a relatively stable Fermi surface. Interestingly, a sudden change in the phase factor of the oscillations is observed around a critical pressure of P = 2.5 GPa, suggesting a possible topological phase transition in BaMnSb2.

Summary: Pressure is an efficient tool to tune the electronic structure of iron-based superconductors. Different forms of superconductivity can be induced under high pressure, with Tc values showing a dome shape and the Hall coefficient RH exhibiting nonmonotonic behavior under certain pressures. Additionally, there is a pressure-induced Lifshitz transition of the Fermi surface, possibly responsible for the appearance of superconductivity.
