This study combines experimental transport measurements and theoretical calculations to reveal that UTe2 possesses a rectangular, anisotropically warped Fermi surface where electron-hole scattering dichotomy, driven by low-dimensional antiferromagnetic fluctuations, highlights the dominant role of electron pockets in its spin-triplet superconductivity.
This study demonstrates that controlled non-magnetic disorder induced by electron irradiation can suppress the charge-density wave order in single crystals, driving the system from a Fermi liquid to a non-Fermi liquid regime and refining the location of its non-magnetic quantum critical point to the composition range of –$0.85$.
This study reports the discovery of pressure-induced superconductivity in non-stoichiometric AgSbTe2, which emerges at a low pressure of 0.38 GPa and reaches a maximum critical temperature of 7.4 K during decompression, driven by an enhanced electronic density of states at the Fermi level.
By utilizing pulse-echo ultrasound to identify a previously hidden re-entrant phase transition characterized by an upward jump in sound velocity, this study resolves the thermodynamic paradox of UTe's phase diagram by establishing a tetracritical point and confirming the existence of a multi-component superconducting state driven by the competition and locking of distinct order parameters.
This paper reviews the emerging field of quantum-material Josephson junctions, highlighting how replacing passive barriers with magnetic, correlated, or ferroelectric materials transforms these devices into active probes of many-body physics and enables novel functionalities like nonreciprocal transport, field-free diode effects, and superconducting memory.
This study investigates the dynamic response of trapped magnetic flux in superconducting discs to stepwise external field changes, revealing a direct correlation where 600 G steps induce 40–50% flux variations that may cause energy dissipation and heating, while also characterizing the flux profile's surface roughness through scaling analysis.
This study presents a data-driven framework integrating a novel machine-learning model (BEE-NET) with a multi-stage AI-accelerated workflow to efficiently screen millions of candidates, successfully identifying and experimentally confirming two new superconducting compounds.
This paper demonstrates that in hybrid superconductor-hole systems, the opposite mass signs between subsystems can paradoxically suppress proximity-induced superconductivity by enhancing insulating gaps at subband anticrossings, leading to a characteristic anomalous Josephson effect that is crucial for designing robust quantum computing platforms.
This paper investigates how 8-fermion interactions in effective field theories analogous to BCS theory can lead to either modified second-order phase transitions with non-standard gap temperature dependencies or entirely new first-order phase transitions, depending on the parameter space.
Using variational Monte Carlo calculations, this study demonstrates that topological chiral superconducting states driven by strong repulsive Coulomb interactions are energetically favored over Fermi liquid phases in rhombohedral graphene systems with specific dispersion relations, revealing a new mechanism for superconductivity that does not rely on conventional Fermi surface pairing instabilities.
