This study utilizes microwave magnetotransport measurements on FeSeTe epitaxial films to characterize flux flow resistivity and derive the orbital upper critical field, revealing multiband superconductivity features consistent with a two-band model characterized by strong intraband and weak interband coupling.
By utilizing ionic liquid gating on homoepitaxial SrTiO thin films, researchers achieved a superconducting transition temperature of up to 503 mK and observed consistent BCS scaling and paraconductivity behavior, marking a significant improvement over similar systems on single-crystal substrates.
This paper proposes that the enigmatic pseudogap state in cuprates, characterized by Fermi arcs and reduced carrier density, originates from a structural reconstruction that introduces a symmetry-enforced sublattice degree of freedom, which, when combined with spin-orbit coupling, naturally explains these experimental signatures through Fermi surface reconstruction and matrix-element interference.
This perspective article discusses theoretically proposed coincidence detection techniques designed to directly measure two-body correlations in strongly correlated electron systems, highlighting their potential to unravel fundamental puzzles such as unconventional superconductivity and quantum spin liquids while advancing the study of novel quantum phenomena.
This paper extends the functional renormalization group to two-dimensional surfaces of three-dimensional systems, revealing that while surface physics typically dominates, intermediate interlayer couplings can induce a transition from superconductivity to incommensurate spin-density-wave and spin-bond orders, potentially enabling chiral spin-bond order.
This paper explains how the interplay between Zeeman fields and Ising spin-orbit coupling generates stabilizing even-frequency spin-triplet pairs that counteract destabilizing odd-frequency pairs, thereby enabling spin-singlet superconductivity in monolayer transition-metal dichalcogenides to persist beyond the Pauli limit and exhibit magnetic field anisotropy.
This paper presents a holistic computational model that simulates radiation-induced correlated errors on superconducting quantum devices to evaluate and optimize the performance of quantum error correction codes and chip design mitigation strategies.
This paper demonstrates that Sn-InAs nanowire transmons exhibit gate-tunable anharmonicity ranging from the charging energy down to values smaller than , a behavior that surpasses the short-junction model's lower limit while maintaining coherent qubit operation.
This study demonstrates that epitaxially grown LaNiO thin films can be tuned from Fermi liquid-like to non-Fermi liquid behavior under modest hydrostatic pressures, suggesting a strong proximity to a fluctuating ordered state that requires significantly less pressure than in bulk single crystals.
This paper proposes a unified theoretical framework integrating quantum electrodynamics, causal set theory, and AdS/CFT holographic duality to explain how quantum vacuum resonance induces macroscopic coherence in quantum materials, offering a novel mechanism for high-temperature superconductivity and testable protocols for controlling quantum phase transitions.
