The paper proposes "FerBo," a novel superconducting qubit that achieves robustness against both relaxation and dephasing by hybridizing fermionic Andreev levels with a bosonic LC circuit mode while leveraging phase-space wavefunction delocalization similar to fluxonium.
This study reports the discovery of bulk type-II superconductivity with a critical temperature of 4.63 K in the ideal kagome metal LuOs3B2, characterizing its moderately coupled electron-phonon mechanism, enhanced electron correlations, and unique kagome band features such as Dirac points and van Hove singularities through combined experimental measurements and first-principles calculations.
This paper presents an analytic framework that extends the measurement of reactive-load impedance in superconducting transmission-line resonators beyond the perturbative limit, enabling the precise extraction of material properties like the dielectric constant and loss tangent of hexagonal boron nitride without relying on full-wave simulations.
Using DFT+DMFT calculations, this study reveals that doping in bilayer LaNiO induces significant orbital-dependent renormalizations, a Lifshitz transition, and enhanced spin-charge stripe fluctuations, suggesting these correlations are central to its pressure-driven superconductivity.
This paper demonstrates that heteroepitaxial -AlO grown on TiN via pulsed laser deposition forms a high-quality, single-crystal dielectric with an intrinsically low two-level system loss of , establishing it as a promising materials platform for reducing dielectric losses in superconducting quantum circuits.
This paper demonstrates that doping altermagnets within the Hubbard model suppresses long-range antiferromagnetism while preserving strong short-range spin fluctuations, thereby robustly stabilizing and enhancing unconventional superconductivity through a synergistic d-wave and p-wave mixed-pairing state that could lead to higher transition temperatures.
This study demonstrates that applying hydrostatic pressure universally enhances the superconducting transition temperature of (La,Pr)3Ni2O7 thin films and suppresses resistance dips associated with oxygen vacancies, suggesting that pressure-induced electron delocalization at vacancy sites drives the observed Tc increase.
This paper reports the discovery of emergent two-dimensional superconductivity and enhanced non-reciprocal transport phenomena, including a 29% efficient superconducting diode effect, at the molecular beam epitaxy-grown interface between the Dirac semimetal ZrTe and the antiferromagnet FeTe.
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.
