  • Code and datasets for 'Theory of potential impurity scattering in pressurized superconducting La3Ni2O7'

    User Collection
    Description:
    Abstract: Recently discovered high-Tc superconductivity in pressurized bilayer nickelate La3Ni2O7 (La- 327) is likely driven by the non-phononic repulsive interaction. Depending on the interlayer repul- sion strength, the superconducting gap structure is expected to be either d-wave or sign-changing bonding-antibonding s±-wave. Unfortunately, conventional spectroscopic probes of the gap struc- ture are impractical due to the high-pressure requirement. We propose studying the effect of point- like non-magnetic impurities to distinguish these symmetries, which can be achieved by electron irradiation before applying pressure. Here, we theoretically predict conventional suppression for d-wave superconductivity, whereas the suppression for the interlayer s±-wave state depends subtly on the asymmetry of bonding and antibonding subspaces. For the predicted electronic structure of La-327, the s±-wave is more robust, with Tc showing a convex-to-concave transition, indicating a crossover to s++-wave symmetry as impurity concentration increases. We further analyze the sensitivity of these findings to potential electronic structure modifications.

  • Artifacts: "Only as Strong as the Weakest Link": On the Security of Brokered Single Sign-On on the Web

    User Collection
    Description:
    Single Sign-On (SSO) is an authentication process that allows users to access multiple services with a single set of login credentials. Although SSO improves the user experience, it poses challenges to developers to implement complex authentication protocols securely. External services, called brokers, simplify the integration of SSO. In this paper, we shed light on the emerging brokered SSO ecosystem, focusing on the security of the newly introduced actor, the broker. We systematically evaluate the landscape of brokered SSO, uncovering significant blind spots in previous research. Our study reveals that 25% of the websites with SSO integrate brokers for authentication, an area that has not been covered by any previous research. Through our comprehensive security evaluation, we identify three categories of threats associated with brokered SSO: (1) insufficient validation of redirect chains enabling injection attacks, (2) unauthorized data access enabling account takeovers, and (3) violations of security best current practices. We expose vulnerabilities in over 50 brokers, compromising the security of more than 2k websites. These findings represent only a lower bound of a critical situation, underscoring the urgent need for improved security measures and protocols to safeguard the integrity of brokered SSO systems.
