Polaron-mediated metal-insulator transition and proton conduction in hydrogenated nickelate perovskites
Hang Ma, Tianxing Ma, Ying Liang
Nickel-based perovskites, owing to their spontaneous hydrogen uptake and the dramatic increase in resistivity upon hydrogenation, have emerged as promising candidates for proton-co…
Tuning superconducting pairing symmetry via a staggered potential in the doped honeycomb Hubbard model
Yanmei Cai, Yicheng Xiong, Ying Liang +1
The ability to control superconducting pairing symmetry is crucial for designing unconventional and topological superconductors, yet practical tuning parameters beyond chemical dop…
Role of small-radius and high-electronegativity A-Site dopants in enhancing proton transport and stability of perovskite electrolytes
Hang Ma, Ying Liang, Tianxing Ma
The paper uses first‑principles calculations to show that small, highly electronegative A‑site dopants such as Ca improve both proton conductivity and chemical stability in BaCeO₃…
Stripe-Ordered Altermagnetism Emerging from Correlation-Driven Spin-Density-Wave Instability
Zenghui Fan, Jingyao Meng, Tianxing Ma
The paper investigates how a spin-density-wave instability in a Hubbard model for iron pnictides can give rise to a stripe‑ordered altermagnetic insulating phase, using Hartree‑Foc…
Interplay of magnetic and thermodynamic responses in the kagome-triangular system
Zixuan Jia, Lufeng Zhang, Qingzhuo Duan +5
Inspired by the recent experimental progress in pyrochlore derivative RESbAO (A = Mg, Zn), we investigate the Hubbard model on the kagome lattice with an additio…
Time-reversal symmetry breaking superconductivity in the presence of loop-current fluctuations
Zenghui Fan, Runyu Ma, Stefano Chesi +2
Loop currents have been proposed in various superconductors and recently confirmed in kagome materials, raising a fundamental question regarding their intrinsic connection to super…
