Pair-Density Wave from Doping an Altermagnetic Mott Insulator
Shuai A. Chen, Qianqian Chen, Guangyu Yu +1
Pair-density-wave (PDW) superconductivity is a state in which the superconducting order parameter modulates at a finite wavevector. Using large-scale density matrix renormalization…

Anomalous Coherence Length in Superconductors with Quantum Metric
Jin-Xin Hu, Shuai A. Chen, K. T. Law
The coherence length is the fundamental length scale of superconductors which governs the sizes of Cooper pairs, vortices, Andreev bound states, and more. In BCS theory, the c…
