Layer-Asymmetry-Induced Topological Superconductivity in High-T Bilayer Nickelates
Zhongyi Zhang, Congcong Le, Hoi Chun Po +3
The recent discovery of high-T superconductivity in bilayer nickelates has highlighted the crucial role of interlayer coupling and motivated proposals for dominant interlayer p…
Ising Dirac fermions across a topological phase transition
Aoqian Zhang, Yaqi Ma, Yifei Jin +14
Dirac fermions have attracted significant interest due to their relativistic dispersions and close connections to topological physics, yet they are generally expected to be gapped…
Peak-valley mechanism for Hilbert space fragmentation
Jianlong Fu, Hoi Chun Po
Ergodicity breaking in isolated systems has emerged as an important frontier in the study of quantum many-body physics. While generic Hamiltonians are expected to obey the eigensta…
Toward bootstrapping tensor-network contractions
Seishiro Ono, Yanbai Zhang, Hoi Chun Po
Accurate contraction of tensor networks beyond one dimension is essential in various fields including quantum many-body physics. Existing approaches typically rely on approximate c…
Moire driven edge reconstruction in Fractional quantum anomalous Hall states
Feng Liu, Hoi Chun Po, Xue-Yang Song
We investigate fractional edge modes in moire fractional quantum anomalous Hall states, focusing on the role of lattice momentum conservation and umklapp scattering. For the hierar…
Catalog of phonon emergent particles and chiral phonons: Symmetry-based classification and materials database investigation
Houhao Wang, Dongze Fan, Hoi Chun Po +2
Chirality and topology are fundamental and ubiquitous in nature. Symmetry has proven to be a powerful tool for predicting topological phonons. However, to date, topological phonon…
