Towards complete characterization of topological insulators and superconductors: A systematic construction of topological invariants based on Atiyah-Hirzebruch spectral sequence
Seishiro Ono, Ken Shiozaki
The past decade has witnessed significant progress in topological materials investigation. Symmetry-indicator theory and topological quantum chemistry provide an efficient scheme t…
Atiyah-Hirzebruch spectral sequence for topological insulators and superconductors: pages for 1651 magnetic space groups
Ken Shiozaki, Seishiro Ono
We compute the pages of the momentum-space and real-space Atiyah-Hirzebruch spectral sequence (AHSS) for topological crystalline insulators and superconductors up to three sp…
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…
Frustration-free free fermions
Seishiro Ono, Rintaro Masaoka, Haruki Watanabe +1
We develop a general theory of frustration-free free-fermion systems and derive the necessary and sufficient conditions for such Hamiltonians. Assuming locality and translation inv…
Frustration-free free fermions and beyond
Rintaro Masaoka, Seishiro Ono, Hoi Chun Po +1
Frustration-free Hamiltonians provide pivotal models for understanding quantum many-body systems. In this paper, we establish a general framework for frustration-free fermionic sys…
Unitary network: Tensor network unitaries with local unitarity
Wenqing Xie, Seishiro Ono, Hoi Chun Po
We introduce unitary network, an oriented architecture for tensor network unitaries. Compared to existing architectures, in a unitary network each local tensor is required to be a…
