Quantum spectroscopy of topological dynamics via a supersymmetric Hamiltonian
Hiroshi Yamauchi, Satoshi Kanno, Yuki Sato +4
Topological data analysis (TDA) characterizes complex dynamics through global invariants, but classical computation becomes prohibitive for high-dimensional data. We reinterpret ti…
Pinched geometries in 2D Lorentzian quantum Regge calculus
Yoshiyasu Ito, Daisuke Kadoh, Yuki Sato
We investigate pinched geometries in a two-dimensional Lorentzian model of quantum Regge calculus (QRC) using the tensor renormalization group (TRG) method. A pinched geometry refe…
Inverse design of dual-band valley-Hall topological photonic crystals with arbitrary pseudospin states
Yuki Sato, Shrinathan Esaki Muthu Pandara Kone, Junpei Oba +1
Valley photonic crystals (VPCs) offer topological kink states that ensure robust, unidirectional, and backscattering-immune light propagation. The design of VPCs is typically based…
Properties of the wormhole-dominant phase in two-dimensional quantum gravity
Tsunehide Kuroki, Yuki Sato
We study the Hermitian one-matrix model modified by the double-trace interaction. It is known that the coupling for the double-trace interaction can control the weight…
