Branched polymers with loops coupled to the critical Ising model
Jan Ambjørn, Yukimura Izawa, Yuki Sato
We study the continuum limit of branched polymers (BPs) with loops coupled to Ising spins at the zero-temperature critical point. It is known that the continuum partition function…
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…
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…
Optimizing a parameterized controlled gate using Free Quaternion Selection
Hiroyoshi Kurogi, Katsuhiro Endo, Yuki Sato +6
In variational quantum algorithms, parameterization is typically applied to single-qubit gates.In this study, we instead parameterize a generalized controlled gate and propose an a…
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…
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…
