Homological Thresholds in Randomly Monitored Quantum Error-Correcting Codes
Yoshito Watanabe, Daiki Sasamoto, Bo Han +1
Random projective measurements are an effective tool to model the interlinked phenomenology of monitoring, inferring, and decoding highly entangled states such as quantum error-cor…
Schwinger boson perturbation theory for spin- Kitaev-Heisenberg magnets: phase diagram and dynamical response near Kitaev spin liquids
Daiki Sasamoto, Joji Nasu
We develop a Schwinger boson perturbative framework for the spin- Kitaev-Heisenberg model. The spin-liquid saddle point of the pure Kitaev model is used as the unperturbed state…
Thermal Hall Signatures of Distinct Schwinger-Boson Flux Sectors on the Honeycomb Lattice
Daiki Sasamoto
Thermal transport offers a bulk probe of charge-neutral excitations in frustrated magnets. It remains challenging, however, to determine whether such transport can distinguish diff…
Chiral bosonic mean-field Ansatz and spin dynamics in spin-1 Kitaev magnets
Daiki Sasamoto, Arnaud Ralko, Jaime Merino +1
The Kitaev model is a paradigmatic system for realizing quantum spin liquids, but its higher-spin extensions are not exactly solvable, and their spin dynamics is less well understo…
Dynamical spin correlations in kagome antiferromagnets: comparison of Abrikosov fermion and Schwinger boson approaches beyond mean field
Daiki Sasamoto, Joji Nasu
Quantum spin liquids exhibit fractionalized spin excitations as a consequence of strong quantum many-body effects. The kagome antiferromagnetic Heisenberg model is a promising cand…
Schwinger boson theory for Kitaev quantum spin liquids
Daiki Sasamoto, Joji Nasu
The Kitaev model is an exactly solvable model with a quantum spin liquid ground state. While this model was originally proposed as an spin model on a honeycomb lattice, ext…
General Formula for the Green's Function Approach to the Spin-1/2 Antiferromagnetic Heisenberg Model
Daiki Sasamoto, Takao Morinari
A wide range of analytical and numerical methods are available to study quantum spin systems. However, the complexity of spin correlations and interactions limits their applicabili…
