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…
Quantum signal processing in Hilbert space fragmented systems
Naoya Egawa, Kaoru Mizuta, Joji Nasu
Quantum signal processing (QSP), originally developed for composite pulse sequences in nuclear magnetic resonance systems, has recently attracted attention as a unified framework f…
Formulation of intrinsic nonlinear thermal conductivity for bosonic systems using quantum kinetic equation
Aoi Kuwabara, Joji Nasu
Nonlinear responses in transport phenomena have attracted significant attention because they can arise even when linear responses are forbidden by symmetry, with the quantum geomet…
Controlling discrete time crystals via single-site operations in zero-field diamond quantum simulators
Naoya Egawa, Kaoru Mizuta, Joji Nasu
Discrete time crystals (DTCs) have emerged as novel nonequilibrium phases of matter that spontaneously break discrete time-translation symmetry in periodically driven systems. Rigo…
Nonlocal correlations in quantum energy teleportation: perspectives from their Majorana representations and information thermodynamics
Hiroaki Matsueda, Yusuke Masaki, Kanji Itoh +2
Motivated by anomalous nonlocal correlation in the Kitaev spin liquids, we propose a quantum energy teleportation protocol between remote partners Alice and Bob on a quantum spin m…
Real-time control of non-Abelian anyons in Kitaev spin liquid under energy dissipation
Chihiro Harada, Atsushi Ono, Joji Nasu
Quantum spin liquids realized in the Kitaev model offer a platform for fractionalization of spin into two quasiparticles: itinerant Majoranas and localized visons. Introducing a un…
