Geometric Quantum Thermodynamic Engine under an Isothermal Operation: An Application of a Thouless Pumping
Ryosuke Yoshii, Hisao Hayakawa
The paper demonstrates that a cyclically driven open quantum system can act as an isothermal engine by extracting work from the geometry of its steady-state manifold, rather than f…
Phase Transitions and Noise Robustness of Quantum Graph States
Tatsuya Numajiri, Shion Yamashika, Tomonori Tanizawa +3
Graph states are entangled states that are essential for quantum information processing. As experimental advances enable the realization of large-scale graph states, efficient fide…
Topological Filtering and Emergent Kondo Scale
Ryosuke Yoshii, Rio Oto
We study the Kondo effect induced by a topological soliton in a one-dimensional Dirac system with the sign-changing mass term. The soliton hosts a localized zero mode whose spatial…
Topological-Mass Control of an Emergent Kondo Scale in an Interacting SSH Chain
Ryosuke Yoshii, Rio Oto
Topological bound states emerging at domain walls of dimerized chains provide a robust platform for exploring correlation effects beyond single-particle physics. When such a solito…
Simulating Quantum Field Theories with Boundaries in Curved Spacetimes Using Open Spin Systems
Shunichiro Kinoshita, Keiju Murata, Daisuke Yamamoto +1
We develop a framework to simulate quantum field theories (QFTs) with boundaries in -dimenmsional curved spacetimes by employing open spin systems. Building upon our previou…
Inhomogeneous entanglement structure in monoaxial chiral ferromagnetic quantum spin chain
Kentaro Nishimura, Ryosuke Yoshii
Chiral magnets, characterized by inhomogeneous magnetic moment arrangements, have attracted significant attention recently due to their topological orders, such as magnetic skyrmio…
