Magnetic phase transitions driven by quantum geometry
Chang-geun Oh, Taisei Kitamura, Akito Daido +2
We explore how the quantum geometric properties of the Bloch wave function, characterized by the Hilbert-Schmidt quantum distance, impact magnetic phases in solid-state systems. To…

Anomalous Temperature Dependence of Quantum-Geometric Superfluid Weight
Yuma Hirobe, Taisei Kitamura, Youichi Yanase
The symmetry of Cooper pairs encodes key information about superconductivity and has been widely studied through the temperature dependence of the superfluid weight. However, in sy…

Nonreciprocal Current-Induced Zero-Resistance State in Valley-Polarized Superconductors
Akito Daido, Youichi Yanase, K. T. Law
The recently observed nonreciprocal current-induced zero-resistance state (CIZRS) in twisted trilayer graphene/WSe heterostructure has posed a significant theoretical challenge…
