Quantum Computational Materials Science

Tsuchiura research group

About us

Established in October 2023, our group specializes in the theoretical study of superconductors and magnetic materials with topological quantum states, based on theoretical physics and quantum computational methods. Current research areas include topological superconductivity with broken spatial symmetries, the analysis of anomalous transport properties in magnetic topological materials, and the application of the VQE algorithm to the study of strongly correlated superconductors.

Research interests

Superconductivity:
- novel superconducting states with broken symmetries in the doped Kitaev model
- Anomalous Josephson effects and diode effects in topological superconducting ladder systems
- the pseudogap state in cuprate superconductors
Magnetic properties and novel transport phenomena in rare-earth intermetallics:
- transverse thermoelectric effects inSmCo5
- spin reorientation phenomena and transverse thermoelectric effects in DyCo5
Magnetic materials data science with ab-initio calculations:
- magnetic materials research based on data assimilation method and ab-initio calculations
Quantum computations for strongly correlated electronic systems:
- hybrid quantum-classical computing approach for strongly correlated superconducting states
