Solving Quantum Equations with Gauge Fields: How Explicit Integrators Based on a Bipartite Lattice and Affine Transformations Can Help
2021315
We proposed an explicit numerical integrator consisting of affine transformation pairs resulting from the checkerboard lattice for spatial discretization. It can efficiently solve time evolution equations that describe dynamical quantum phenomena under gauge fields, e.g., generation, motion, interaction of quantum vortices in superconductors or superfluids.

Novel Material Shows Unconventional Superconductivity with Magnetic Order Under Pressure
202133
Multiple superconductivity wad found in the novel spintriplet superconductor UTe_{2}, which is called “Silicon of Quantum Computers”. A complicated spintriplet state is realized as a consequence of spin degree of freedom. This result will lead to a new state of topological superconductivity.

Multiple Superconducting Phases in UTe_{2}: A Complex Analogy to Superfluid Phases of ^{3}He
202133
In quantum liquids, large differences are observed owing to differences in quantum statistics. The physical properties of liquid ^{3}He (Fermion) and ^{4}He (Boson) are considerably different at low temperatures. After the discovery of superconductivity in electron (i.e., Fermion) systems, a similar pairing ordered state was expected for ^{3}He. Remarkably, the observed ordered state of ^{3}He was more surprising than expected, multiple superfluid phases in the T–P phase diagram. The origin of the multiple phases was attributed to ferromagnetic interactions in the pwave symmetry state.
