Axion‐Like Interactions and CFT in Topological Matter, Anomaly Sum Rules and the Faraday Effect
This review investigates the connection between chiral anomalies and their manifestation in topological materials, using both perturbative methods based on ordinary quantum field theory and conformal field theory (CFT). It emphasizes the role of CFT in momentum space for parity‐odd correlation functions, and their reconstruction by the inclusion of a ...

Path Integral Spin Dynamics for Quantum Paramagnets
The study has developed a path integral method, which is a classical approach, combined with atomistic spin dynamics simulations to calculate thermal quantum expectation values. This method can handle Hamiltonians with non‐linear terms, which are important for describing uniaxial anisotropies and mechanical constraints.

Orientation‐Dependent Upper Critical Magnetic Field and Density of State for Uranium Ditelluride
This study investigates the orientation‐dependent upper critical magnetic field (HC2) and the density of states (DOS) in the unconventional superconductor UTe2. These results reveal an anisotropic HC2, with distinct critical fields along different crystallographic axes, highlighting the role of electronic correlations and spin‐triplet pairing.
