Ultrafast Demagnetization Through Femtosecond Generation of Non‐Thermal Magnons
Advanced Physics Research, EarlyView.A fully ab initio parametrized model is developed to describe out‐of‐equilibrium magnon dynamics in ferromagnetic metals. Applying this model to ultrafast laser‐induced demagnetization, it is revealed that the generation of non‐thermal magnons provides a sizable demagnetization within 200 fs in excellent comparison with experiments, which establishes ...

On an Axiomatization of Path Integral Quantization and its Equivalence to Berezin's Quantization [PDF]
arXivWe axiomatize path integral quantization of symplectic manifolds. We prove that this path integral formulation of quantization is equivalent to an abstract operator formulation, ie. abstract coherent state (or Berezin) quantization. We use the corresponding path integral of Poisson manifolds to quantize all complete Riemann surfaces of constant non ...

Axion‐Like Interactions and CFT in Topological Matter, Anomaly Sum Rules and the Faraday Effect
Advanced Physics Research, EarlyView.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
Advanced Physics Research, EarlyView.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.

Superconducting Diode Effects: Mechanisms, Materials and Applications
Advanced Physics Research, EarlyView.Superconducting diode effects, nonreciprocal current characteristics of superconductors in the absence of both time reversal and inversion symmetry, exhibit non‐dissipative supercurrent in one direction and ohmic current in the opposite. Abstract Superconducting diode effects (SDEs) generally emerge in superconducting systems where both time‐reversal ...

Quantum Anomalies in Condensed Matter
Advanced Physics Research, EarlyView.Quantum materials provide a fertile ground in which to test and realize quantum anomalies predicted by quantum field theory. Quantum anomalies need to be canceled globally, however, quantum states with a quantum anomaly can exist at the boundary of topological materials.
