The path integral representation kernel of evolution operator in Merton-Garman model
In the framework of path integral the evolution operator kernel for the Merton-Garman Hamiltonian is constructed. Based on this kernel option formula is obtained, which generalizes the well-known Black-Scholes result.

On reciprocal degree distance of graphs
Given a connected graph H, its reciprocal degree distance is defined asRDD(H)=∑x≠ydH(vx)+dH(vy)dH(vx,vy), where dH(vx) denotes the degree of the vertex vx in the graph H and dH(vx,vy) is the shortest distance between vx and vy in H.

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.

Abstract Short‐lived, unobservable, and not subject to the usual rules of conservation of energy and momentum, virtual particles—an integral part of the conceptual framework of quantum field theory (QFT)—exhibit a number of curious characteristics which, in recent decades, have in part fueled important discussions about their ontological status ...

In‐Situ EPR Study of the Effect of SO2 Poisoning and Regeneration of Cu‐CHA Catalysts
In‐situ electron paramagnetic resonance highlights and quantifies the changes in the redox properties of copper chabazite catalysts for the SCR reaction after poisoning with SO2 and after regeneration at high temperature. Abstract A series of copper (Cu) exchanged chabazite zeolite with different Cu content were investigated to elucidate the effect of ...
