The Configuration Interaction Method in the Second Quantization Representation

, 1971
The mathematical apparatus of the second quantization is applied to the configuration interaction method. The configurations are treated as a system of particles and holes against the vacuum state built by the closed shell of the ground configuration.

Index theory and second quantization of boundary value problems

, 1992
The second quantization functor associates to each skew-symmetric operator in one-particle space a derivation δ of the algebra which is based on the given commutation relations.

Hamiltonian BRST and Batalin-Vilkovisky formalisms for second quantization of gauge theories

, 2005
Gauge theories that have been first quantized using the Hamiltonian BRST operator formalism are described as classical Hamiltonian BRST systems with a BRST charge of the form (Ψ, ΩΨ)even and with natural ghost and parity degrees for all fields.

Second Quantization and Evolution Operators in infinite dimension

In an infinite dimensional separable Hilbert space $X$, we study compactness properties and the hypercontractivity of the Ornstein-Uhlenbeck evolution operators $P_{s,t}$ in the spaces $L^p(X,γ_t)$, $\{γ_t\}_{t\in\R}$ being a suitable evolution system of measures for $P_{s,t}$. Moreover, we study the asymptotic behavior of $P_{s,t}$.

AI‐Assisted Digital Single‐Molecule Activity Tracker for Decoupling Intrinsic Heterogeneity from Photo‐Oxidative Damage in High‐Photon‐Flux Enzymology

Advanced Science, EarlyView.
Employing a digital single‐molecule activity tracker (dSMAT), this research demonstrates that high‐photon‐flux irradiation drives progressive oxidative scarring in polymerases. Unlike simple thermal denaturation, real‐time kinetic tracking dynamically visualizes enzymes degrading into multiple impaired subpopulations.
