Shear coordinates on the super Teichmüller space

, 2013
Dans cette thèse nous étudions un super-analogue de l'espace de Teichmüller des surfaces à trous. Le but de notre étude est la construction sur cet espace de coordonnées analogues aux coordonnées de décalage de Thurston-Bonahon-Fock-Penner.

Bosonic near-CFT1 models from Fock-space fluxes

Journal of High Energy Physics
We construct a family of near-CFT1 models with a conserved U(1) charge, whose basic degrees of freedom are canonical bosons. The Sachdev-Ye-Kitaev (SYK) model — the first microscopic model that realizes the near-CFT1 dynamics — is based on random p-local

Quantum de Sitter Geometry

Universe
Quantum de Sitter geometry is discussed using elementary field operator algebras in Krein space quantization from an observer-independent point of view, i.e., ambient space formalism.

Numerical Ranges of Normal Weighted Composition Operators on the Fock Space of CN

Journal of Function Spaces, 2018
Numerical ranges of normal weighted composition operators on the Fock space of CN are completely characterized. The main result shows that numerical ranges of such operators are closely related to their composition symbols.

Hilbert spaces of symmetric analytical functions on $\ell_{1}$

Karpatsʹkì Matematičnì Publìkacìï, 2013
We consider completions of the space of symmetric polynomials on $\ell_{1}$ with respect to some Hilbert norm and investigate conditions under which the obtained spaces consist of analytic functions with domains in $\ell_{1}$.

A hyperdeterminant on fermionic Fock space

Annales de l’Institut Henri Poincaré D, Combinatorics, Physics and their Interactions
Twenty years ago, Cayley's hyperdeterminant, the degree four invariant of the polynomial ring \mathbb{C}[\mathbb{C}^2\otimes\mathbb{C}^2\otimes \mathbb{C}^2]^{{\operatorname{SL}_2(\mathbb{C})}^{\times 3}} , was popularized in modern physics as it separates genuine entanglement classes in

Seniority‐Zero Quadratic Canonical Transformation Theory

International Journal of Quantum Chemistry, Volume 126, Issue 12, June 15, 2026.
We construct a unitary transformation of electronic Hamiltonians using quadratic canonical transformation theory, choosing the transformation to minimize the non‐seniority‐zero elements of the transformed Hamiltonian. This allows us to add dynamic correlation to the static correlation inherent in orbital‐optimized doubly‐occupied (seniority‐zero ...

A 50‐Year Historical Perspective of the Extended Koopmans' Theorem, Its Exactness, and Future Prospects

International Journal of Quantum Chemistry, Volume 126, Issue 13, July 5, 2026.
The early history of the extended Koopmans' theorem is reviewed. The history of studies of its exactness for ionization is discussed, as well as limits of accuracy for electron affinities. The extended Koopmans' theorem will be useful in obtaining Dyson orbitals for application in studies of chemical reactivity.

White noise calculus and Fock space

, 1994
White Noise Calculus is a distribution theory on Gaussian space, proposed by T. Hida in 1975. This approach enables us to use pointwise defined creation and annihilation operators as well as the well-established theory of nuclear space.This self ...
