Stochastic integration in Fock space [PDF]
Pacific Journal of Mathematics, 1986 This paper uses elementary Hilbert-space techniques to construct an analogue of the Itô integral, the 'integral' taking values in the symmetric Fock space of a direct integral \(\bar {\mathcal H}\) of Hilbert spaces over the real line. (The case \(\bar {\mathcal H}=L^ 2[0,\infty)\) yields the classical Itô integral.) An explicit formula is obtained for

Embedding qubits into fermionic Fock space: Peculiarities of the four-qubit case [PDF]
, 2015 We give a fermionic Fock space description of embedded entangled qubits. Within this framework the problem of classification of pure state entanglement boils down to the problem of classifying spinors. The usual notion of separable states turns out to be

Affine Yangian Action on the Fock Space [PDF]
Publications of the Research Institute for Mathematical Sciences, 2015 The localized equivariant homology of the quiver variety of type $A_{N-1}^{(1)}$ can be identified with the level one Fock space by assigning a normalized torus fixed point basis to certain symmetric functions, Jack($\mathfrak{gl}_N$) symmetric functions

Chemistry – A European Journal, EarlyView.The energetics of the addition reaction of P‐centered radicals onto alkenes are primarily ruled by the stability of the attacking radical, as outlined by the computational screening of a wide range of reactions. In addition, donor‐acceptor substituents at the olefin have an important tuning role.

Uncertainty principles for the Fock space [PDF]
, 2015 In this note, we prove several versions of the uncertainty principle for the Fock space F 2 in the complex plane. In particular, for any unit vector f in F 2, we show that dist( f + zf , [ f ])dist( f - zf , [ f ])≥1, where [ f ]=C f is the one ...

The Huang–Yang Formula for the Low‐Density Fermi Gas: Upper Bound
Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT We study the ground state energy of a gas of spin 1/2$1/2$ fermions with repulsive short‐range interactions. We derive an upper bound that agrees, at low density ϱ$\varrho$, with the Huang–Yang conjecture. The latter captures the first three terms in an asymptotic low‐density expansion, and in particular the Huang–Yang correction term of order

Many-body localization in the Fock space of natural orbitals
SciPost Physics, 2018 We study the eigenstates of a paradigmatic model of many-body localization in the Fock basis constructed out of the natural orbitals. By numerically studying the participation ratio, we identify a sharp crossover between different phases at a disorder

Contributions to Plasma Physics, EarlyView.ABSTRACT Warm dense matter (WDM) is a complex state, where quantum effects, thermal excitations, and strong interparticle correlations coexist. Understanding its microscopic composition and medium‐induced modifications of atomic and molecular properties is essential for planetary modeling, fusion research, and high‐energy‐density experiments.
