Monopole-fermion scattering and varying Fock space [PDF]
Journal of High Energy Physics, 2022 We propose a four-dimensional interpretation of the outgoing state of the scattering of a massless fermion off a Dirac monopole. It has been known that such a state has fractional fermion numbers and is necessarily outside the Fock space on top of ...

Bulgarian Journal of Physics, 2020 A general theorem due to Howe of dual action of a classical group and a certain non-associative algebra on a space of symmetric or alternating tensors is reformulated in a setting of second quantization, and familiar examples in atomic and nuclear physics are discussed. The special case of orthogonal–orthogonal duality is treated in detail. It is shown

Generalized Fock space and contextuality. [PDF]
Philos Trans A Math Phys Eng Sci, 2019 This paper is devoted to linear space representations of contextual probabilities—in generalized Fock space. This gives the possibility to use the calculus of creation and annihilation operators to express probabilistic dynamics in the Fock space (in particular, the wide class of classical kinetic equations).

The Fock Space as a De Branges–Rovnyak Space [PDF]
Integral Equations and Operator Theory, 2019 We show that de Branges-Rovnyak spaces include as special cases a number of spaces, such as the Hardy space, the Fock space, the Hardy-Sobolev space and the Dirichlet space. We present a general framework in which all these spaces can be obtained by specializing a sequence that appears in the construction.

Fock-space anatomy of eigenstates across the many-body localization transition [PDF]
Physical review B, 2021 We explore the Fock-space structure of eigenstates across the many-body localisation (MBL) transition in a disordered, interacting quantum spin-1/2 chain.

Toeplitz quantization on Fock space [PDF]
Journal of Functional Analysis, 2018 For Toeplitz operators $T_f^{(t)}$ acting on the weighted Fock space $H_t^2$, we consider the semi-commutator $T_f^{(t)}T_g^{(t)}-T_{fg}^{(t)}$, where $t>0$ is a certain weight parameter that may be interpreted as Planck's constant $\hbar$ in Rieffel's deformation quantization.

Scaling of the Fock-space propagator and multifractality across the many-body localization transition [PDF]
Physical review B, 2022 We implement a recursive Green function method to extract the Fock space (FS) propagator and associated self-energy across the many-body localization (MBL) transition, for one-dimensional interacting fermions in a random onsite potential.

Rare thermal bubbles at the many-body localization transition from the Fock space point of view [PDF]
Physical review B, 2020 In this work we study the many-body localization (MBL) transition and relate it to the eigenstate structure in the Fock space. Besides the standard entanglement and multifractal probes, we introduce the radial probability distribution of eigenstate ...
