A note on Haag duality

open access: yesNuclear Physics B, 2022
Haag duality is a remarkable property in QFT stating that the commutant of the algebra of observables localized in some region of spacetime is exactly the algebra associated to the causally disconnected region.

Second-Quantized Fermionic Operators with Polylogarithmic Qubit and Gate Complexity

open access: yesPRX Quantum, 2022
We present a method for encoding second-quantized fermionic systems in qubits when the number of fermions is conserved, as in the electronic structure problem. When the number $F$ of fermions is much smaller than the number $M$ of modes, this symmetry reduces the number of information-theoretically required qubits from $Θ(M)$ to $O(F\log M)$.

JT gravity at finite cutoff

open access: yesSciPost Physics, 2020
We compute the partition function of 2D Jackiw-Teitelboim (JT) gravity at finite cutoff in two ways: (i) via an exact evaluation of the Wheeler-DeWitt wavefunctional in radial quantization and (ii) through a direct computation of the Euclidean path ...

Spin-resolved transport physics induced by a Majorana-fermion zero mode

open access: yesAIP Advances, 2019
By using the Hubbard operator Green’s function method, the spin-resolved transport properties of a quantum dot coupled to metallic leads and side-coupled to a topological superconductor wire hosting Majorana bound states (MBSs) are studied theoretically.

Spin-other-orbit Operator in the Tensorial Form of Second Quantization [PDF]

open access: yesPhysica Scripta, 1998
The tensorial form of the spin-other-orbit interaction operator in the formalism of second quantization is presented. Such an expression is needed to calculate both diagonal and off-diagonal matrix elements according to an approach, based on a combination of second quantization in the coupled tensorial form, angular momentum theory in three spaces ...

Vacuum and Spacetime Signature in the Theory of Superalgebraic Spinors

open access: yesUniverse, 2019
A new formalism involving spinors in theories of spacetime and vacuum is presented. It is based on a superalgebraic formulation of the theory of algebraic spinors.

spo(2|2)-Equivariant Quantizations on the Supercircle S^{1|2}

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2013
We consider the space of differential operators $mathcal{D}_{lambdamu}$ acting between$lambda$- and $mu$-densities defined on $S^{1|2}$ endowed with its standard contact structure.This contact structure allows one to define a filtration on $mathcal{D}_ ...

AUTOMATIC RECTIFICATION OF BUILDING FAÇADES [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017
Focusing mainly on the case of (near-)planar building façades, a methodology for their automatic projective rectification is described and evaluated. It relies on a suitably configured, calibrated stereo pair of an object expected to contain a minimum of

Models of Quadratic Algebras Generated by Superintegrable Systems in 2D

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2011
In this paper, we consider operator realizations of quadratic algebras generated by second-order superintegrable systems in 2D. At least one such realization is given for each set of Stäckel equivalent systems for both degenerate and nondegenerate ...
