Enhancing the electron pair approximation with measurements on trapped-ion quantum computers
npj Quantum InformationThe electron pair approximation offers an efficient variational quantum eigensolver (VQE) approach for chemistry simulations on quantum computers. With the number of entangling gates scaling quadratically with system size and a constant measurement ...

Heterogeneous Pair Approximation of Methanol Oxidation on TiO2 Reveals Two Reaction Pathways
, 2021 We propose a novel method to simulate the chemical kinetics of methanol oxidation on the rutile TiO2(110) surface. This method must be able to capture the effects of static disorder (site-to-site variations in the rate constants), as well as dynamic ...

Collective excitations of a charged Fermi superfluid in the BCS-BEC crossover
New Journal of Physics, 2023 We consider collective excitations in the superfluid state of Fermi condensed charged gases. The dispersion and damping of collective excitations at nonzero temperatures are examined, and the coexistence and interaction of different branches of ...

From deformed Hartree-Fock to the nucleon-pair approximation
Physics Letters B, 2020 The nucleon-pair approximation (NPA) can be a compact alternative to full configuration-interaction (FCI) diagonalization in nuclear shell-model spaces, but selecting good pairs is a long-standing problem.

Approximation multivariate distribution of main indices of tehran stock exchange with pair-copula [PDF]
, 2013 The multivariate distribution of five main indices of Tehran stock exchange is approximated using a pair-copula model. A vine graphical model is used to produce an n-dimensional copula.

Higher fidelity simulations of nonlinear Breit–Wheeler pair creation in intense laser pulses
European Physical Journal C: Particles and Fields, 2022 When a photon collides with a laser pulse, an electron-positron pair can be produced via the nonlinear Breit–Wheeler process. A simulation framework has been developed to calculate this process, which is based on a ponderomotive approach that includes ...

Collective pairing hamiltonian in the GCM approximation [PDF]
Nuclear Physics A, 1985 Abstract Using the generator coordinate method and the gaussian overlap approximation we derived the collective Schrodinger-type equation starting from a microscopic single-particle plus pairing hamiltonian for one kind of particle. The BCS wave function was used as the generator function.
