Alchemical perturbation density functional theory
Physical Review Research, 2020 We introduce an orbital-free electron density functional approximation based on alchemical perturbation theory. Given convergent perturbations of a suitable reference system, the accuracy of popular self-consistent Kohn-Sham density functional estimates ...

Chiral Perturbation Theory [PDF]
Annual Review of Nuclear and Particle Science, 2007 This review gives a brief introduction to chiral perturbation theory in its various settings. We discuss some applications of recent interest, including chiral extrapolations for lattice gauge theory.

Amplitude/operator basis in chiral perturbation theory
Journal of High Energy Physics, 2023 We establish a systematic construction of the on-shell amplitude/operator basis for Chiral Perturbation Theory (ChPT) in D = 4 spacetime dimensions and with an arbitrary number of flavors N f .

Positivity of hexagon perturbation theory
Journal of High Energy Physics, 2018 The hexagon-form-factor program was proposed as a way to compute three-and higher-point correlation functions in N = 4 $$ \mathcal{N}=4 $$ super-symmetric Yang-Mills theory and in the dual AdS5×S5 superstring theory, by exploiting the integrability of ...

SMD-based numerical stochastic perturbation theory
European Physical Journal C: Particles and Fields, 2017 The viability of a variant of numerical stochastic perturbation theory, where the Langevin equation is replaced by the SMD algorithm, is examined. In particular, the convergence of the process to a unique stationary state is rigorously established and ...

Many-Body Perturbation Theories for Finite Nuclei
Frontiers in Physics, 2020 In recent years many-body perturbation theory encountered a renaissance in the field of ab initio nuclear structure theory. In various applications it was shown that perturbation theory, including novel flavors of it, constitutes a useful tool to ...
