TRIQS/Nevanlinna: Implementation of the Nevanlinna Analytic Continuation method for noise-free data
Sergei Iskakov, Alexander Hampel, Nils Wentzell +1
We present the TRIQS/Nevanlinna analytic continuation package, an efficient implementation of the methods proposed by J. Fei et al in [Phys. Rev. Lett. 126, 056402 (2021)] and [Phy…
Dielectric environment sensitivity of carbon centres in hexagonal boron nitride
Danis I. Badrtdinov, Carlos Rodriguez-Fernandez, Magdalena Grzeszczyk +11
A key advantage of utilizing van der Waals materials as defect-hosting platforms for quantum applications is the controllable proximity of the defect to the surface or the substrat…
Conductivity of infinite-layer NdNiO as a probe of spectator bands
Harrison LaBollita, Alexander Hampel, Jonathan Karp +2
Using a density-functional theory plus dynamical mean-field theory methodology, we compute the many-body electronic structure and optical conductivity of NdNiO under the infl…
Orbital polarization, charge transfer, and fluorescence in reduced valence nickelates
M. R. Norman, A. S. Botana, J. Karp +6
This paper presents a simple formalism for calculating X-ray absorption (XAS) and resonant inelastic x-ray scattering (RIXS) that has as input orbital-resolved density of states fr…
Low rank Green's function representations applied to dynamical mean-field theory
Nan Sheng, Alexander Hampel, Sophie Beck +4
Several recent works have introduced highly compact representations of single-particle Green's functions in the imaginary time and Matsubara frequency domains, as well as efficient…
