Many-body quantum chaos in excitonic spectra from first principles
Daniel Hernangómez-Pérez, Rafael A. Molina
We demonstrate that realistic excitonic many-body Hamiltonians obtained from first-principles GW-Bethe-Salpeter equation calculations can exhibit quantum chaos governed by random-m…
Efficient band structure calculations using Gaussian basis functions and application to atomically thin transition-metal dichalcogenides
Rémi Pasquier, María Camarasa-Gómez, Anna-Sophia Hehn +2
We present a space-time algorithm for periodic systems in a Gaussian basis including spin-orbit coupling. We employ lattice summation to compute the irreducible density respon…
Generalized many-body exciton g-factors: magnetic hybridization and non-monotonic Rydberg series in monolayer WSe
Paulo E. Faria Junior, Daniel Hernangómez-Pérez, Tomer Amit +2
Magneto-optics of low dimensional semiconductors, such as monolayer transition metal dichalcogenides, offers a vast playground for exploring complex quantum phenomena. However, cur…
Roadmap on Advancements of the FHI-aims Software Package
Joseph W. Abbott, Carlos Mera Acosta, Alaa Akkoush +203
Electronic-structure theory is the foundation of the description of materials including multiscale modeling of their properties and functions. Obviously, without sufficient accurac…
Molecular Transport
María Camarasa-Gómez, Daniel Hernangómez-Pérez, Jan Wilhelm +2
Single-molecule junctions - nanoscale systems where a molecule is connected to metallic electrodes - offer a unique platform for studying charge, spin and energy transport in non-e…
Designable exciton mixing through layer alignment in WS-graphene heterostructures
Amir Kleiner, Daniel Hernangómez-Pérez, Sivan Refaely-Abramson
Optical properties of heterostructures composed of layered 2D materials, such as transition metal dichalcogenides (TMDs) and graphene, are broadly explored. Of particular interest…
Charge quenching at defect states in transition metal dichalcogenide-graphene van der Waals heterobilayers
Daniel Hernangómez-Pérez, Andrea Donarini, Sivan Refaely-Abramson
We study the dynamical properties of point-like defects, represented by monoatomic chalcogen vacancies, in WS-graphene and MoS-graphene heterobilayers. Employing a multidis…
Spin-defect characteristics of single sulfur vacancies in monolayer
Alexander Hötger, Tomer Amit, Julian Klein +15
Single spin defects in 2D transition-metal dichalcogenides are natural spin-photon interfaces for quantum applications. Here we report high-field magneto-photoluminescence spectros…
Tunable magneto-optical properties in MoS via defect-induced exciton transitions
Tomer Amit, Daniel Hernangómez-Pérez, Galit Cohen +2
The presence of chalcogen vacancies in monolayer transition metal dichalcogenides (TMDs) leads to excitons with mixed localized-delocalized character and to reduced valley selectiv…
Quartic multifractality and finite-size corrections at the spin quantum Hall transition
Martin Puschmann, Daniel Hernangómez-Pérez, Bruno Lang +2
The spin quantum Hall (or class C) transition represents one of the few localization-delocalization transitions for which some of the critical exponents are known exactly. Not know…
