Theory of EELS in atomically thin metallic films
A. Rodríguez Echarri, Enok Johannes Haahr Skjølstrup, Thomas G. Pedersen +1
We study strongly confined plasmons in ultrathin gold and silver films by simulating electron energy-loss spectroscopy (EELS). Plasmon dispersion relations are directly retrieved f…
Finite-difference time-domain simulation of strong-field ionization: Perfectly matched layer approach
Høgni C. Kamban, Sigurd S. Christensen, Thomas Søndergaard +1
A Finite-Difference Time-Domain (FDTD) scheme with Perfectly Matched Layers (PMLs) is considered for solving the time-dependent Schrödinger equation, and simulate the ionization of…
Excitonic magneto-optics in monolayer transition metal dichalcogenides: From nanoribbons to two-dimensional response
J. Have, N. M. R. Peres, T. G. Pedersen
The magneto-optical response of monolayer transition metal dichalcogenides (TMDs), including excitonic effects, is studied using a nanoribbon geometry. We compute the diagonal opti…
Field-induced dissociation of two-dimensional excitons in transition-metal dichalcogenides
Høgni C. Kamban, Thomas G. Pedersen
Generation of photocurrents in semiconducting materials requires dissociation of excitons into free charge carriers. While thermal agitation is sufficient to induce dissociation in…
Tuning of impurity-bound interlayer complexes in a van der Waals heterobilayer
Fabien Vialla, Mark Danovich, David A. Ruiz-Tijerina +10
Due to their unique two-dimensional nature, charge carriers in semiconducting transition metal dichalcogenides (TMDs) exhibit strong unscreened Coulomb interactions and sensitivity…
Nonlinear optical selection rules of excitons in monolayer transition metal dichalcogenides
Alireza Taghizadeh, T. G. Pedersen
We propose an analytical approach for calculating the linear and nonlinear optical (NLO) responses of monolayer transition metal dichalcogenides (TMDs) including excitonic effects.…
Iterative approach to arbitrary nonlinear optical response functions of graphene
F. Hipolito, Darko Dimitrovski, T. G. Pedersen
Two-dimensional materials constitute an exciting platform for nonlinear optics with large nonlinearities that are tunable by gating. Hence, gate-tunable harmonic generation and int…
