The electronic structure of intertwined kagome, honeycomb, and triangular sublattices of the intermetallics MCoAl
Chiara Bigi, Sahar Pakdel, Michał J. Winiarski +10
Intermetallics are an important playground to stabilize a large variety of physical phenomena, arising from their complex crystal structure. The ease of their chemical tuneabilty m…
Exciton Superfluidity in 2D Heterostructures from First Principles: The importance of material specific screening
Rune Højlund, Emil Grovn, Sahar Pakdel +2
Recent theoretical and experimental studies suggest that van der Waals heterostructures with n- and p-doped bilayers of transition metal dichalcogenides are promising facilitators…
Excitonic insulators and superfluidity in 2D bilayers without external fields
Fredrik Nilsson, Mikael Kuisma, Sahar Pakdel +1
We explore a new platform for realising excitonic insulators, namely van der Waals (vdW) bilayers comprising 2D Janus materials. In previous studies, Type-II heterobilayers have be…
A group-theoretic approach to the origin of chirality-induced spin selectivity in non-magnetic molecular junctions
W. Dednam, M. A. García-Blázquez, Linda A. Zotti +4
Spin-orbit coupling gives rise to a range of spin-charge interconversion phenomena in non-magnetic systems where certain spatial symmetries are reduced or absent. Chirality-induced…
Few-layer antimonene electrical properties
Pablo Ares, Sahar Pakdel, Irene Palacio +10
Antimonene -- a single layer of antimony atoms -- and its few layer forms are among the latest additions to the 2D mono-elemental materials family. Numerous predictions and experim…
Visualizing band structure hybridization and superlattice effects in twisted MoS/WS heterobilayers
Alfred J. H. Jones, Ryan Muzzio, Sahar Pakdel +16
A mismatch of atomic registries between single-layer transition metal dichalcogenides (TMDs) in a two dimensional van der Waals heterostructure produces a moiré superlattice with a…
Ultrafast electronic line width broadening in the C 1s core level of graphene
Davide Curcio, Sahar Pakdel, Klara Volckaert +31
Core level binding energies and absorption edges are at the heart of many experimental techniques concerned with element-specific structure, electronic structure, chemical reactivi…
Electronic Properties of Single-Layer CoO/Au(111)
Ann Julie U. Holt, Sahar Pakdel, Jonathan Rodríguez-Fernández +11
We report direct measurements via angle-resolved photoemission spectroscopy (ARPES) of the electronic dispersion of single-layer CoO. The Fermi contour consists of a large hole…
Hot carrier-assisted switching of the electron-phonon interaction in 1-VSe
Paulina Majchrzak, Sahar Pakdel, Deepnarayan Biswas +20
We apply an intense infrared laser pulse in order to perturb the electronic and vibrational states in the three-dimensional charge density wave material 1-VSe. Ultrafast sna…
Moiré induced electronic structure modifications in monolayer VS on Au(111)
Umut Kamber, Sahar Pakdel, Raluca-Maria Stan +11
There is immense interest in how the local environment influences the electronic structure of materials at the single layer limit. We characterize moiré induced spatial variations…
Bypassing the computational bottleneck of quantum-embedding theories for strong electron correlations with machine learning
John Rogers, Tsung-Han Lee, Sahar Pakdel +5
A cardinal obstacle to performing quantum-mechanical simulations of strongly-correlated matter is that, with the theoretical tools presently available, sufficiently-accurate comput…
Room-temperature quantum spin Hall phase in laser-patterned few-layer 1T'- MoS2
Naoki Katsuragawa, Mizuki Nishizawa, Taketomo Nakamura +6
The quantum-spin-Hall (QSH) phase of 2D topological insulators has attracted increased attention since the onset of 2D materials research. While large bulk gaps with vanishing edge…
Observation of Electrically Tunable van Hove Singularities in Twisted Bilayer Graphene from nanoARPES
Alfred J. H. Jones, Ryan Muzzio, Paulina Majchrzak +16
The possibility of triggering correlated phenomena by placing a singularity of the density of states near the Fermi energy remains an intriguing avenue towards engineering the prop…
Exciton diffusion in two-dimensional metal-halide perovskites
Michael Seitz, Alvaro J. Magdaleno, Nerea Alcázar-Cano +7
Two-dimensional perovskites, in which inorganic layers are stabilized by organic spacer molecules, are attracting increasing attention as a more robust analogue to the conventional…
Surface-dominated Conductivity of Few-layered Antimonene
Sahar Pakdel, J. J. Palacios
We present a theoretical study of the phase-coherent DC conductivity of few-layered antimonene in the presence of surface disorder. It is well known that while a single layer is a…
Quenching of exciton recombination in strained two-dimensional monochalcogenides
J. J. Esteve-Paredes, Sahar Pakdel, J. J. Palacios
We predict that long-lived excitons with very large binding energies can also exist in a single or few layers of monochalcogenides such as GaSe. Our theoretical study shows that ex…
Strong Modulation of Optical Properties in Rippled 2D GaSe via Strain Engineering
David Maeso, Sahar Pakdel, Hernan Santos +4
Few-layer GaSe is one of the latest additions to the family of 2D semiconducting crystals whose properties under strain are still relatively unexplored. Here, we study rippled nano…
Faraday Rotation and Circular Dichroism Spectra of Gold and Silver Nanoparticle Aggregates
Sahar Pakdel, MirFaez Miri
We study the magneto-optical response of noble metal nanoparticle clusters. We consider the interaction between the light-induced dipoles of particles. In the presence of a magneti…
