Data-driven equation for drug-membrane permeability across drugs and membranes
Arghya Dutta, Jilles Vreeken, Luca M. Ghiringhelli +1
Drug efficacy depends on its capacity to permeate across the cell membrane. We consider the prediction of passive drug-membrane permeability coefficients. Beyond the widely recogni…
Low Temperature Growth of Graphene on Semiconductor

The industrial realization of graphene has so far been limited by challenges related to the quality, reproducibility, and high process temperatures required to manufacture graphene…
Nuclear dynamics of singlet exciton fission: a direct observation in pentacene single crystals
Hélène Seiler, Marcin Krynski, Daniela Zahn +7
Singlet exciton fission (SEF) is a key process in the development of efficient opto-electronic devices. An aspect that is rarely probed directly, and yet has a tremendous impact on…
Enhanced THz emission from spintronic Fe/Pt emitters through crystal growth optimization
Agne Ciuciulkaite, Oliver Gueckstock, Anna Ravensburg +6
We investigate the THz emission characteristics of ferromagnetic/non-magnetic metallic heterostructures, focusing on thin Fe/Pt bilayers. In particular, we report on the impact of…
Exchange-striction driven ultrafast nonthermal lattice dynamics in NiO
Y. W. Windsor, D. Zahn, R. Kamrla +7
We use femtosecond electron diffraction to study ultrafast lattice dynamics in the highly correlated antiferromagnetic (AF) semiconductor NiO. Using the scattering vector (Q) depen…
Cold chemistry: a few-body perspective on impurity physics of a single ion in an ultracold bath
Jesús Pérez-Ríos
Impurity physics is a traditional topic in condensed matter physics that nowadays is being explored in the field of ultracold gases. Among the different classes of impurities, we f…
Nonequilibrium Charge-Density-Wave Order Beyond the Thermal Limit
J. Maklar, Y. W. Windsor, C. W. Nicholson +17
The interaction of many-body systems with intense light pulses may lead to novel emergent phenomena far from equilibrium. Recent discoveries, such as the optical enhancement of the…
Frequency-independent terahertz anomalous Hall effect in DyCo, CoFe and GdFe thin films from DC to 40 THz
Tom S. Seifert, Ulrike Martens, Florin Radu +11
The anomalous Hall effect (AHE) is a fundamental spintronic charge-to-charge-current conversion phenomenon and closely related to spin-to-charge-current conversion by the spin Hall…
All-electron periodic implementation with numerical atomic orbital basis functions: algorithm and benchmarks
Xinguo Ren, Florian Merz, Hong Jiang +5
We present an all-electron, periodic {\GnWn} implementation within the numerical atomic orbital (NAO) basis framework. A localized variant of the resolution-of-the-identity (RI) ap…

Zeptosecond Birth Time Delay in Molecular Photoionization
Sven Grundmann, Daniel Trabert, Kilian Fehre +11
Photoionization is one of the fundamental light-matter interaction processes in which the absorption of a photon launches the escape of an electron. The time scale of the process p…
Broadband terahertz probes of anisotropic magnetoresistance disentangle extrinsic and intrinsic contributions
Lukáš Nadvorník, Martin Borchert, Liane Brandt +10
Anisotropic magnetoresistance (AMR) is a ubiquitous and versatile probe of magnetic order in contemporary spintronics research. Its origins are usually ascribed to extrinsic effect…
