Water: A tale of two liquids

…, H Tanaka, C Vega, L Xu, LGM Pettersson - Chemical …, 2016 - ACS Publications
Water is the most abundant liquid on earth and also the substance with the largest number
of anomalies in its properties. It is a prerequisite for life and as such a most important subject …

[HTML][HTML] The structural origin of anomalous properties of liquid water

A Nilsson, LGM Pettersson - Nature communications, 2015 - nature.com
Water is unique in its number of unusual, often called anomalous, properties. When hot it is
a normal simple liquid; however, close to ambient temperatures properties, such as the …

Chemical bonding on surfaces probed by X-ray emission spectroscopy and density functional theory

A Nilsson, LGM Pettersson - Surface Science Reports, 2004 - Elsevier
X-ray emission spectroscopy applied to surface adsorbates is an experimental technique
that provides an atom-specific projection of the electronic structure. In combination with …

Openai gym

G Brockman, V Cheung, L Pettersson… - arXiv preprint arXiv …, 2016 - arxiv.org
OpenAI Gym is a toolkit for reinforcement learning research. It includes a growing collection
of benchmark problems that expose a common interface, and a website where people can …

The structure of the first coordination shell in liquid water

…, TK Hirsch, L Ojamae, P Glatzel, LGM Pettersson… - Science, 2004 - science.org
X-ray absorption spectroscopy and x-ray Raman scattering were used to probe the
molecular arrangement in the first coordination shell of liquid water. The local structure is …

Modeling photocurrent action spectra of photovoltaic devices based on organic thin films

LAA Pettersson, LS Roman, O Inganäs - Journal of Applied Physics, 1999 - pubs.aip.org
We have modeled experimental short-circuit photocurrent action spectra of poly(3-(4 ′ -(1 ″
,4 ″ ,7 ″ -trioxaoctyl)phenyl)thiophene) (PEOPT)/fullerene ( C 60 ) thin film heterojunction …

Arctic climate change: observed and modelled temperature and sea-ice variability

…, VF Zakharov, LP Bobylev, LH Pettersson… - Tellus A: Dynamic …, 2004 - Taylor & Francis
Changes apparent in the arctic climate system in recent years require evaluation in a
century-scale perspective in order to assess the Arctic’s response to increasing anthropogenic …

Calculations of near-edge x-ray-absorption spectra of gas-phase and chemisorbed molecules by means of density-functional and transition-potential theory

L Triguero, LGM Pettersson, H Ågren - Physical Review B, 1998 - APS
We explore the utility of density-functional theory (DFT) in conjunction with the transition-potential
(TP) method to simulate x-ray-absorption spectra. Calculations on a set of small carbon…

The inhomogeneous structure of water at ambient conditions

…, S Shin, LGM Pettersson… - Proceedings of the …, 2009 - National Acad Sciences
Small-angle X-ray scattering (SAXS) is used to demonstrate the presence of density fluctuations
in ambient water on a physical length-scale of ≈1 nm; this is retained with decreasing …

Structure and bonding of water on Pt (111)

…, M Nyberg, A Pelmenschikov, LGM Pettersson… - Physical review …, 2002 - APS
We address the adsorption of water on Pt (111) using x-ray absorption, x-ray emission, and x-ray
photoelectron spectroscopy along with calculations in the framework of density …
