[Aspuru-Guzik group list] [qip] Friday 3pm talk at Harvard on Hamiltonian simulation by Dominic Berry

by aram harrow

Time: Friday, June 6, 3:00 PM Place: Cabot Division Room (Mallinckrodt Room 102), Harvard University Speaker: Dominic Berry ( http://www.dominicberry.org/ ) Title: Exponential improvement in precision for simulating sparse Hamiltonians Abstract: We provide a quantum method for simulating Hamiltonian evolution with complexity polynomial in the logarithm of the inverse error. This is an exponential improvement over existing methods for Hamiltonian simulation. In addition, its scaling with respect to time is close to linear, and its scaling with respect to the time derivative of the Hamiltonian is logarithmic. These scalings improve upon most existing methods. Our method is to use a compressed Lie-Trotter formula, based on recent ideas for efficient discrete-time simulations of continuous-time quantum query algorithms. _______________________________________________ qip mailing list qip(a)mit.edu http://mailman.mit.edu/mailman/listinfo/qip

[Aspuru-Guzik group list] Prof Joao Aires de Sousa

by Edward Pyzer-Knapp

Hi all Prof Joao Aires de Sousa will be visiting the group on 3rd and 4th June. He is an expert in cheminformatics and machine learning, and will be giving a short talk on his work predicting DFT-calculated properties (BDE, orbitals and charges) in the Div room at 10:45. If you would like to have a chat with him, please send me an email and I will see what I can sort out! Thanks Ed

[Aspuru-Guzik group list] Fwd: [ PSI-K ] Electronic structure software engineer and web developer, University of Oxford

by Alan Aspuru-Guzik

Dear all, The competition never sleeps. Alan ---------- Forwarded message ---------- From: *PSI-K* <psik-coord(a)dl.ac.uk> Date: Monday, June 2, 2014 Subject: [ PSI-K ] Electronic structure software engineer and web developer, University of Oxford To: PSI-K <psik-coord(a)dl.ac.uk> An announcement has been updated in the "PSI-K" site at PSI-K ( http://cselnx9.dl.ac.uk:8080/portal) Subject: Electronic structure software engineer and web developer, University of Oxford Category: Job From: Feliciano Giustino Date: 02-Jun-2014 09:00 Message: A senior postdoctoral position is available within the group of Prof. Feliciano Giustino in the Department of Materials at the University of Oxford (*http://giustino.materials.ox.ac.uk <http://giustino.materials.ox.ac.uk/index.php>*), to work on the development of electronic structure software and a web platform for materials informatics. The position is for four years starting on 1 October 2014. This position is part of a large project on computational design of novel materials for solar energy harvesting, which is funded by the Leverhulme Trust and is led by Prof. Giustino. The overarching goal of this project is to understand the atomic-scale mechanisms underpinning the light-induced generation and transport of charge carriers in novel materials for photovoltaics and artificial photosynthesis. Within this project we are seeking for a specialist in the development of electronic structure software and websites. The successful candidate will be responsible for the maintenance and development of electronic structure software, such as EPW (*http://epw.org.uk <http://epw.org.uk/>*, currently developed under subversion within the QE-Forge portal, http://qe-forge.org) and SternheimerGW [yet to be released, see Phys. Rev. B 88, 075117 (2013) and Phys. Rev. B 89, 085129 (2014)]. In addition he/she will be responsible for designing and implementing an online platform for materials informatics. This platform will serve the purpose of organizing and sharing data on electronic structure calculations for solar energy materials. The candidate is expected to hold a PhD in Physics, Chemistry, or Materials Science, and possess a strong background in methods and software for first-principles electronic structure calculations and web development. The successful candidate will join the Oxford Materials Modelling Laboratory, a thriving community of over 20 researchers at the centre of one of the leading universities in the world. High-performance computing resources will be available through the Materials Modelling Laboratory and the Oxford Supercomputing Centre. The closing date for applications is 12.00 midday on Thursday 10 July 2014 with Skype interviews currently planned for 29 July 2014. Applications for this post are to be made online at www.recruit.ox.ac.uk (vacancy reference 113529).
