News from Attosecond Theory JRG

Mr. Dasol Kim Joined the Group

(Posted on 2013-9-25)

Mr. Dasol Kim, a graduate student at Physics Department, POSTECH, officially joined Attosecond Theory JRG from September 2013. He is co-supervised by Prof. Dong Eon Kim and Norio Takemoto. Dasol will work on theoretical research on ultrafast dynamics of atomic, molecular, and solid state systems. He had undergraduate research experience in Prof. Kim's group, and then he has been learning basic numerical methods for theoretical research in informal interaction with Norio. Welcome Dasol!

Organizing a Workshop in June 2013

(Posted on 2013-5-1)

Prof. Dong Eon Kim and Norio organize 'International Workshop on Attosecond Science: Challenges for Theoretical Research' at POSCO International Center on the campus of POSTECH on June 24 and 25, 2013. At this workshop, we would like to bring together active theorists and experimentalists to have intensive discussions on the following topics:

  1. theoretical approaches to understand and control the ultrafast electronic and nuclear dynamics in atoms and molecules;
  2. interesting experimental results which await formal understanding;
  3. newly emerging experimental techniques which may stimulate theoretical proposals of new schemes to investigate attosecond dynamics.

Norio Visits Prof. David Tannor

(Posted on 2013-4-1)

Norio is visiting Prof. David J. Tannor at Department of Chemical Physics, Weizmann Institute of Science in Israel. He stays with the Tannor group from March 30 to May 30, 2013 to work on the development of a multi-dimensional time-dependent Schroedinger equation solver based on a phase space approach.

Norio was David's postdoc from March 2011 to December 2012 and is excited to come back to the group again.

Visit of Prof. Ignacio Sola

(Posted on 2013-3-28)

Prof. Ignacio Sola at Universidad Complutense in Madrid, Spain, visits us on March 28, 2013. He will give a seminar as a guest speaker in the Ultrafast Science Journal Club organized by MPC-AS. Details about his talk are as following.

Place: Science Building No. 3, Room 201

Time: 12:15-14:15, March 28, 2013

Title: Creating and manipulating giant oscillating electric dipoles

Abstract: In this talk I propose different schemes that employ ultrafast (attosecond) pulses and static or low frequency fields in order to create and manipulate giant oscillating electric dipoles. The numerical results are obtained by solving the time-dependent Schrödinger equation in reduced dimensionality models with soft-core Coulomb potentials for the H2+ molecule. I show that to create and maintain the dipoles in addition to breaking the molecular symmetry it is necessary to force a correlated electronic and nuclear motion, thus pushing the period of oscillation of the dipoles from the natural electronic (attosecond) timescale to the nuclear (femtosecond) timescale.
