Renata M. M. Wentzcovitch is a Professor of Materials Science and Engineering in the Applied Physics and Applied Mathematics Department, Earth and Environmental Sciences, and Lamont-Doherty Earth Observatory at Columbia University. Research in her group is devoted to computational quantum mechanical studies of materials. She addresses electronic, structural, and vibrational properties from a fundamental and inter-related perspective. She has developed and applied materials simulation methods particularly to investigate materials properties at high pressures and temperatures.
In 2013, Chris Marianetti was awarded a RISE grant entitled “A new approach to the interacting phonon problem”, which allowed for the support of a postdoctoral researcher and resulted in, among other things, a publication in a noted physics journal, Physical Review Letters. This work was substantial enough to form a foundation for a proposal to the Department of Energy (DOE) Basic Energy Sciences (BES) division, and this was recently (September 2016) funded at a level of $415,000 over a period of three years.
For nearly 60 years, scientists have been trying to determine how manganese oxide (MnO) achieves its long-range magnetic order of alternating up and down electron spins. Simon Billinge and Benjamin Frandsen used their recently developed mathematical approach to study the short-range magnetic interactions that they believe drive this long-range order. The research was described in a paper published on May 11 in Physical Review Letters. Photo credit: Columbia Engineering/Timothy Lee Photographers.
Irving Herman has been named the Edwin Howard Armstrong Professor of Applied Physics in the Fu Foundation School of Engineering and Applied Science. His appointment has been approved by the Trustees of Columbia University and he will be honored at the SEAS Faculty Excellence Celebration on September 20th, 2016.
High-performance energy storage devices will be key to a sustainable future, allowing cell phones to go longer between recharging, increasing mileage for electric vehicles, and stabilizing the power output of solar and wind energy. “Advanced batteries will be a game changer for addressing global challenges of energy sustainability and environmental stewardship,” says Yuan Yang, assistant professor of materials science and engineering. “Now is a really exciting time to work in batteries and energy storage.”
