P&A Colloquium: Giti Khodaparast, “Phononics and Magnonics in Materials with Strong Magneto-Electric Couplings”

Join the Department of Physics and Astronomy on Wednesday, March 5 at 2:30pm in White Hall G09 for a colloquium presented by Giti Khodaparast (Virginia Tech). The title of the talk is, “Phononics and Magnonics in Materials with Strong Magneto-Electric Couplings.” A reception will precede the colloquium at 2:00pm in White Hall 105/111.

Abstract

Magneto-electric phenomena in which a magnetic or electric polarization is induced via an external electric or magnetic field have attracted renewed research interest because of the possibility of creating novel electronic and optoelectronic devices. In this direction, multifunctional materials, with their enhanced coupling between electronic, vibrational, and spin degrees of freedom, are ushering in a new era of revolutionary advances in optoelectronics, spintronics, and quantum information and sensing. I will discuss how extensive multidisciplinary research is required to understand the inherent properties of complex systems such as multiferroics.

Biography

Professor Giti Khodaparast’s research activities at Virginia Tech have been focused on utilizing and enhancing the importance and power of magneto-optical spectroscopy to explore quantum coherence, correlations, and many-body effects in several materials systems that can play important roles in developing concepts for the next generation of devices or shed lights on the underlying interactions at the nanoscale. In addition, she has established strong national and international collaborations with large research facilities including the National High Magnetic Field Laboratory in Florida, and the Megagauss Laboratory in Kashiwa, Japan. She was selected as a fellow of OPTICA in 2024 and a fellow of SPIE in 2025.
