  • The controlled manipulation of exotic quasiparticles known as anyons, a process known as “braiding,” is the basis of a powerful computational paradigm known as topological quantum computing. Substantial effort is currently being devoted to realizing such excitations in semiconductor heterostructures, but the milestone of braiding has yet to be achieved in such systems. ISU faculty member Thomas Iadecola is part of a research team that has recently demonstrated the possibility of braiding topological defects in photonic systems, whose properties mimic many of the salient features of their quantum counterparts.

  • Assistant Professor Peter P. Orth received the 2020 Cottrell Scholar Award from the Research Corporation for Science Advancement. The award provides a support of $100K for Orth's research into "Probing Fractionalization and Entanglement in Quantum Spin Liquids: Theory of Two-dimensional Spectroscopy". The award also recognize Orth's educational plan at Iowa State with the goal "to increase retention and recruitment of students from underrepresented groups in STEM fields by designing a transdisciplinary team-based learning course on quantum computing that is integrated with a learning community".

  • We are pleased to welcome Dr. Thomas Iadecola to the condensed matter physics group in our department.  He received his PhD from Boston University under the supervision of Prof. Claudio Chamon in 2017.  He has been a JQI Theoretical Postdoctoral Fellow at the University of Maryland, College Park from 2017 - 2019.  Tom works on a variety of topics in quantum condensed matter theory, with special emphasis on out-of-equilibrium quantum systems and topological states of matter. On the nonequilibrium side, he studies properties of highly-excited many-body states and the surprising phenomena they harbor that challenge deeply ingrained intuition based on quantum statistical mechanics.

  • Michael C. Tringides received the 2017 Theodore E. Madey Award from the American Vacuum Society for his excellence in internationally collaborative research.

    Tringides, a scientist at the U.S. Department of Energy’s (DOE) Ames Laboratory and a professor of physics and astronomy at Iowa State University explores how atoms move on surfaces. The process is essential in making nanotechnologies, such as computer transistors of much smaller size.

    According to Tringides, a computer’s speed depends on how far the electrons have to go across transistors. Current computer transistors may have hundreds of atoms along a linear dimension. Tringides hopes his work will be used to reduce that to only two or three.
