The Half-Filled Landau Level: The Case for Dirac Composite Fermions

  • By Aude Marjolin
  • 13 April 2016

"All is well with particle-hole symmetry". Roger Mong and colleagues accross the United States provided strong evidence for a recent conjecture that contrasts with the predictions of standard theory and predicts a liquid consisting of massless Dirac particles that respects the symmetry between particles and holes

In an external magnetic field, the energy of an electron in a two-dimensional system takes discrete values, called Landau levels. At high enough fields, all electrons in a solid can fit in the lowest Landau level. If exactly half of that level is filled with electrons, standard theory predicts that a special fermion liquid phase will form that makes a distinction between the filled and empty states (particles and holes). However, a recent conjecture, in contrast, predicted a liquid consisting of massless Dirac particles that respects the symmetry between particles and holes, for which the authors of this paper provided strong evidence.

“The computers of the future may be born in Sara Majetich’s labs” reads the header of a recent news article.

For the past three years, Majetich has been a principal investigator for the Center for Spintronic Materials, Interfaces, and Novel Architectures (C-SPIN), which coordinates the research of 32 professors from 18 universities towards overcoming the limits of traditional computer design with spintronic technology.

Congratulations to the newest Distinguished Professor of Mechanical Engineering and PQI Professor Peyman Givi!

PQI Professor Peyman Givi received his award from the Provost Patricia Beeson during his inaugural lecture entitled "Exascale HPC, Big Data, and Quantum Computing in Rocket Science". This distinction was awarded to Peyman for his visionary mind, his outstanding research, as well as his incredible mentorship.


Giant Conductivity Switching of LaAlO3/SrTiO3 Heterointerfaces Governed by Surface Protonation

  • By Aude Marjolin
  • 22 February 2016

In their latest article, Jeremy Levy and his group put forward compelling experimental evidence of the role of surface chemistry on conductivity in complex oxides heterostructures. 

This work, published in Nature Communications on February 10, 2016 illustrates how the conductivity of the 2DEG layer in LAO/STO can be modulated using solvent immersion and illumination. 


Reflections on Nano and Femto Imaging

  • By Aude Marjolin
  • 12 February 2016

"Scanning near-field optical microscopy combined with pump–probe spectroscopy can resolve ultrafast dynamics at the nanoscale."

In this short article, Hrvoje Petek reflects on a new technique that combines the nanometre resolution of near-field microscopy with the femtosecond resolution of pump–probe spectroscopy. This technique has been developed by Markus Raschke and colleagues at the University of Colorado at Boulder and submitted in the present issue of Nature Nanotechnology.
