Research Interests
Fundamentally
new behavior has been documented in recent years in electronic systems
showing strong correlation and extreme confinement. The condensed
matter theory group led by Prof. Jankó is actively participating
in several major developments of this field, such as (i)
spin control, manipulation and transport (spintronics), (ii)
nanoscale superconductivity and magnetism in metallic and
semiconductor quantum dots and quantum wires, and (iii)
novel superconductivity (MgB2, high temperature superconductors)
and magnetism (diluted magnetic semiconductors). Our theory projects
within spintronics and nanoscience are performed parallel to and
in close collaboration with the experimental research effort of
our Nanoscale Interdisciplinary Research Team (NIRT). This team,
led by Professor Jankó, brings together researchers from
four institutions (Notre Dame, Argonne National Lab, University
of Illinois-Chicago and Duke University), with complementary expertise
in superconductivity, magnetism and semiconductor science and technology.
Within the NIRT project our research focuses on hybrid materials,
such as the submicron-patterned superconductor-diluted magnetic
semiconductor bi-layers. These structures are excellent candidates
for hosting spin polarized, Zeeman localized electronic states which
in turn could function as building blocks for spintronics applications.
Our research is supported by the National Science Foundation, Department
of Energy, and the Alfred P. Sloan Foundation.
