Nanoscience Research topics and Current fields of interest

Theoretical development of fundamental aspects and computational applications of many-body methods (at zero and finite temperature) to describing ground-state properties, electronic spectra, plasmon-like oscillations, decay, fragmentation, and fission, as well as the emergence of collective behavior and collective excitations in condensed-matter, finite-size systems and nanostructures; such as metal clusters, complex carbon clusters (e.g., fullerenes, and fullerene onions and coaxial nanotubes), helium-3 clusters, metallic nanowires and nanoconstrictions, two-dimensional semiconductor and graphene quantum dots, and rotating bosons in harmonic traps. This area of research is highly interdisciplinary and overlaps with several fields, such as condensed-matter physics, materials science, computational physics, mesoscopics, physical chemistry, inorganic and organic chemistry, quantum chemistry, few-body systems, the fractional quantum Hall effect, atomic and molecular physics, Bose-Einstein condensation, nuclear physics, astrophysics, and quantum computing.

Examples of strongly correlated behavior in artificial nanostructures




Unrestricted Hartree-Fock electron density in a parabolic quantum dot for the case of 19 electrons at zero magnetic field, exhibiting breaking of the circular symmetry and formation of a Wigner crystallite (or Wigner molecule). For details, see publication No. 67.





Conditional Probability Distributions for N=7 electrons at high magnetic fields (the electronic wave functions are restricted to the lowest Landau level). The example shown corresponds to magic angular momentum L=105 (nu=1/5). LEFT: the case of the rotating Wigner molecule (RWM); CENTER: the exact-diagonalization (EXD) case; RIGHT: the case of the Jastrow-Laughlin (JL) wave function. Unlike the RWM wave function, the JL wave function fails to capture the crystalline character of the EXD state. For details, see publications No. 71 and 68.

      The figure above (part of Fig. 12) was selected to be displayed on the front page of the PRB website (as part of the feature "Kaleidocope"). It portrays the tight-binding density at high magnetic field of an edge state (between Landau levels) in a hexagonal graphene flake with zigzag edge terminations.
