Professor Margetis's research lies broadly in materials modeling and applied analysis, at the triple point of applied mathematics, theoretical physics, and materials science. The research topics are motivated by laboratory experiments and primarily explore the connection of continuumlike laws (e.g., PDEs for macroscopic variables) to discrete or microscopic models (e.g., ODE systems or microscopic Hamiltonian dynamics) in classical and quantum settings. Of particular interest are microscale effects that leave their signatures even at large scales.
Topics of current, active interest (with links to publications):
Morphological evolution of crystal surfaces below the roughening temperature;
freeboundary problems with microscale effects
Study of shape fluctuations of nanoparticles by use of analytical tools
Nonlocal macroscopic laws beyond the nonlinear Schrödinger (``GrossPitaevskii'') equation;
effects of atomic pair excitations
analysis of a class of firstkind Fredholm integral equations.
