Universal thermal breakdown of polaron coherence in one, two, and three dimensions
Jeet Shannigrahi, Janez Bonča, Mona Berciu
How a polaron loses its quasiparticle coherence with increasing temperature is a long-standing open problem. Holstein addressed it in 1959 only in the extreme antiadiabatic, strong…

Supercontinuum Generation in 1-decanol
Nathan G. Drouillard, TJ Hammond
Although solids have been recently used in ultrafast experiments for spectral broadening due to their relatively high nonlinearity, their sensitivity to damage limits their long-te…

An exploration of the phonon frequency spectrum and Born-von Karman periodic boundary conditions in 1D and 2D Lattice systems using a computational approach
Jeet Shannigrahi, Pragati Ashdhir
The concept of periodic boundary conditions (PBCs) is immensely significant in treating an ideal lattice of infinite extent as a finite lattice. An explicit usage of PBCs is often…
