Two-dimensional boron (borophene) is a promising, newly synthesized monolayer metal
with promising electronic and optical properties. Borophene has only been recently …

This thesis provides a comprehensive introduction to two active research directions within
the field of plasmonics:(i) nonclassical, or quantum, aspects of the plasmonic response; and …

We predict the existence of long-lived and highly anisotropic plasmon modes in a two-
dimensional molybdenum oxide dichloride (MoO Cl 2) monolayer. We show that along the x …

A bstract Since holography yields exact results, even in situations where perturbation theory
is not applicable, it is an ideal framework for modeling strongly correlated systems. We …

We compute the dielectric properties of freestanding and metal-supported borophene from
first-principles time-dependent density functional theory. We find that both the low-and high …

Collective excitation of Dirac plasmons in graphene and topological insulators has opened
new possibilities of tunable plasmonic materials ranging from THz to mid-infrared regions …

We analyze collective excitations in models of two-dimensional topological insulators using
the random phase approximation. In a two-dimensional extension of the Su-Schrieffer …

Plasmon is a collective excitation in metals formed by the Coulomb interaction between
individual excitations of electron–hole pairs. In many previous studies on the plasmonic …

In bulk materials, the collective and individual modes are orthogonal to each other, and no
connection occurs in the absence of damping. In the presence of damping, the collective …

We study plasmonic excitations in the Kane-Mele model, a two-dimensional Z 2 topological
insulator on the honeycomb lattice, using the random phase approximation (RPA). In the …
