Quantized crystalline-electromagnetic responses in insulators
Sachin Vaidya, André Grossi Fonseca, Mark R. Hirsbrunner +2
We introduce new classes of gapped topological phases characterized by quantized crystalline-electromagnetic responses, termed "multipolar Chern insulators". These systems are char…
Prevalence of two-dimensional photonic topology
Ali Ghorashi, Sachin Vaidya, Mikael Rechtsman +3
The topological characteristics of photonic crystals have been the subject of intense research in recent years. Despite this, the basic question of whether photonic band topology i…
Quantum plasmons with optical-range frequencies in doped few-layer graphene
Sharmila N. Shirodkar, Marios Mattheakis, Paul Cazeaux +3
Although plasmon modes exist in doped graphene, the limited range of doping achieved by gating restricts the plasmon frequencies to a range that does not include visible and infrar…
Quantum corrections in nanoplasmonics: shape, scale, and material
Thomas Christensen, Wei Yan, Antti-Pekka Jauho +2
The classical treatment of plasmonics is insufficient at the nanometer-scale due to quantum mechanical surface phenomena. Here, an extension to the classical paradigm is reported w…
Unconventional plasmon-phonon coupling in graphene
M. Jablan, M. Soljačić, H. Buljan
We calculate hybridization of plasmons and intrinsic optical phonons in graphene by using the self-consistent linear response formalism. We find that longitudinal plasmons (transve…
