Chiral plasmons without magnetic field.
Plasmons, the collective oscillations of interacting electrons, possess emergent properties that dramatically alter the optical response of metals. We predict the existence of a new class of plasmons-chiral Berry plasmons (CBPs)-for a wide range of 2D metallic systems including gapped Dirac materials. As we show, in these materials the interplay between Berry curvature and electron-electron int...
متن کاملConsistent Chiral Kinetic Theory in Weyl Materials: Chiral Magnetic Plasmons.
We argue that the correct definition of the electric current in the chiral kinetic theory for Weyl materials should include the Chern-Simons contribution that makes the theory consistent with the local conservation of the electric charge in electromagnetic and strain-induced pseudoelectromagnetic fields. By making use of such a kinetic theory, we study the plasma frequencies of collective modes...
متن کاملPlasmons in nanoscale and atomic-scale systems.
Plasmons in metallic nanomaterials exhibit very strong size and shape effects, and thus have recently gained considerable attention in nanotechnology, information technology, and life science. In this review, we overview the fundamental properties of plasmons in materials with various dimensionalities and discuss the optical functional properties of localized plasmon polaritons in nanometer-sca...
متن کاملA chiral pentadecanuclear metallamacrocycle with a sextuple twisted Möbius topology.
Construction of cyclic molecules has received much attention in recent years because of both scientific curiosity and their potential use in applications such as magnetic materials, sensors for small molecules, and new classes of catalysts.1 Although the possibility of forming molecules with a twisted cyclic band structure (Möbius molecules) was predicted theoretically among organic molecules s...
متن کاملThe twisted arc model for chiral molecules
We present a simple model for chiral molecules which yields the frequency-dependent multipole-multipole polarizabilities required for calculating the dispersive van der Waals constants in a simple, closed, and consistent form. The model consists of a single effective charge confined to a one-dimensional wire formed by two circular arcs, which are twisted with respect to each other by an angle c...
