Realization of broadband index-near-zero modes in nonreciprocal magneto-optical heterostructures
Yun Zhou, Panpan He, Sanshui Xiao +5
Epsilon-near-zero (ENZ) metamaterial with the relative permittivity approaching zero has been a hot research subject in the past decades. The wave in the ENZ region has infinite ph…
Topologically Protected Edge States in Triangular Lattices
Robert J. Davis, Yun Zhou, Dia'aaldin J. Bisharat +2
We describe the possibility for topologically robust edge states existing on interfaces of triangular lattices which are supported by rotational symmetries that are sensitive to bo…
On-chip unidirectional waveguiding for surface acoustic waves along a defect line in a triangular lattice
Yun Zhou, Naiqing Zhang, Dia'aaldin J. Bisharat +5
The latest advances in topological physics have yielded a rich toolset to design highly robust wave transfer systems, for overcoming issues like beam steering and lateral diffracti…
Photonic topological insulators a beginner's introduction
Dia'aaldin J. Bisharat, Robert J. Davis, Yun Zhou +2
Control and manipulation of electromagnetic waves has reached a new level with the recent understanding of topological states of matter. These metamaterials have the potential to r…
Confining and channeling sound through coupled resonators
Yun Zhou, Prabhakar R. Bandaru, Daniel F. Sievenpiper
Confining sound is of significant importance for the manipulation and routing acoustic waves. We propose a Helmholtz resonator (HR) based subwavelength sound channel formed at the…
Topological valley transport under long-range deformations
Zhixia Xu, Xianghong Kong, Robert J. Davis +4
Edge states protected by bulk topology of photonic crystals show robustness against short-range disorder, making robust information transfer possible. Here, topological photonic cr…
Spin-momentum locked modes on anti-phase boundaries in photonic crystals
Xianghong Kong, Yun Zhou, Gaobiao Xiao +1
An anti-phase boundary is formed by shifting a portion of photonic crystal lattice along the direction of periodicity. A spinning magnetic dipole is applied to excite edge modes on…
Energy Flux in Hierarchical Equations of Motion Method and Its Application to a Three-Level Heat Engine
Yun Zhou, Tie-Jun Xiao, Jun Cao +1
We derive the formula of energy flux for the hierarchical equations of motion (HEOM) method with the help of stochastic decoupling technique. The resulting expression is a combinat…
Topologically protected pseudospins in 2D spring-mass system
Yun Zhou, Prabhakar Bandaru, Daniel Sievenpiper
It is proposed that a lattice, with constituent masses and spring constants, may be considered as a model system for topological matter. For instance, a relative variation of the i…
Second order classical perturbation theory for atom surface scattering: analysis of asymmetry in the angular distribution
Eli Pollak, S. Miret-Artes
A second order classical perturbation theory is developed and applied to elastic atom corrugated surface scattering. The resulting theory accounts for experimentally observed asymm…
Minimal model of a heat engine: An information theory approach
Yun Zhou, Dvira Segal
We construct a generic model for a heat engine using information theory concepts, attributing irreversible energy dissipation to the information transmission channels. Using severa…
