Self-Assembled Periodic Nanostructures Using Martensitic Phase Transformations
Abhinav Prakash, Tianqi Wang, Ashley Bucsek +11
We describe a novel approach for the rational design and synthesis of self-assembled periodic nanostructures using martensitic phase transformations. We demonstrate this approach i…
Direct visualization of topological transitions and higher-order topological states in photonic metasurfaces
Anton Vakulenko, Svetlana Kiriushechkina, Mengyao Li +6
Topological photonic systems represent a new class of optical materials supporting boundary modes with unique properties, not found in conventional photonics. While the early resea…
Topological phases and nonreciprocal edge states in non-Hermitian Floquet Insulators
Mengyao Li, Xiang Ni, Matthew Weiner +2
Topological phases in quantum and classical systems have been of significant recent interest due to their fascinating physical properties. While a range of different mechanisms to…
Observation of Bulk Polarization Transitions and Higher-Order Embedded Topological Eigenstates for Sound
Xiang Ni, Matthew Weiner, Andrea Alù +1
Topological systems are inherently robust to disorder and continuous perturbations, resulting in dissipation-free edge transport of electrons in quantum solids, or reflectionless g…
Spin and valley polarized one-way Klein tunneling in photonic topological insulators
Xiang Ni, David Purtseladze, Daria A. Smirnova +3
Advances of condensed matter physics in exploiting the spin degree of freedom of electrons led to the emergence of the field of spintronics, which envisions new and more efficient…
Near-field imaging of spin-locked edge states in all-dielectric topological metasurfaces
A. Slobozhanyuk, A. V. Shchelokova, X. Ni +6
A new class of phenomena stemming from topological states of quantum matter has recently found a variety of analogies in classical systems. Spin-locking and one-way propagation hav…
