Materials Sciences and Engineering Research Highlights

Cuckoo-Inspired, Fast Model Design of High-Entropy Alloys

We accelerate computational design of high-entropy alloys with targeted disorder by ultrafast model generation using a metaheuristic Hybrid Cuckoo Search (CS).

Light induced Weyl semimetals with exceptional ballistic transport

Topological phase transitions may be controlled by a coherent light-induced phononic symmetry switch, without the application of static electric or magnetic fields.

Linking local structure order in metallic glass and competing crystalline phases

Short- and medium-range orders in Al90Tb10 glass are shown to be similar to structures of competing crystalline phases.

Critical role of electron correlations on exchange interactions and spin excitations

Including nonlocal electron correlations in electronic structure calculations yields spin excitations consistent with inelastic neutron-scattering measurements in CrI3.

High-Entropy Alloys Design and Origin of Properties

Vacancy-Mediated Order in Refractory High-Entropy Alloys

Optical detection and manipulation of spontaneous gyrotropic electronic order

Layered material TiSe2 spontaneously develops a gyrotropic electronic order at low temperatures. Left-handed and right-handed domains are formed.

Robust Metallized-DNA Meta-atoms

Demonstrated robust optical response of metallized-DNA self-assembled metamaterials having realistic disorder and surface roughness.

Topological Electronic Control by Quantum Periodic Motion

Imposing vibrational coherence into topological states may become a universal light control principle for reinforcing protected quantum transport.

Dark-state-based low-loss dual-response metasurfaces

Hybrid dark-state metasurfaces achieved separate implementation of resonance and electromagnetic response, enabling more versatile and configurable metamaterials.
