Why is it in the news?
The study demonstrated a device separating electrons by chirality without strong magnetic fields.
Marks progress towards low-power electronic devices.
Category: Science and Technology
Important Points:
● Chirality refers to left- or right-handed quantum state of electrons
● Observed in topological semimetals
● Earlier detection required strong magnetic fields or chemical doping
● Palladium gallium (PdGa) has twisted band structure
● Band structure causes sideways drift based on chirality
● Three-armed device separates left- and right-handed electrons
● Acts as chiral valve using quantum geometry
● Potential applications in low-power computing and magnetic memory devices
