Research led by scientists at the Okinawa Institute of Science and Technology (OIST) and Stanford University has demonstrated a new approach to Floquet engineering using excitons rather than photons. Floquet engineering is a field of physics in which scientists attempt to design new materials by shining light on them.
This approach in modern science might sound like attempts at alchemy, and on the face of it, Floquet engineering is attempting alchemy, but it aims to modify the material’s quantum states.
To explain this, scientists often cite examples of a pendulum or a swing. In both these cases, the repeated external force, also known as a periodic drive, lifts the pendulum or swing to greater heights even though the object is only oscillating back and forth.
Using this principle, scientists aim to imbue exotic quantum properties into ordinary materials.
