Scientists use “quantum vacuum” to create a new kind of material
- Scientists at Rice University have developed a new way to control materials by reshaping the quantum vacuum around them.
- In quantum physics, the vacuum is full of virtual photons that can interact with materials.
- Researchers, led by Professor Junichiro Kono, created a 'chiral cavity' to manipulate quantum fluctuations using weak magnetic fields.
- The cavity was made from lightly doped indium antimonide combined with a photonic-crystal structure to enhance vacuum fluctuations.
- This design allows precise control over materials' properties without strong external forces, unlike previous methods.
- The cavity is capable of transforming graphene into a special insulator, crucial for quantum computing applications.
- Advanced simulations and a mix of classical and quantum theories were used to predict the behavior of materials inside the cavity.
- By tweaking the quantum vacuum, scientists can potentially engineer a variety of novel materials using this technology.
- The research opens up new possibilities for quantum devices and materials by utilizing the vacuum as an engineering tool.
