Grassmann numbers are mathematical objects that extend the concept of real and complex numbers. They have unique properties, such as anti-commutativity, which means that changing the order of multiplication changes the sign of the result. Grassmann numbers are used in physics, particularly in the field of quantum mechanics, to describe fermions, which are particles with half-integer spin. They are also used in differential geometry and algebraic topology to study geometric objects and symmetries.
Photonic molecules are structures made of multiple optical resonators that can manipulate light in unique ways. They have properties such as enhanced light-matter interactions and tunable optical properties. These molecules have applications in areas such as sensing, communication, and quantum information processing.
Microwave absorbing materials have properties that allow them to absorb and dissipate electromagnetic energy from microwaves. These materials are used in various applications such as stealth technology, radar absorption, and electromagnetic interference shielding.
Microwave absorption materials have properties that allow them to absorb and dissipate electromagnetic energy at microwave frequencies. These materials are used in various applications such as radar absorbing coatings, stealth technology, and electromagnetic interference shielding.
A hyperbolic lens has a unique shape that can focus light in a specific way, allowing for applications in fields such as astronomy, microscopy, and telecommunications. Its properties include the ability to correct spherical aberrations and produce high-resolution images.
Anti de Sitter space is a concept in theoretical physics that has key properties such as negative curvature and a boundary at infinity. It is used in various applications, including the study of holography and string theory.
