Have you ever noticed a pattern in your carpet or tiles that creates a larger, intricate design? That’s called a Moire pattern, and it’s created when two periodic lattices lie on top of each other with a relative twist or a mismatched lattice constant. In the world of physics, this pattern can emerge in a fascinating way when stacking 2D materials like graphene, hexagonal boron nitride (hBN), molybdenum disulfide, and many others. By doing so, we can create a Moire superlattice, which is essentially a larger lattice that forms as a result of the interference between the two smaller lattices.
Quantum information dynamics is an emerging field that connects several topics, including non-equilibrium and driven quantum systems, many-body localization and thermalization, quantum chaos and black holes, and tensor network holography. Traditionally, physics has focused on the dynamics of matter and spacetime. However, considering the dynamics of quantum information is a new trend that deepens our understanding of the dynamics of matter and spacetime.
The holographic duality, also known as AdS/CFT, was originally proposed as a correspondence between a \((d+1)\)-dimensional quantum field theory and a \((d+1)\)-dimensional quantum gravity theory. The holographic duality is named as such because it encodes information about the space-time geometry in the higher-dimensional holographic bulk into the quantum many-body dynamics on the lower-dimensional holographic boundary.
