What does simplicial and non simplicial mean in the context of quantum mechanics?
What do they mean outside quantum mechanics and what makes you think they mean anything within quantum mechanics ?Jilang said:What does simplicial and non simplicial mean in the context of quantum mechanics?
It came up in this thread. The question arose in post #68dextercioby said:What do they mean outside quantum mechanics and what makes you think they mean anything within quantum mechanics ?
Thanks, but I am having some problems deciphering it. Is there a straightforward defininition?atyy said:

A simplicial complex is a mathematical structure used in topology to study geometric shapes. It is made up of simplices, which are geometric objects formed by joining vertices, edges, and higher dimensional elements.
In the context of quantum mechanics, a simplicial complex can represent the possible states of a quantum system. Each simplex in the complex corresponds to a different state, and the connections between simplices represent the transitions between states.
Using a simplicial complex can provide a more intuitive and visual representation of quantum systems, allowing for better understanding and analysis of their behavior. It also allows for the application of topological methods to study and solve quantum mechanical problems.
A simplicial complex can be constructed by assigning a set of basis states to the vertices of the complex and then connecting them based on the allowed transitions between states. The resulting structure is a representation of the quantum system's state space.
Yes, simplicial complexes have been used to analyze and solve various problems in quantum mechanics, such as determining the energy levels of a system or finding the shortest path between two states. They can also be applied to study entanglement and quantum information processing.
