# because we use a dictionary to store the graph and a list to store the state of each node. # The space complexity is dominated by the space used to store the graph and the state list.

Abstract: Topological photonic crystals, particularly valley photonic crystals, offer a robust platform for controlling light propagation. However, most existing topological devices possess fixed ...

If you want to solve a tricky problem, it often helps to get organized. You might, for example, break the problem into pieces and tackle the easiest pieces first. But this kind of sorting has a cost.

Topological materials are a class of materials that exhibit unique electronic properties at their boundary (surface in 3D materials; edge in 2D materials) that are robust against imperfections or ...

Two Columbia students, Roy Lee and Neel Shanmugam, dropped out of the University after facing disciplinary action for creating an artificial intelligence coding software that works undetected when ...
