it is possible to construct the x cube
it is possible to construct the x cube model by taking three stacks of toric code sheets, on along each of the three axes, superimposing them, and adding couplings to the edges where they intersect. this construction explains some of the connections that can be seen between the toric code topological order and the x cu...

it is possible to remotely detect the presence
it is possible to remotely detect the presence of an isolated elementary excitation in a region by moving the opposite type of elementary excitation around it. here, as usual, "moving" refers to the repeated action of local unitary operators that translate the particles. this process is known as interferometry. it can ...

an x, y {\displaystyle x,y} and z {\displaystyle z} lineon can all fuse into the vacuum, if the lines on which each of them move concur. that is, there is a sequence of local operators that can make this fusion happen. the opposite process can also happen. for a similar reason, an isolated lineon can change direction o...

this construction shows that an isolated fracton cannot be mobile in any direction. in other words, there is no local operator that can be acted on an isolated fracton to move it to a different location. in order to move an individual isolated fracton, one would need to apply a highly nonlocal operator to move the enti...
