A Class of Long Range Circulant Random Walks on $Z_{q}^{d}$

Robert Griffiths, Shuhei Mano

This paper studies a class of long range random walks $(X_{t})_{t = 0}^{\infty}$ on the direct product of cyclic groups $Z_{q}^{d}$ for $d \geq 1$ and $q \geq 2$ . $X_{t+1} = X_t + Z_t \…

Symmetric Quantum Walks on Hamming Graphs and Their Limit Distributions

Robert Griffiths, Shuhei Mano

We study a class of symmetric coined quantum walks on Hamming graphs, where the distance between vertices specifies the transition probability. A special model is the simple quantu…

A Class of Gaussian Fields on $Z_{q}^{d}$

Robert Griffiths, Shuhei Mano

Gaussian fields $(g_{x})$ on $Z_{q}^{d}$ are constructed from a class of reversible long range random walks $(X_{t})_{t \in N}$ on $Z_{q}^{d}$ in arXiv:2510.22554. Th…

Gaussian Fields on a hypercube from Long Range Random Walks

Robert Griffiths

We consider a class of Gaussian Free Fields denoted by $(g_{x})_{x \in V_{N}}$ , where $V_{N} = {0, 1}^{N}$ and $N \in Z_{+}$ . These fields are related to a general cl…
