Brownian Motion in Orthogonal and Symplectic Groups
Zhiyang Tan, Piet W. Brouwer
Matrix Brownian motion provides a powerful framework for studying crossover ensembles in quantum chaos and quantum transport, as well as thermalization and information scrambling i…

Operator spreading in random circuits with orthogonal or symplectic symmetry
Zhiyang Tan, Piet W. Brouwer
We investigate operator spreading in random quantum circuits with gates drawn from orthogonal-invariant or symplectic-invariant ensembles, revealing several key distinctions from t…
