Krylov complexity of fermion chain in double-scaled SYK and power spectrum perspective
Takanori Anegawa, Ryota Watanabe
We investigate Krylov complexity of the fermion chain operator which consists of multiple Majorana fermions in the double-scaled SYK (DSSYK) model with finite temperature. Using th…

The double scaling limit of randomly coupled Pauli XY spins
Ryota Watanabe
We consider the double scaling limit of a model of Pauli spin operators recently studied in Hanada et al. [1] and evaluate the moments of the Hamiltonian by the chord diagrams. We…
