Two-dimensional Toda--Arnoldi correspondence: Holomorphic Krylov geometry and counterdiabatic transport
Urei Miura
Although Arnoldi reduction of a generally non-Hermitian Hamiltonian yields an upper Hessenberg matrix rather than the tridiagonal form of Hermitian Lanczos theory, we show that a c…
Exact steady states and fragmentation-induced relaxation in the no-passing asymmetric simple exclusion process
Urei Miura
We introduce a multispecies generalization of the asymmetric simple exclusion process with a "no-passing" constraint, forbidding overtaking, on a one-dimensional reflecting (closed…
Emergent spacetime supersymmetry in an interacting Kitaev chain with explicit supersymmetry
Urei Miura, Keisuke Totsuka
We investigate the emergence of spacetime supersymmetry (SUSY) in an interacting Kitaev chain model with explicit microscopic quantum mechanical SUSY. As the intera…
Interacting Kitaev Chain with Supersymmetry
Urei Miura, Kenji Shimomura, Keisuke Totsuka
Lattice models with supersymmetry are known to exhibit a variety of remarkable properties that do not exist in the relativistic models. In this paper, we introduce an interacting g…
Supersymmetry Breaking in a Generalized Nicolai Model with Fermion Pairing
Urei Miura, Keisuke Totsuka
We introduce a supersymmetric lattice fermion model that contains both fermion pairing and the interacting Nicolai model. This model possesses a single control parameter, , intr…
