Dissipative free fermions in disguise
Kohei Fukai, Hironobu Yoshida, Hosho Katsura
Recently, a class of spin chains known as ``free fermions in disguise'' (FFD) has been discovered, which possess hidden free-fermion spectra even though they are not solvable via t…
Theory of Steady States for Lindblad Equations beyond Time-Independence: Classification, Uniqueness and Symmetry
Hironobu Yoshida, Ryusuke Hamazaki
We present a rigorous and comprehensive classification of the asymptotic behavior of time-dependent Gorini-Kossakowski-Sudarshan-Lindblad (GKSL) equations under the assumption of H…
Open quantum spin chains with non-reciprocity: a theoretical approach based on the time-dependent generalized Gibbs ensemble
Alice Marché, Hironobu Yoshida, Alberto Nardin +2
We study an open quantum spin chain with non-reciprocal dissipation using a theoretical approach known as time-dependent generalized Gibbs ensemble. In the regime of weak dissipati…
Asymptotically optimal unitary estimation in by the analysis of graph Laplacian
Satoshi Yoshida, Hironobu Yoshida, Mio Murao
Unitary estimation is the task to estimate an unknown unitary operator with queries to the corresponding unitary operation, and its accuracy is evaluated b…
Edge-Edge Correlations without Edge-States: -clustering State as Ground State of the Extended Attractive SU(3) Hubbard Chain
Hironobu Yoshida, Niclas Heinsdorf, Hosho Katsura
We explore the phase diagram of the extended attractive SU() Hubbard chain with two-body hopping and nearest-neighbor attraction at half-filling. In the large on-site attraction…
Rigorous results on the ground state of the attractive SU() Hubbard model
Hironobu Yoshida, Hosho Katsura
We study the attractive SU() Hubbard model with particle-hole symmetry. The model is defined on a bipartite lattice with the number of sites in the subla…
