Dynamics of an Exciton-phonon Triangle under Photoirradiation
Noriyuki Aoyagi, Hiroaki Matsueda, Kunio Ishida
Herein, the dynamics of excitons coupled with optical phonons in a triangular system is numerically studied. By representing the excitons by quasi-spin states, the similarity betwe…
Quantum Energy Teleportation and Entropy Change due to Feedback Control in One-Dimensional Heisenberg Model
Kanji Itoh, Yusuke Masaki, Hiroaki Matsueda
We study the quantum energy teleportation in a four-spin one-dimensional Heisenberg model. A local magnetic field is applied at the edge sites to control the degree of the ground-s…
Photoinduced pseudospin-wave emission from charge-density-wave domain wall with superconductivity
Yukihiro Matsubayashi, Yusuke Masaki, Hiroaki Matsueda
We study photoinduced dynamics triggered by an inhomogeneity due to competition between charge density waves (CDWs) and superconductivity. As a simple example, we consider the supe…
Derivation of Interacting Two-Qubit Dynamics from Spin-Boson Model
Hiroaki Matsueda, Yukiya Ide, Sadamichi Maekawa
We derive damping equations of motion for interacting two-spin states from a spin-boson model in order to examine qubit dynamics in quantum computers. On the basis of the composite…
Quasi-Particle Dynamics in Quasi-Periodic Ising Model with Temporally Fluctuating Transverse Fields
Kohei Ohgane, Yusuke Masaki, Hiroaki Matsueda
We study quasi-particle dynamics in a quasi-periodic Ising model with temporally fluctuating transverse fields. Specifically, we calculate the dynamical exponents of the standard d…
Entanglement distillation toward minimal bond cut surface in tensor networks
Takato Mori, Hidetaka Manabe, Hiroaki Matsueda
In tensor networks, a geometric operation of pushing a bond cut surface toward a minimal surface corresponds to entanglement distillation. Cutting bonds defines a reduced transitio…
