Two-Parameter Ansatz for the Violation of Eigenstate Thermalization
Kohei Ohgane, Lev Vidmar
The eigenstate thermalization hypothesis (ETH) provides the prevailing framework for understanding quantum thermalization and ergodicity in isolated many-body systems. Yet, no gene…
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…
Quantum Singular Value Decomposition of Spin Correlation Matrix in One-Dimensional Heisenberg Model
Kohei Ohgane, Tatsuya Kumamoto, Hiroaki Matsueda
We present singular value decomposition of spin correlation matrix defined from the ground state of one-dimensional antiferromagnetic quantum Heisenberg model. The decomposition cr…
Voltage-Controlled Magnonic Spin Tunneling Junction
Kohei Ohgane, Yuta Yahagi, Daisuke Miura +1
We theoretically investigate the effective exchange interaction, , mediated by conductive electrons within a nonmagnetic metal spacer, in the presence of a bias vol…
