Long distance entanglement in one-dimensional quantum systems under sinusoidal deformation
Toshiya Hikihara, Takafumi Suzuki
We investigate entanglement generation in one-dimensional quantum spin systems with the sinusoidal deformation. In the system, the energy scale of each local term in the Hamiltonia…
