摘要/Abstract

摘要：

Synthetic dimensions in time (Sambe space) can be utilized in a periodic time-dependent system. By subjecting the system into a time-periodic potential and measuring the physical quantities at distinct time in one period, one is able to simulate the models in higher dimension. To verify this approach, we show that the Bloch oscillation of wave packets along the magnetic field in a three-dimensional (3D) Weyl metal can be simulated on a two-dimensional (2D) insulator. Different from the chiral anomaly, this Bloch oscillation is anisotropic when the initial wave packet is not on the 0-th Landau level.
