In this work we propose a novel device for controlling the flow of information using Weyl fermions. Based on a previous work by our group, we show that it is possible to fully control the flow of Weyl fermions on several different channels by applying an electric field perpendicular to the direction of motion of the particles on each channel. In this way, we can transmit information as logical bits, depending on the existence or not of a Weyl current on each channel. We also show that the response time of this device is exceptionally low, less than 1 ps, for typical values of its parameters, allowing for the control of the flow of information at extremely high rates of the order of 100 Petabits per second. Alternatively, this device could also operate as an electric field sensor. In addition, we demonstrate that Weyl fermions can be efficiently guided through the proposed device using appropriate magnetic fields. Finally, we discuss some particularly interesting remarks regarding the electromagnetic interactions of high-energy particles.
在这项工作中，我们提出了一种利用外尔费米子控制信息流的新型器件。基于我们团队之前的一项工作，我们表明，通过在每个通道上施加一个垂直于粒子运动方向的电场，可以完全控制外尔费米子在几个不同通道上的流动。通过这种方式，我们可以根据每个通道上是否存在外尔电流，将信息作为逻辑比特进行传输。我们还表明，对于该器件参数的典型值，其响应时间极低，小于1皮秒，这使得能够以每秒100拍比特量级的极高速率控制信息流。另外，该器件也可以用作电场传感器。此外，我们证明了利用适当的磁场可以有效地引导外尔费米子通过所提出的器件。最后，我们讨论了一些关于高能粒子电磁相互作用的特别有趣的观点。
