The team led by Prof. Alexander Balandin has made an important step toward the development of practical magnonic devices by studying, for the first time, the level of noise associated with the propagation of magnon current. The paper, “The discrete noise of magnons,” is a feature story in Applied Physics Letters, and will also appear...

Eavesdropping on wireless communications depends on the ability to determine critical information about the basic properties of the communication link, known as channel state information, or CSI. A new study suggests ways to prevent eavesdroppers from obtaining the channel state information, offering a first line of defense for wireless security. Yingbo Hua describes a scenario...
