Nonlinearity in the heart Nonlinear wave dynamics can help to explain what happens to the heart during an irregularity of the heartbeat known as a cardiac arrhythmia. Computer models of the process are helping to improve methods for treating this potentially lethal medical condition. Your ...
Solitons underpin new laser Ackemann and colleagues Physicists in the UK and Germany have harnessed the curious properties of soliton waves to create a new type of semiconductor laser that can be switched on and off using light pulses. The team believe that this cavity solit ...
