Building acoustic computers with tuneable phononic crystals
For more than two decades, physicists have been investigating wave propagation in phononic crystals, a metamaterial designed to control sound waves. A recent consideration involves using phononic crystals in acoustic computing. Acoustic computers execute basic Boolean algebra computations using acoustic waves. Dirac cones make this possible but achieving them is both very difficult and rare. Professor Sourav Banerjee and his […]

Molecular hopping in solid-like liquids: Understanding the self-diffusion and viscosity of liquid molecules
To fully understand how liquids flow, it is crucial for researchers to build models which can accurately recreate their behaviours on molecular scales – yet since the time of Newton, the complexities involved have presented numerous challenges. In their research, Prof Russ Keanini, Prof Peter Tkacik and Prof Jerry Dahlberg at the University of North Carolina, Charlotte, present new ways […]
