Experimental investigation of the load exerted by nonstationary internal solitary waves on a square column beneath an ice keel Open
The safety of marine structures and underwater vehicles is seriously threatened by the nonstationary internal solitary waves (ISWs) beneath an ice keel. Laboratory experiments were conducted in a stratified fluid flume to examine the load …

Perfect Coulomb drag and exciton transport in an excitonic insulator Open
Strongly coupled electron-hole bilayers can host quantum states of interlayer excitons, such as high-temperature exciton condensates at zero magnetic field. This state is predicted to feature perfect Coulomb drag, where a current in one la…
