Squeezed Thermal Phonons Precurse Nonthermal Melting of Silicon as a Function of Fluence
A femtosecond-laser pulse can induce ultrafast nonthermal melting of various materials along pathways that are inaccessible under thermodynamic conditions, but it is not known whether there is any structural modification at fluences just below the melting threshold. Here, we show for silicon that in...
