摘要：

We present an ab-initio molecular dynamics study of the modifications induced on fullerite by the irradiation with ultrashort very intense laser pulses. We identified the thresh:old for the non-thermal cage-opening of the C-60 molecules which is the analogue of the laser-induced non-thermal melting observed in semiconductors and graphite. The new phase formed by the non-thermal coalescence of the C-60 molecules is fluid-like and mainly formed by small chains of 2-fold coordinated carbon atoms.
