The dynamic response of Cerium under high pressure and temperature is not clear due to the complexity of its phase diagram. Using large-scale atomistic simulations, we report the γ→α phase transition (PT) of Ce under shock loading. The PT behavio

Frequency-domain interferometry is used to obtain the refractive index of compressed nitrogen in the vicinity of 1550 nm as the pressure of nitrogen increases from 0 to 40 MPa at room temperature. By referring to the equation of state of nitrogen, th

Resonant acceleration of electrons by a laser in the background of an extra longitudinal magnetic field is investigated analytically and numerically. The resonant condition is independent of laser intensity, and when satisfied, the energy gain is pro

Relativistic collisionless shock charged particle acceleration is considered as a possible origin of high-energy cosmic rays. However, it is hard to explore the nature of relativistic collisionless shock due to its low occurring frequency and remote

Electrons can be efficiently injected into a plasma wave by colliding two counterpropagating laser pulses in a laser wakefield acceleration. However, the generation of a high-quality electron beam with a large charge is difficult in the traditional o

Shock temperature of molybdenum is deduced to be 7853±813 K from release temperature at 374 GPa via pyrometry experiment. Theoretically, temperatures along the Hugoniot are calculated up to pressures of 500 GPa, over the shock melting pressure regio

We have performed the ab initio molecular dynamics (AIMD) simulations for aluminum in the density and temperature range of 2.35–7.00 g cm−3 and 1000–70 000 K, respectively. The equation-of-state data obtained from the AIMD simulations are consi

With a simple structure and control method, the piezo-inertia actuator is a preferred embodiment in the field of microprecision industry. However, most of the previously reported actuators are unable to achieve a high speed, high resolution, and low
