Warm dense matter, a unique regime where the behavior of materials is
significantly influenced by Fermi degenerate electrons, is the focus of recent
experimental investigations, shedding light on its unmagnetized
characteristics. However, the study of magnetized warm dense matter poses a
more intricate challenge. Existing techniques to create kilotesla order
magnetic fields in the lab involve dynamic field compression by compressing
pre-magnetized targets, but this method necessitates the use of multiple
high-power laser beams to ablate the target's outer surface. The resulting
high-density plasma impedes the penetration of the fast-heating laser beam
required for warm dense matter creation. Numerical simulations have revealed an
innovative alternative: magnetic field compression can be achieved by directing
laser beams onto the target's inner surface rather than the outer surface,
relying on a low-density, high-temperature plasma. This innovative approach
clears the region of the large magnetic field from excessive plasma, enabling
the compression beam to access the warm dense matter sample situated where the
magnetic field is the most intense.
