Controlling magnetism with polarized light: Non-thermal pathway uses inverse Faraday effect

Intense laser pulses can be used to manipulate or even switch the magnetization orientation of a material on extremely short time scales. Typically, such effects are thermally induced, as the absorbed laser energy heats up ...

Elusive temporary star described in historical documents recreated using new computer model

A mysterious remnant from a rare type of supernova recorded in 1181 has been explained for the first time. Two white dwarf stars collided, creating a temporary "guest star," now labeled supernova (SN) 1181, which was recorded ...

Novel method enhances size-controlled production of luminescent quantum dots

Luminescence refers to the result of a process in which an object absorbs light at one wavelength and then re-emits it at another wavelength. Through light absorption, electrons in the ground state of the material are excited ...
