Artemis lab’s upgraded capabilities unlock real-time visualization of quantum material behavior

The recent publication from the upgraded Artemis lab space at the Science and Technology Facilities Council (STFC) Central Laser Facility (CLF) marks a significant milestone for the facility. By utilizing short light pulses from the 1 kHz beamline, researchers at Artemis were able to delve into the intricate world of tantalum diselenide (1T-TaSe2), a quantum material. This groundbreaking study enabled the visualization of electron and ion motion within materials in , unveiling valuable insights into their complex behaviors.

The research findings emphasize the crucial role played by crystal lattices in driving and stabilizing phase transitions in quantum materials. By comprehending these mechanisms, scientists can potentially engineer materials with exceptional electronic properties. This achievement was made possible due to the advanced capabilities of the state-of-the-art Artemis lab space, situated at the STFC Harwell Campus in Oxfordshire as part of the Research Complex at Harwell (RCaH). Artemis, inaugurated in late 2021, specializes in investigating the ultrafast motion of electrons in and novel materials. Its contributions have been particularly valuable in unraveling the behavior of charge-density-wave (CDW) transitions in quantum materials.

physics has witnessed intense research efforts dedicated to comprehending quantum materials, which exhibit extraordinary characteristics. The STFC Artemis lab space plays a pivotal role in unraveling the fundamental interactions that occur within these materials. Equipped with cutting-edge technologies such as ultrafast laser sources, XUV beamlines, and end-stations tailored for molecular dynamics, condensed matter physics, and imaging, the facility stands among the select few in the world capable of capturing and recording processes that transpire at femtosecond timescales.
