The NIKA instrument: results and perspectives towards a permanent KID based camera for the Pico Veleta observatory [PDF]

open access: yes, 2013
The New IRAM KIDs Array (NIKA) is a pathfinder instrument devoted to millimetric astronomy. In 2009 it was the first multiplexed KID camera on the sky; currently it is installed at the focal plane of the IRAM 30-meters telescope at Pico Veleta (Spain ...

Asymmetry of the Ferroelectric Phase Transition in BaTiO3

open access: yesAdvanced Materials, EarlyView.
Phase transitions are typically assumed to behave identically in forward and reverse. This work shows that in the ferroelectric material barium titanate this is not true: heating drives an abrupt, first‐order jump, while cooling gives a smooth, continuous change.

Anomalous Spin‐Optical Helical Effect in Ti‐Based Kagome Metal

open access: yesAdvanced Materials, EarlyView.
The kagome lattice hosts diverse correlated quantum states, including elusive loop currents. We report spin‐handedness selective signals in CsTi3Bi5, termed the anomalous spin‐optical helical effect, surpassing conventional spin responses. Arising from light helicity coupled to spin‐orbital correlations, this effect provides a sensitive, indirect probe

Current Switching of Topological Spin Chirality in the van der Waals Antiferromagnet Co1/3TaS2

open access: yesAdvanced Materials, EarlyView.
Spin chirality plays a central role in quantum magnetism, governing spin winding and generating real‐space Berry phases. We propose the intriguing concept of current‐switching spin chirality and demonstrate it via unconventional intrinsic self‐spin‐orbit‐torque in pristine Co1/3TaS2, purely by electrical current and with high energy efficiency.
