Superconductivity in metallic hydrogen
Dirk van der Marel, Christophe Berthod
Superconductivity, the lossless flow of electric current, occurs typically at very low temperatures. A possible exception is highly pressurized hydrogen, for which room temperature…

Brightened Optical Transition as Indicator of Multiferroicity in a Layered Antiferromagnet
Volodymyr Multian, Fan Wu, Dirk van der Marel +2
Two-dimensional van der Waals magnets show strong interconnection between their electrical, magnetic, and structural properties. Here we reveal the emergence of a luminescent trans…

Thermal and electrostatic tuning of surface phonon-polaritons in LaAlO3/SrTiO3 heterostructures
Yixi Zhou, Adrien Waelchli, Margherita Boselli +12
Phonon polaritons are promising for infrared applications due to a strong light-matter coupling and subwavelength energy confinement they offer. Yet, the spectral narrowness of the…
