Negative temperature states of bosons in triangular and kagome lattices

open access: yes
This thesis reports on experiments using ultracold bosonic ³⁹K atoms to study quantum many-body states in frustrated lattices. For the first time, we load the atoms into the optical triangular and kagome lattices at negative temperature, where most atoms occupy the states with the highest energy.

Electrically Tunable Room‐Temperature Microwave Oscillations in GaN/AlN Triple‐Barrier Resonant Tunneling Diodes

open access: yesAdvanced Electronic Materials, EarlyView.
III‐nitride semiconductors have revolutionized optoelectronics, enabling transformative technologies such as high‐efficiency LEDs and lasers. However, their use in intersubband optoelectronics has remained limited. This work marks an important step forward by demonstrating highly coherent inter‐well resonant tunneling injection in III‐nitride ...
