Electronically Amplified Electron-Phonon Interaction and Metal-Insulator Transition in Perovskite Nickelates
Yong Zhong, Kyuho Lee, Regan Bhatta +10
The relative role of electron-electron and electron-lattice interactions in driving the metal-insulator transition in perovskite nickelates opens a rare window into the non-trivial…

Highly confined epsilon-near-zero- and surface-phonon polaritons in SrTiO3 membranes
Ruijuan Xu, Iris Crassee, Hans A. Bechtel +13
Recent theoretical studies have suggested that transition metal perovskite oxide membranes can enable surface phonon polaritons in the infrared range with low loss and much stronge…
