Dichotomy in Low- and High-energy Band Renormalizations in Trilayer Nickelate La4Ni3O10: a Comparison with Cuprates
Band renormalizations comprise crucial insights for understanding the intricate roles of electron-boson coupling and electron correlation in emergent phenomena such as superconductivity. In this study, by combining high-resolution angle-resolved photoemission spectroscopy and theoretical calculations, we systematically investigate the electronic structure of the trilayer nickelate superconductor La4Ni3O10 at ambient pressure. We reveal a dichotomy in the electronic band renormalizations of Bi2Sr2CaCu2O8+δ in comparison to cuprate superconductors.

Material Innovation Platform Installed at Pusan National University
A newly installed Material Innovation Platform (MIP) at Pusan National University will support groundbreaking studies of strongly correlated electron phases in air-sensitive low-dimensional systems. Read how Prof. Choongyu Hwang and his team are already generating results only weeks after installation.
Sample Manipulators
Open and Closed Cycle Sample Manipulators
When aiming at high experimental energy resolution for ARPES measurement, it is crucial to achieve ultra-low sample temperatures to quench thermal broadening. This is possible with state-of-the-art cryo manipulators reaching sample temperatures from < 3.5 K and featuring up to 6 fully motorized axes for a large range of movements. The manipulators are available as open and closed cycle. Open cycle manipulators reach lower temperature specifications and are rapidly cooled down from room temperature to 10 K in 15 min. The low He consumption below 1 l/h at ultimate temperature and the possibility to operate with liquid nitrogen at higher temperatures ensure a low operating cost. Closed cycle manipulators have no He consumption providing unlimited holding time.
Service Upgrade
PEAK Slit Control
Optimal analyser settings with remote control
In photoelectron spectroscopy measurements, there is always a trade-off between signal intensity and resolution. Optimising this balance is the key to obtaining smooth and sharp spectra within the shortest time possible. For hemispherical analysers, this trade-off is controlled by the selected entrance slit and pass energy.
PEAK Slit Control replaces manual slit changes at the analyser with a motorised and software-controlled slit. With the control of all analyser settings, easy and quick optimisation of signal intensity versus resolution is possible.
