/4 phase shift in the angular magnetoresistance of infinite layer nickelates
Yoav Mairovich, Ariel Matzliach, Idan S. Wallerstein +4
The discovery of superconductivity in nickelates has generated significant interest in condensed matter physics. Nickelate superconductors, which are hole-doped within the layered…
Persistence of small polarons into the superconducting phase of BaKBiO
Muntaser Naamneh, Eugenio Paris, Daniel McNally +12
Bipolaronic superconductivity is an exotic pairing mechanism proposed for materials like BaKBiO (BKBO); however, conclusive experimental evidence for a (bi)polaron…
Observation of Flat Band and Van Hove Singularity in Non-superconducting Nitrogen-doped Lutetium Hydride
Xin Liang, Zihan Lin, Jun Zhang +15
Hydrogen-rich materials offer a compelling avenue towards room temperature superconductivity, albeit under ultra-high pressure. However, the experimental investigation of the elect…
Giant Chern number of a Weyl nodal surface without upper limit
Junzhang Ma, S. -N. Zhang, J. P. Song +15
Weyl nodes can be classified into zero-dimensional (0D) Weyl points (WPs), 1D Weyl nodal lines (WNL) and 2D Weyl nodal surfaces (WNS), which possess finite Chern numbers. Up to dat…
Metal to insulator transition at the surface of thin films: an in-situ view
Marco Caputo, Jasmin Jandke, Edoardo Cappelli +12
has long been studied as a prototypical strongly correlated material. The difficulty in obtaining clean, well ordered surfaces, however, hindered the use of surface sensit…
Surface state at evidenced by angle-resolved photoemission spectroscopy and ab initio calculations
Muntaser Naamneh, Abhinav Prakash, Eduardo B. Guedes +5
Perovskite alkaline earth stannates, such as and , showing light transparency and high electrical conductivity (when doped), have become promising candidates for…
Strain-engineering of the charge and spin-orbital interactions in Sr2IrO4
Eugenio Paris, Yi Tseng, Ekaterina M. Pärschke +16
In the high spin-orbit coupled Sr2IrO4, the high sensitivity of the ground state to the details of the local lattice structure shows a large potential for the manipulation of the f…
Multiple mobile excitons manifested as sidebands in quasi-one-dimensional metallic TaSe3
Junzhang Ma, Simin Nie, Xin Gui +22
Charge neutrality and their expected itinerant nature makes excitons potential transmitters of information. However, exciton mobility remains inaccessible to traditional optical ex…
Topological Magnetic Phase in the Candidate Weyl Semimetal CeAlGe
P. Puphal, V. Pomjakushin, N. Kanazawa +9
We report the discovery of topological magnetism in the candidate magnetic Weyl semimetal CeAlGe. Using neutron scattering we find this system to host several incommensurate, squar…
Strong- to weak-coupling superconductivity in high- bismuthates: revisiting the phase diagram via SR
T. Shang, D. J. Gawryluk, M. Naamneh +6
Several decades after the discovery of superconductivity in bismuthates, the strength of their electron-phonon coupling and its evolution with doping remain puzzling. To clarify th…
Electronic Localization in CaVO3 Films via Bandwidth Control
Daniel E. McNally, Xingye Lu, Jonathan Pelliciari +11
Understanding and controlling the electronic structure of thin layers of quantum materials is a crucial first step towards designing heterostructures where new phases and phenomena…
Spin fluctuation induced Weyl semimetal state in the paramagnetic phase of EuCdAs
J. -Z. Ma, S. M. Nie, C. J. Yi +22
Weyl fermions as emergent quasiparticles can arise in Weyl semimetals (WSMs) in which the energy bands are nondegenerate, resulting from inversion or time-reversal symmetry breakin…
Cooling a polaronic liquid: Phase mixture and pseudogap-like spectra in superconducting
M. Naamneh, M. Yao, J. Jandke +17
Many complex electronic systems exhibit so-called pseudogaps, which are poorly-understood suppression of low-energy spectral intensity in the absence of an obvious gap-inducing sym…
The electronic structure of BSCCO in the presence of a super-current: Flux-flow, Doppler shift and quasiparticle pockets
