Magnetic field-induced momentum-dependent symmetry breaking in a kagome superconductor
Jianwei Huang, Zheng Ren, Hengxin Tan +17
When multiple degrees of freedom share similar energy scales in quantum materials, intertwined electronic orders, which exhibit broken symmetries, are often strongly coupled. Recen…
Probing the semiconductor-to-dirac semimetal transition in Na-Sb-Bi alloys with x-ray Compton scattering
Aki Pulkkinen, Veenavee Nipunika Kothalawala, Kosuke Suzuki +12
We discuss electron redistribution during the semiconductor-to-Dirac semimetal transition in Na-Sb-Bi alloys using x-ray Compton scattering experiments combined with first-principl…
Transition from Optically Excited to Intrinsic Spin Polarization in WSe
Sebastian Hedwig, Gregor Zinke, Jürgen Braun +6
Layered 2D van der Waals materials, such as transition metal dichalcogenides, are promising for nanoscale spintronic and optoelectronic applications. Harnessing their full potentia…
Reconstructing initial pressure and speed of sound distributions simultaneously in photoacoustic tomography
Miika Suhonen, Felix Lucka, Aki Pulkkinen +3
Image reconstruction in photoacoustic tomography relies on an accurate knowledge of the speed of sound in the target. However, the speed of sound distribution is not generally know…
Unveiling Fine Structure and Energy-driven Transition of Photoelectron Kikuchi Diffraction
Trung-Phuc Vo, Olena Tkach, Aki Pulkkinen +8
The intricate fine structure of Kikuchi diffraction plays a vital role in probing phase transformations and strain distributions in functional materials, particularly in electron m…
Revealing electronic correlations in YNiBC using photoemission spectroscopy
Aki Pulkkinen, Geoffroy Kremer, Vladimir N. Strocov +3
We present a combined density functional theory (DFT), one-step model of photoemission, and soft x-ray angle-resolved photoemission spectroscopy (SX-ARPES) study of the electronic…
Reexamining Circular Dichroism in Photoemission From a Topological Insulator
Ittai Sidilkover, Yun Yen, Sunil Wilfred D'Souza +10
The orbital angular momentum (OAM) of electron states is an essential ingredient for topological and quantum geometric quantities in solids. For example, Dirac surface states with…
Kramers nodal lines in intercalated TaS superconductors
Yichen Zhang, Yuxiang Gao, Aki Pulkkinen +24
Kramers degeneracy is one fundamental embodiment of the quantum mechanical nature of particles with half-integer spin under time reversal symmetry. Under the chiral and noncentrosy…
