Emergent Surface Kondo Flat Band Driven by Competing Interactions in a Topological Ferromagnet
Nazar Zaremba, Susmita Changdar, Haojie Guo +28
A central goal of modern condensed matter physics is to uncover new quantum states of matter arising from the intertwined effects of strong electron correlations, magnetism, and ba…
Probing bulk superconductivity in centrosymmetric Te-doped PtBi single crystals
Kilian Srowik, Pablo Pedrazzini, Soumen Ash +17
The Weyl semimetal -PtBi has been shown to be one of the most promising novel materials, recently proposed as a topological i-wave superconductor. A crucial requirement for…
Three prerequisites for high-temperature superconductivity in t-PtBi
Andrii Kuibarov, Susmita Changdar, Riccardo Vocaturo +9
Although the generic mechanism behind high-temperature superconductivity remains notoriously elusive, a set of favorable conditions for its occurrence in a given material has emerg…
Topological nodal -wave superconductivity in PtBi
Susmita Changdar, Oleksandr Suvorov, Andrii Kuibarov +11
Most superconducting materials are well-understood and conventional in the sense that the pairs of electrons that cause the superconductivity by their condensation have the highest…
Measuring superconducting arcs by ARPES
Andrii Kuibarov, Susmita Changdar, Alexander Fedorov +8
Angle-resolved photoemission spectroscopy is the leading tool for studying the symmetry and structure of the order parameter in superconductors. The recent improvement of the techn…
Electron dynamics in a three-dimensional Brillouin zone analysed by machine learning
Paulina Majchrzak, Charlotte Sanders, Yu Zhang +10
The electron dynamics in the unoccupied states of the Weyl semimetal PtBi is studied by time- and angle-resolved photoemission spectroscopy (TR-ARPES). The measurement's result…
Ultrafast carrier dynamics throughout the three-dimensional Brillouin zone of the Weyl semimetal PtBi
Paulina Majchrzak, Charlotte Sanders, Yu Zhang +10
Using time- and angle-resolved photoemission spectroscopy, we examine the unoccupied electronic structure and electron dynamics of the type-I Weyl semimetal PtBi. Using the abi…
Access to the full 3D Brillouin zone with time resolution, using a new tool for pump-probe ARPES
Paulina Majchrzak, Yu Zhang, Andrii Kuibarov +7
Here we report the first time- and angle-resolved photoemission spectroscopy (TR-ARPES) with the new Fermiologics "FeSuMa" analyzer. The new experimental setup has been commissione…
Superconducting Arcs
Andrii Kuibarov, Oleksandr Suvorov, Riccardo Vocaturo +12
An essential ingredient for the production of Majorana fermions that can be used for quantum computing is the presence of topological superconductivity. As bulk topological superco…
Crystal growth, characterization and electronic band structure of TiSeS
Y. Shemerliuk, A. Kuibarov, O. Feia +8
Layered semimetallic van der Waals materials TiSe2 has attracted a lot of attention because of interplay of a charge density wave (CDW) state and superconductivity. Its sister comp…
Suppression of nematicity by tensile strain in multilayer FeSe/SrTiO films
Rui Lou, Oleksandr Suvorov, Hans-Joachim Grafe +6
The nematicity in multilayer FeSe/SrTiO films has been previously suggested to be enhanced with decreasing film thickness. Motivated by this, there have been many discussions a…
Charge-Density-Wave-Induced Peak-Dip-Hump Structure and the Multiband Superconductivity in a Kagome Superconductor CsVSb
Rui Lou, Alexander Fedorov, Qiangwei Yin +7
The entanglement of charge density wave (CDW), superconductivity, and topologically nontrivial electronic structure has recently been discovered in the kagome metal VSb…
Fermi surface tomography
Sergey Borisenko, Alexander Fedorov, Andrii Kuibarov +19
Fermi surfaces, three-dimensional (3D) abstract interfaces that define the occupied energies of electrons in a solid, are important for characterizing and predicting the thermal, e…
