Magnetically tunable symmetry-enforced nodal lines producing huge anomalous Hall conductivity in altermagnetic -MnTe
Mathews Benny, Xujia Gong, Amar Fakhredine +21
Altermagnetic -MnTe exhibits huge anomalous Hall conductivity (AHC) up to room-temperature together with weak ferromagnetism arising from spin and orbital polarizations. We clar…
Phonon-induced pseudogap phase in TiSe
Sotirios Fragkos, Nina Girotto Erhardt, Evgenia Symeonidou +9
To comprehend quantum ordered states, such as charge density waves (CDW), in layered transition metal dichalcogenides (TMDCs), it is essential to uncover their underlying normal st…
Electron-phonon-dominated charge-density-wave fluctuations in TiSe accessed by ultrafast nonequilibrium dynamics
Sotirios Fragkos, Hibiki Orio, Nina Girotto Erhardt +17
The complex phase diagram of 1T-TiSe2 consists of a charge density wave (CDW) below 200 K, and CDW fluctuations of still unknown origin at higher temperatures. Here, we use time-re…
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…
