Bosonic phases across the superconductor-insulator transition in infinite-layer samarium nickelate
Menghan Liao, Heng Wang, Mingwei Yang +14
Superconductivity arises from the global phase coherence of Cooper pairs. Modulation of phase coherence leads to quantum phase transitions, serving as an important tool for studyin…
Reversible tuning of magnetic order and intrinsic superconductivity in strained FeTe films via stoichiometry control
Hao Xu, Jing Jiang, Xuesong Gai +11
FeTe is a prototypical parent compound of iron-based superconductors. While bulk FeTe is non-superconducting with a long-range bicollinear antiferromagnetic order, superconductivit…
Concurrent Ferromagnetism and Superconductivity in Fe(Te,Se) van der Waals Josephson Junctions
Gang Qiu, Hung-Yu Yang, Lunhui Hu +9
Ferromagnetism and superconductivity are two key ingredients to create non-Abelian quasiparticle excitations that are expected as building blocks to construct topological quantum c…
Edge states at nematic domain walls in FeSe films
Yonghao Yuan, Wei Li*, Bin Liu +9
Quantum spin Hall (QSH) effect is an intriguing phenomenon arising from the helical edge states in two-dimensional topological insulators. We use molecular beam epitaxy (MBE) to pr…
Electronically driven nematicity in FeSe Films on SrTiO3
W. Li, Y. Zhang, J. J. Lee +12
The intriguing role of nematicity in iron-based superconductors, defined as broken rotational symmetry below a characteristic temperature, is an intensely investigated contemporary…
Superconductivity in a single layer alkali-doped FeSe: a weakly coupled two-leg ladder system
Wei Li, Hao Ding, Pengfei Zhang +10
We prepare single layer potassium-doped iron selenide (110) film by molecular beam expitaxy. Such a single layer film can be viewed as a two-dimensional system composed of weakly c…
KFe_2Se_2 is the parent compound of K-doped iron selenide superconductors
Wei Li, Hao Ding, Zhi Li +9
We elucidate the existing controversies in the newly discovered K-doped iron selenide (KxFe2-ySe2-z) superconductors. The stoichiometric KFe2Se2 with \surd2\times\surd2 charge orde…
Phase Separation and Magnetic Order in K-doped Iron Selenide Superconductor
Wei Li, Hao Ding, Peng Deng +8
Alkali-doped iron selenide is the latest member of high Tc superconductor family, and its peculiar characters have immediately attracted extensive attention. We prepared high-quali…
