Controlling Intertwined Electronic Orders in FeSe with Exfoliation
Wenyao Liu, Gabriel Natale, Kyung-Mo Kim +14
Controlling intertwined electronic orders in two-dimensional superconductors offers an effective route to answering fundamental questions and engineering new quantum devices. Howev…
Pair density modulation from glide symmetry breaking and nematic superconductivity
Michał Papaj, Lingyuan Kong, Stevan Nadj-Perge +1
Pair density modulation is a superconducting state, recently observed in exfoliated iron-based superconductor flakes, in which the superconducting gap oscillates strongly with the…
Tunable superconducting diode effect in a topological nano-SQUID
Ella Nikodem, Jakob Schluck, Max Geier +6
A Josephson diode passes current with zero resistance in one direction but is resistive in the other direction. While such an effect has been observed in several platforms, a large…
Observation of Cooper-pair density modulation state
Lingyuan Kong, Michał Papaj, Hyunjin Kim +8
Superconducting states that break space-group symmetries of the underlying crystal can exhibit nontrivial spatial modulation of the order parameter. Previously, such remarkable sta…
Andreev reflection at the altermagnet-superconductor interface
Michał Papaj
Altermagnets are a new class of magnetic materials, which exhibit large spin splitting, but due to the combined spin and real space group symmetry protection maintain zero net macr…
Current-enabled optical conductivity of superconductors
Michał Papaj, Joel E. Moore
In most superconductors, optical excitations require impurity scattering or the presence of multiple bands. This is because in clean single-band superconductors, the combination of…
Tunable vortex Majorana zero modes in LiFeAs superconductor
Lingyuan Kong, Lu Cao, Shiyu Zhu +12
The recent realization of pristine Majorana zero modes (MZMs) in vortices of iron-based superconductors (FeSCs) provides a promising platform for long-sought-after fault-tolerant q…
Discovery of segmented Fermi surface induced by Cooper pair momentum
Zhen Zhu, Michał Papaj, Xiao-Ang Nie +12
Since the early days of Bardeen-Cooper-Schrieffer theory, it has been predicted that a sufficiently large supercurrent can close the energy gap in a superconductor and creates gapl…
A new Majorana platform in an Fe-As bilayer superconductor
Wenyao Liu, Lu Cao, Shiyu Zhu +16
Recently, iron-chalcogenide superconductors have emerged as a new and promising platform for studying and manipulating Majorana zero mode (MZM). By combining topological band struc…
Nearly quantized conductance plateau of vortex zero mode in an iron-based superconductor
Shiyu Zhu, Lingyuan Kong, Lu Cao +15
Majorana zero-modes (MZMs) are spatially-localized zero-energy fractional quasiparticles with non-Abelian braiding statistics that hold a great promise for topological quantum comp…
Observation of half-integer level shift of vortex bound states in an iron-based superconductor
Lingyuan Kong, Shiyu Zhu, Michał Papaj +14
Vortices in topological superconductors host Majorana zero modes (MZMs), which are proposed to be building blocks of fault-tolerant topological quantum computers. Recently, a new s…
