Imaging superconducting weak spots through vortex-assisted THz near-field photovoltage
Sergio J. Salvía-Fernández, Ekaterina Khestanova, Zoe Velluire-Pellat +9
Nanoscale inhomogeneities are a defining feature of many superconducting materials, yet their local electromagnetic response has remained difficult to access experimentally. This i…
Terahertz photocurrent probe of quantum geometry and interactions in magic-angle twisted bilayer graphene
Roshan Krishna Kumar, Geng Li, Riccardo Bertini +24
Moiré materials represent strongly interacting electron systems bridging topological and correlated physics. Despite significant advances, decoding wavefunction properties underlyi…
Cryo-Near-Field Photovoltage Microscopy of Heavy-Fermion Twisted Symmetric Trilayer Graphene
Sergi Batlle-Porro, Dumitru Calugaru, Haoyu Hu +7
Ever since the initial experimental observation of correlated insulators and superconductivity in the flat Dirac bands of magic angle twisted bilayer graphene, a search for the mic…
All-optical seeding of a light-induced phase transition with correlated disorder
Allan S. Johnson, Ernest Pastor, Sergi Batlle-Porro +8
Ultrafast manipulation of vibrational coherence is an emergent route to control the structure of solids. However, this strategy can only induce long-range correlations and cannot m…
Cryogenic nano-imaging of second-order moiré superlattices
Niels C. H. Hesp, Sergi Batlle-Porro, Roshan Krishna Kumar +7
Second-order superlattices form when moiré superlattices of similar periodicities interfere with each other, leading to even larger superlattice periodicities. These crystalline st…
