Bandwidth-Limited Critical Currents in Electrically Tunable Moiré Bands
Riccardo Bertini, Xueqiao Wang, Sergey Slizovskiy +16
Moiré superlattices host narrow minibands whose bandwidth governs correlated and topological phases. Here, we demonstrate that the bandwidth also sets the critical current for the…
Imaging superconducting weak spots through vortex-assisted THz near-field photovoltage
Sergio J. SalvÃa-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…
Fluctuation-enhanced electron-phonon coupling in FeSe
Jovan BlagojeviÄ, Ana MilosavljeviÄ, Tea Belojica +13
The interactions among lattice, charge, and spin degrees of freedom fundamentally shape material properties. In FeSe, symmetry-breaking perturbations serve as highly sensitive prob…
Benchmarking First-Principles Approaches for Extracting Magnetic Exchange Interactions
Nafise Rezaei, Artem R. Oganov, Ali Ghojavand +2
Magnetic exchange interactions govern the macroscopic magnetic behavior of solids and underpin both fundamental spin phenomena and emerging technologies. The accurate and efficient…
Berezinskii-Kosterlitz-Thouless transition with enhanced phase stiffness in -wave strongly coupled two-dimensional superconductors
Sathish Kumar Paramasivam, Andrea Perali, Milorad V. MiloÅ¡eviÄ
We reveal the key role of the -wave symmetry of the superconducting gap in strongly coupled two-dimensional superconductors in determining the properties of the Berezinskii-Kost…
Linearly polarized light enables chiral edge transport in quasi-2D Dirac materials
Mohammad Shafiei, Farhad Fazileh, Milorad V. MiloÅ¡eviÄ
Floquet engineering with high-frequency light offers dynamic control over topological phases in quantum materials. While in 3D Dirac systems circularly polarized light is known to…
