Superconducting dome due to the Fano-Feshbach shape resonance in artificial high-Tc superlattices
Gaetano Campi, Andrea Alimenti, Danielle Villa +7
In this work we provide compelling experimental validation of the Bianconi Perali Valletta (BPV) theory predicting a superconducting dome based on a quantum material design of Arti…
The charge density fluctuations and the Shrinking Fermi Liquid scenario for strange metallicity in cuprates
Sergio Caprara, Sauri Bhattacharyya, Carlo Di Castro +3
We interpret the strange metal (SM) properties of slightly overdoped cuprates in terms of the recently proposed Shrinking Fermi Liquid theory. This is based on the pervading presen…
Anomalous thermopower from the drag of overdamped collective modes
G. Mirarchi, G. Seibold, M. Grilli +1
Inspired by the observation of a Seebeck coefficient ratio that exhibits a seemingly logarithmic divergence at low temperature in high-temperature superconducting cuprates, we show…
Unveiling the Interplay of Charge and Magnetic Excitations in HgBaCaCuO
Karn Rongrueangkul, Martina Fedele, Leonardo Martinelli +10
Unraveling the mechanism that binds electrons into Cooper pairs in cuprate high-temperature superconductors remains one of the most fundamental challenges in condensed-matter physi…
Majorana fermions at self-generated interfaces
Nikola Prodanov, Sergio Ciuchi, Sergio Caprara
The Kitaev model describing a one-dimensional topological superconducting chain is known to support two Majorana fermions localized at the systems endpoints when the parameters are…
Electron-phonon coupling revealed by charge density fluctuations in cuprate superconductors
Martina Fedele, Giacomo Merzoni, Marco Moretti Sala +6
Electron-phonon coupling (EPC) governs lattice dynamics, charge transport, and collective electronic phases in quantum materials. In several families of unconventional superconduct…
