Superconductivity from interband coupling to ferroelectric quantum critical fluctuations in two dimensions
Sudip Kumar Saha, Jonathan Ruhman, Avraham Klein
Soft critical fluctuations associated with ferroelectric quantum phase transitions are typically transverse owing to their polar nature. This implies that the conventional density-…
Competing incommensurability, electronic correlations, and superconductivity in a hybrid transition metal dichalcogenide
Jean C. Souza, Moshe Haim, Lorenzo Crippa +8
The engineering of superlattices in two-dimensional van der Waals materials has enabled the realization of rich phase diagrams hosting topological and strongly correlated phases. W…
Reduced pair breaking from extended disorder in unconventional superconductors: implications to 4Hb-TaS
Yuval Tsur, Mark H. Fischer, Jonathan Ruhman
Unconventional superconductivity is generally expected to be strongly suppressed by nonmagnetic disorder, as captured by Abrikosov--Gor'kov (AG) theory. However, several materials,…
Interlayer Charge-Transfer Ferroelectric Fluctuations as a Pairing Mechanism in van der Waals Superconductors
Ankan Biswas, Jagannath Sutradhar, Sudip Kumar Saha +2
Signatures of unconventional superconductivity have been reported in a wide range of van der Waals (vdW) materials. However, their microscopic origin remains unclear due to competi…
Mixed Triplet-Singlet Order Parameter in Decoupled Superconducting 1H Monolayers of Transition-Metal Dichalcogenides
Avior Almoalem, Sajilesh Kunhiparambath, Roni Anna Gofman +9
Understanding the emergence of unconventional superconductivity, where the order parameter deviates from simple isotropic s-wave pairing, is a central puzzle in condensed matter ph…
The Smearing of Quasi-Particles: Signatures in the Entanglement Entropy of Excited Many-Particle Systems
Jagannath Sutradhar, Jonathan Ruhman, Avraham Klein +2
The entanglement spectrum serves as a powerful tool for probing the structure and dynamics of quantum many-body systems, revealing key information about symmetry, topology, and exc…
