Stacking-tuned superconductivity and competing charge-density-wave states in NbSe
Sandra Sajan, Xinze Yang, Haojie Guo +9
Layer stacking provides a powerful yet underexplored route for reshaping collective quantum order in van der Waals materials. Here we use high-resolution scanning tunneling microsc…
Gapless superconductivity from extremely dilute magnetic disorder in 2H-NbSe2-xSx
Jose Antonio Moreno, Mercè Roig, Víctor Barrena +14
Most superconducting materials exhibit a vanishing density of states at the Fermi level and Anderson's theorem posits that the superconducting gap is robust against nonmagnetic dis…
Study of charge density waves in suspended 2H-TaS2 and 2H-TaSe2 by nanomechanical resonance
Martin Lee, Makars Šiškins, Samuel Mañas-Valero +3
The charge density wave (CDW) state in van der Waals systems shows interesting scaling phenomena as the number of layers can significantly affect the CDW transition temperature, $T…
Coherent coupling between vortex bound states and magnetic impurities in 2D layered superconductors
Sunghun Park, Vıctor Barrena, Samuel Mañas-Valero +9
Bound states in superconductors are expected to exhibit a spatially resolved electron-hole asymmetry which is the hallmark of their quantum nature. This asymmetry manifests as osci…
Low frequency imaginary impedance at the superconducting transition of 2H-NbSe
David Perconte, Samuel Manas-Valero, Eugenio Coronado +2
The superconducting transition leads to a sharp resistance drop in a temperature interval that can be a small fraction of the critical temperature T. A superconductor exactly a…
Pressure induced collapse of the charge density wave and Higgs mode visibility in 2H-TaS
Romain Grasset, Yann Gallais, Alain Sacuto +4
The pressure evolution of the Raman active electronic excitations of the transition metal dichalcogenides 2H-TaS is followed through the pressure phase diagram embedding incomm…
