Electric field control of superconducting fluctuations and quasiparticle interference at oxide interfaces
Graham Kimbell, Ulderico Filippozzi, Stefano Gariglio +4
We investigate tunable superconducting transitions in (111) field-effect devices. Large increases in conductivity, associated with superconducting…
Upper critical field and pairing symmetry of Ising superconductors
Lena Engström, Ludovica Zullo, Tristan Cren +2
Motivated by the fact that the measured critical field in various transition metal dichalcogenide (TMD) superconductors is poorly understood, we reexamine its scaling beha…
Normal state quantum geometry, non-locality and superconductivity
Florian Simon
We investigate aspects of the relation between the quantum geometry of the normal state (NS) and the superconducting phase, through the lens of non-locality. By relating band theor…
Superconducting and spin-density wave phases probed by scanning tunneling spectroscopy in the organic conductor
Mohammadmehdi Torkzadeh, Pascale Senzier, Claude Bourbonnais +9
By scanning tunneling microscopy (STM) we have probed the local quasi-particle density of states (DOS) of the Bechgaard salt organic superconductor in…
Detecting the topological winding of superconducting nodes via Local Density of States
Lena Engström, Pascal Simon, Andrej Mesaros
Many systems are topologically trivial in the bulk, but still have non-trivial wavefunctions locally in the Brillouin zone. For example, in a small-gap Dirac material the Berry cur…
Persistence of vortexlike phase fluctuations in underdoped to heavily overdoped Bi-2201 cuprates
J. Terzic, Bal K. Pokharel, Z. Z. Li +4
The mechanism that controls the superconducting (SC) transition temperature as a function of doping is one of the central questions in cuprate high-temperature…
High-field superconductivity from atomic-scale confinement and spin-orbit coupling at (111) interfaces
Ulderico Filippozzi, Graham Kimbell, Davide Pizzirani +6
We study the superconducting critical fields of two-dimensional electron systems at (111) interfaces as a function of electrostatic back-gating. Our work r…
Achieving superconductivity in infinite-layer nickelate thin films by aluminum sputtering deposition
Dongxin Zhang, Aravind Raji, Luis M. Vicente-Arche +3
The recent discovery of superconductivity in infinite-layer (IL, ABO) nickelates has opened a new avenue to deepen the understanding of high-temperature superconductivity. Howe…
Superconductivity in PrNiO2 infinite-layer nickelates
Hoshang Sahib, Francesco Rosa, Aravind Raji +6
Several reports about infinite-layer nickelate thin films suggest that the superconducting critical temperature versus chemical doping phase diagram has a dome-like shape, similar…
Transverse resistance due to electronic inhomogeneities in superconductors
Shamashis Sengupta, Alireza Farhadizadeh, Joe Youssef +8
Phase transitions in many-body systems are often associated with the emergence of spatial inhomogeneities. Such features may develop at microscopic lengthscales and are not necessa…
Anisotropy of Yu-Shiba-Rusinov states in NbSe
Mateo Uldemolins, Freek Massee, Tristan Cren +2
The spatial structure of in-gap Yu-Shiba-Rusinov (YSR) bound states induced by a magnetic impurity in a superconductor is the essential ingredient for the possibility of engineerin…
Topologically trivial gap-filling in superconducting Fe(Se,Te) by one dimensional defects
A. Mesaros, G. D. Gu, F. Massee
Structural distortions and imperfections are a crucial aspect of materials science, on the macroscopic scale providing strength, but also enhancing corrosion and reducing electrica…
Unraveling p-type and n-type interfaces in Superconducting Infinite-Layer Nickelate thin films
Aravind Raji, Araceli Gutiérrez-Llorente, Dongxin Zhang +5
After decades of research, superconductivity was finally found in nickel-based analogs of superconducting cuprates, with infinite-layer (IL) structure. These results are so far res…
Quasi one-dimensional organic conductors: from Fröhlich conductivity and Peierls insulating state to magnetically-mediated superconductivity, a retrospective
Denis Jerome, Claude Bourbonnais
It is indisputable that the search for high-temperature superconductivity has stimulated the work on low-dimensional organic conductors at its beginning. Since the discovery of tru…
Interaction-driven quantum phase transition of a single magnetic impurity in Fe(Se,Te)
M. Uldemolins, A. Mesaros, G. D. Gu +4
Understanding the interplay between individual magnetic impurities and superconductivity is crucial for bottom-up construction of novel phases of matter. For decades, the descripti…
Supercurrent Distribution in Real-Space and Anomalous Paramagnetic Response in a Superconducting Quasicrystal
Takumi Fukushima, Nayuta Takemori, Shiro Sakai +2
We theoretically study the real-space distribution of the supercurrent that flows under a uniform vector potential in a two-dimensional quasiperiodic structure. This is done by con…

We study a periodically driven one dimensional Kitaev model in the presence of disorder. In the clean limit our model exhibits four topological phases corresponding to the existenc…
Spontaneous voltage peaks in superconducting Nb channels without engineered asymmetry
Shamashis Sengupta, Miguel Monteverde, Sara Loucif +3
Rectification effects in solid-state devices are a consequence of nonreciprocal transport properties. This phenomenon is usually observed in systems with broken inversion symmetry.…
