Direct Evidence of Unconventional Superconductivity in Doped Kagome system RVSb
Avior Almoalem, Yuqing Xing, Iksu Jang +7
The superconducting pairing symmetry of kagome metals remains a central unresolved question largely because phase-sensitive experiments capable of distinguishing between different…
Thermodynamic Discovery of Tetracriticality and Emergent Multicomponent Superconductivity in UTe
Sahas Kamat, Jared Dans, Shanta Saha +4
The candidate topological superconductor UTe exhibits a complex phase diagram with multiple superconducting states, yet the nature of their coexistence has remained a central m…
Superconductivity in kagome metals due to soft loop-current fluctuations
Daniel J. Schultz, Grgur Palle, Asimpunya Mitra +3
We demonstrate that soft fluctuations of translation symmetry-breaking loop currents provide a mechanism for unconventional superconductivity in kagome metals that naturally addres…
Obstructed Cooper pairs in flat band systems -- weakly-coherent superfluids and exact spin liquids
Tamaghna Hazra, Nishchhal Verma, Jörg Schmalian
Superconductivity in a partially filled flat band presents a vexing conceptual hurdle because the absence of a Fermi surface precludes a weak-coupling regime where one can extend i…
Pairing at a single Van Hove point
Risto Ojajärvi, Andrey V. Chubukov, Yueh-Chen Lee +2
We show that an interacting electronic system with a single ordinary or extended Van Hove point, which crosses the Fermi energy, is unstable against triplet superconductivity. The…
Unconventional superconductivity from electronic dipole fluctuations
Grgur Palle, Jörg Schmalian
We study electron-electron Coulomb interactions in electronic systems whose Fermi surfaces possess a finite electric dipole density. Although there is no net dipole moment, we show…
Binding zero modes with fluxons in Josephson junctions of time-reversal invariant topological superconductors
Gabriel F. Rodríguez Ruiz, Adrian Reich, Alexander Shnirman +2
We study the joint dynamics of the phase bias and the propagating Majorana fermions of the edge modes in Josephson junctions containing 2D time-reversal invariant topological s…
Odd-frequency superfluidity from a particle-number-conserving perspective
K. Thompson, U. Zülicke, J. Schmalian +2
We investigate odd-in-time - or odd-frequency - pairing of fermions in equilibrium systems within the particle-number-conserving framework of Penrose, Onsager and Yang, where super…
Superconductivity due to fluctuating loop currents
Grgur Palle, Risto Ojajärvi, Rafael M. Fernandes +1
Orbital magnetism and the loop currents (LC) that accompany it have been proposed to emerge in many systems, including cuprates, iridates, and kagome superconductors. In the case o…
Identification of multiple-flux-quanta vortices by core states in the two-band superconductor Pb
Thomas Gozlinski, Qili Li, Rolf Heid +5
Superconductors are of type I or II depending on whether they form an Abrikosov vortex lattice. Although bulk lead (Pb) is classified as a prototypical type-I superconductor, we ob…
Elastocaloric determination of the phase diagram of SrRuO
You-Sheng Li, Markus Garst, Jörg Schmalian +11
One of the main developments in unconventional superconductivity in the past two decades has been the discovery that most unconventional superconductors form phase diagrams that al…
Topologically enabled superconductivity
Michael A. Rampp, Elio J. König, Jörg Schmalian
Majorana zero modes are a much sought-after consequence of one-dimensional topological superconductivity. Here, we show that, in turn, zero modes accompanying dynamical instanton e…
