Strong-coupling superconductivity near Gross-Neveu quantum criticality in Dirac systems
Veronika C. Stangier, Daniel E. Sheehy, Jörg Schmalian
We study two-dimensional massless Dirac fermions at neutrality, coupled to bosonic modes through a Yukawa interaction. We then examine the intriguing possibility that such a system…
Superconductivity of Incoherent Electrons near the Relativistic Mott Transition in Twisted Dirac Materials
Veronika C. Stangier, Mathias S. Scheurer, Daniel E. Sheehy +1
We demonstrate that superconductivity driven by strong quantum-critical fluctuations can emerge near relativistic Mott transitions in twisted two-dimensional materials, taking on a…
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…
Magnetic-field-tuned randomness in inhomogeneous altermagnets
Anzumaan R. Chakraborty, Jörg Schmalian, Rafael M. Fernandes
Altermagnetic (AM) states have compensated collinear magnetic configurations that are invariant under a combination of real-space rotation and time reversal. While these symmetries…
Local spectroscopy of loop current order with individual magnetic atoms
Jiangchang Zheng, Caiyun Chen, Xu Zhang +16
Hidden ordered states--characterized by order parameters that elude conventional probes--pose a fundamental challenge for their identification in quantum materials. Recent experime…
Elasto-Hall conductivity and the anomalous Hall effect in altermagnets
Keigo Takahashi, Charles R. W. Steward, Masao Ogata +2
Altermagnets break time-reversal symmetry, preserve the crystal translation invariance, and have a spin density with -wave, -wave, etc. momentum dependencies which do not con…
Extended strange metal regime from superconducting puddles
Noga Bashan, Evyatar Tulipman, Steven A. Kivelson +2
We study a model of mesoscale superconducting puddles in a metal, represented as dynamical impurities interacting with a finite number of electronic channels via Andreev and normal…
