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…
Unbiased large- approach to competing vestigial orders of density-wave and superconducting instabilities
Grgur Palle, Rafael M. Fernandes
When a primary order breaks multiple symmetries, partially ordered phases that only break a subset of those symmetries, known as vestigial phases, may onset at a higher temperature…
Hopf symmetry protected topological phases in the vicinity of spin orders
Grgur Palle
Hopf terms are topological theta terms that are associated with a host of interesting physics, including anyons, statistical transmutation, chiral edge states, and the spin quantum…
Elastic Quantum Criticality in Nematics and Altermagnets via the Elasto-Caloric Effect
Charles R. W. Steward, Grgur Palle, Markus Garst +2
The coupling between electronic nematic degrees of freedom and acoustic phonons is known to significantly alter the universality class of a nematic quantum critical point (QCP). Wh…
Unconventional Superconductivity in Correlated, Multiband, and Topological Systems
Grgur Palle
In this thesis, we theoretically examine the pairing mechanisms and the identification of the pairing symmetry of unconventional superconductors whose normal states are correlated,…
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…
