Ferroelectric superconductivity in noncentrosymmetric metals
Jason G. Kattan, T. Pereg-Barnea
It has recently been shown in experiments that certain materials can display both superconductivity and ferroelectricity, contrary to a long-standing conjecture that these two phen…
Optical conductivity of a topological system driven using a realistic pulse
Ranjani Seshadri, T. Pereg-Barnea
The effect of a time-periodic perturbation, such as radiation, on a system otherwise at equilibrium has been studied in the context of Floquet theory with stationary states replace…
Visualizing near-coexistence of massless Dirac electrons and ultra-massive saddle point electrons
Abhay Kumar Nayak, Jonathan Reiner, Hengxin Tan +8
Strong singularities in the electronic density of states amplify correlation effects and play a key role in determining the ordering instabilities in various materials. Recently hi…
Charged magnons on the surface of a topological insulator
I. Martinez-Berumen, W. A. Coish, T. Pereg-Barnea
We study a system of two-dimensional Dirac electrons (as is realized on the surface of a 3D topological insulator) coupled to an array of localized spins. The spins are coupled fer…
Tunnelling theory of Weyl semimetals in proximity to a metallic band
L. Goutte, T. Pereg-Barnea
We study the effects of tunnelling on the band structure and Fermi arc of a time-reversal broken Weyl semimetal (WSM). When coupled to a non-magnetic parabolic band, the WSM's chir…
Strain-induced superconductivity in Sr2IrO4
Lena Engström, Chia-Chuan Liu, William Witczak-Krempa +1
Multi-orbital quantum materials with strong interactions can host a variety of novel phases. In this work we study the possibility of interaction-driven superconductivity in the ir…
