Microscopic origin of the nemato-elastic coupling and dynamics of hybridized collective nematic-phonon excitations
Morten H. Christensen, Michael Schütt, Avraham Klein +1
Electronically-driven nematic order breaks the rotational symmetry of a system, e.g., through a Pomeranchuk instability of the Fermi surface, with a concomitant distortion of the l…
Strong Coupling Theory of Superconductivity and Ferroelectric Quantum Criticality in metallic SrTiO
Sudip Kumar Saha, Maria N. Gastiasoro, Jonathan Ruhman +1
Superconductivity in doped SrTiO has remained an enduring mystery for over 50 years. The material's status as a ``quantum" ferroelectric metal, characterized by a soft polar mo…
Singlet, triplet, and mixed all-to-all pairing states emerging from incoherent fermions
Jagannath Sutradhar, Jonathan Ruhman, Avraham Klein
The electron-electron and electron-phonon coupling in complex materials can be more complicated than simple density-density interactions, involving intertwined dynamics of spin, ch…
Multiferroicity in plastically deformed SrTiO
Xi Wang, Anirban Kundu, Bochao Xu +6
A major challenge in the development of quantum technologies is to induce additional types of ferroic orders into materials that exhibit other useful quantum properties. Various te…
A theory of criticality for quantum ferroelectric metals
Avraham Klein, Vladyslav Kozii, Jonathan Ruhman +1
A variety of compounds, for example doped paraelectrics and polar metals, exhibit both ferroelectricity and correlated electronic phenomena such as low-density superconductivity an…
Chiral to Nematic Crossover in the Superconducting State of 4Hb-TaS
I. Silber, S. Mathimalar, I. Mangel +10
Most superconductors have an isotropic, single component order parameter, and are well described by the BCS theory for superconductivity. Unconventional, multiple components superc…
