Competing incommensurability, electronic correlations, and superconductivity in a hybrid transition metal dichalcogenide
Jean C. Souza, Moshe Haim, Lorenzo Crippa +8
The engineering of superlattices in two-dimensional van der Waals materials has enabled the realization of rich phase diagrams hosting topological and strongly correlated phases. W…
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…
Flat band physics in the charge-density wave state of -TaS
Amir Dalal, Jonathan Ruhman, Jörn W. F. Venderbos
1-TaS is the only insulating transition-metal dichalcogenide (TMD) with an odd number of electrons per unit cell. This insulating state is non-magnetic, making it a potentia…
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…
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…
The Orbitally Selective Mott Phase in Electron Doped Twisted TMDs: A Possible Realization of the Kondo Lattice Model
Amir Dalal, Jonathan Ruhman
Moiré super-potentials in two-dimensional materials allow unprecedented control of the ratio between kinetic and interaction energy. By this, they pave the way to study a wide vari…
Ferromagnetic and Nematic Non-Fermi Liquids in Spin-Orbit Coupled Two-Dimensional Fermi Gases
Jonathan Ruhman, Erez Berg
We study the fate of a two-dimensional system of interacting fermions with Rashba spin-orbit coupling in the dilute limit. The interactions are strongly renormalized at low densiti…
Competition Between Kondo Screening and Magnetism at the LaAlO/SrTiO Interface
Jonathan Ruhman, Arjun Joshua, Shahal Ilani +1
We present a theory of magnetic and magneto-transport phenomena at LaAlO/SrTiO interfaces, which as a central ingredient includes coupling between the conduction bands and…
A Gate-tunable Polarized Phase of Two-Dimensional Electrons at the LaAlO3/SrTiO3 Interface
Arjun Joshua, J. Ruhman, S. Pecker +2
Controlling the coupling between localized spins and itinerant electrons can lead to exotic magnetic states. A novel system featuring local magnetic moments and extended 2D electro…
A Universal Critical Density Underlying the Physics of Electrons at the LaAlO3/SrTiO3 Interface
Arjun Joshua, S. Pecker, J. Ruhman +2
The two-dimensional electron system formed at the interface between the insulating oxides LaAlO3 and SrTiO3 exhibits ferromagnetism, superconductivity, and a wide range of unique m…
