The origin of lattice instabilities in layered materials has been controversial for several decades. In this work, the authors disentangle the underlying interplay of electrons and lattice vibrations (phonons) for the prototypical case of a TaS monolayer. They introduce the technique of to the field of electron-phonon physics and identify unambiguously the electronic degrees of freedom that are responsible for the phonon-mode softening. Here, the physics of massive Dirac fermions is shown to drive the lattice instability.

Rather than Poincarè symmetry, it is the invariance under crystal symmetry of space groups that constrains fermions in solids, and thus there might exist some exotic fermions beyond elementary particles in high-energy physics. Here, the authors verify the existence of the long-sought-after sixfold fermions in pyrite PdSb by means of high-resolution ARPES and first-principles calculations. They show that this sixfold degeneracy is a heretofore unknown single fermion node carrying zero Chern number, quite unlike the previously reported sixfold double spin-1 chiral fermions.

The problem of open quantum systems coupled to fermionic environments arises in a variety of fields, ranging from quantum dots to quantum transport at zero and finite temperature. This work presents and analyzes a tensor network based time integration scheme for this problem, which enables simulations of such systems with controllable and certified error. Furthermore, it is shown that performing simulations in the Heisenberg picture can lead to significant efficiency gains.

Surprising singularities occur, almost ubiquitously, when inverting the Bethe-Salpeter equations of fundamental many-fermion models. For systems with repulsive interactions, they were interpreted as nonperturbative manifestations of a progressive suppression of fluctuations. By studying here the case of attractive interactions, the authors provide a counterexample to this interpretation: they find that singularities also affect a dominant sector of the attractive model, the charge channel. The fact that singularities are not confined to suppressed sectors poses additional challenges to the many-fermion theory, whose clarification calls for dedicated studies in the near future.
Ferromagnetism and superconductivity in twisted double bilayer graphene
Fengcheng Wu and Sankar Das Sarma
Phys. Rev. B 101, 155149 (2020) - Published 30 April, 2020
Twisted double bilayer graphene is a highly tunable moiré system to study strongly interacting physics. Here, the authors present a theory of competing ferromagnetic and superconducting orders in this system. They show that the single-particle moiré bands can be drastically modified by a perpendicular electric displacement field. As a result, the ferromagnetic insulating gap driven by Coulomb interaction has a dome shape dependence on the layer potential difference, as observed in several experiments. The stability of the ferromagnetic insulator against collective excitations, including spin and valley magnons, is theoretically verified. Furthermore, the authors investigate the possibility of phonon-mediated intervalley equal-spin pairing, using the property that the acoustic phonon mediated attraction respects an enlarged SU(2)×SU(2) symmetry.
