Josephson effects in twisted nodal superconductors

  title={Josephson effects in twisted nodal superconductors},
  author={Pavel A. Volkov and Shu Yang Frank Zhao and Nicola Poccia and Xiaomeng Cui and Philip Kim and Jedediah H. Pixley},
Motivated by the recent proposals for unconventional emergent physics in twisted bilayers of nodal superconductors, we study the peculiarities of the Josephson effect at the twisted interface between d-wave superconductors. We demonstrate that for clean interfaces with a twist angle θ0 in the range 0◦ < θ0 < 45 ◦ the critical current can exhibit nonmonotonic temperature dependence with a maximum at a nonzero temperature as well as a complex dependence on the twist angle at low temperatures. The… 

Doping a moir\'e Mott Insulator: A t-J model study of twisted cuprates

We theoretically investigate twisted structures where each layer is composed of a strongly correlated material. In particular, we study a twisted t-J model of cuprate multilayers within the

Interaction-induced velocity renormalization in magic-angle twisted multilayer graphene

Twistronics heterostructures provide a novel route to control the electronic single particle velocity and thereby to engineer strong effective interactions. Here we show that the reverse may also

High-Temperature Majorana Zero Modes.

We employ analytical and numerical approaches to show that unpaired Majorana zero modes can occur in cores of Abrikosov vortices at the interface between a three-dimensional topological insulator,



Magic angles and current-induced topology in twisted nodal superconductors

Motivated by the recent achievements in the realization of strongly correlated and topological phases in twisted van der Waals heterostructures, we study the low-energy properties of a twisted

Unconventional superconductivity in magic-angle graphene superlattices

The realization of intrinsic unconventional superconductivity is reported—which cannot be explained by weak electron–phonon interactions—in a two-dimensional superlattice created by stacking two sheets of graphene that are twisted relative to each other by a small angle.

Superconductors, orbital magnets and correlated states in magic-angle bilayer graphene

This study shows that broken-symmetry states, interaction-driven insulators, orbital magnets, states with non-zero Chern numbers and superconducting domes occur frequently across a wide range of moiré flat band fillings, including close to charge neutrality.

Tuning superconductivity in twisted bilayer graphene

This study demonstrates twisted bilayer graphene to be a distinctively tunable platform for exploring correlated states by inducing superconductivity at a twist angle larger than 1.1°—in which correlated phases are otherwise absent—by varying the interlayer spacing with hydrostatic pressure.

Time-Reversal Symmetry Breaking States in High-Temperature Superconductors

The d x 2 _ y2 - wave symmetry of the order parameter leads to various physical phenomena of high-temperature superconductors which are not present in standard superconductors. A particularly

Electrostatic effects, band distortions, and superconductivity in twisted graphene bilayers

It is shown that the modulation of the charge density significantly modifies the electronic structure, which can make an important contribution to superconductivity through electron-assisted hopping.

Superconductivity and strong correlations in moiré flat bands

Strongly correlated systems can give rise to spectacular phenomenology, from high-temperature superconductivity to the emergence of states of matter characterized by long-range quantum entanglement.

Theory of correlated insulating behaviour and spin-triplet superconductivity in twisted double bilayer graphene

A twisted double bilayer graphene is studied, where ferromagnetic insulator and spin triplet superconducting phases can be stabilized and a novel orbital effect arising from in-plane fields plays an important role in interpreting experiments.

Graphene bilayers with a twist

This Review highlights some key research results in this field, point to important questions that remain open and comment on the place of magic-angle twisted bilayer graphene in the strongly correlated quantum matter world.
