Origin of Mott Insulating Behavior and Superconductivity in Twisted Bilayer Graphene [PDF]
Physical Review X, 2018 A remarkable recent experiment has observed Mott insulator and proximate superconductor phases in twisted bilayer graphene when electrons partly fill a nearly flat mini-band that arises a `magic' twist angle.

Quantum cascade of correlated phases in trigonally warped bilayer graphene [PDF]
Nature, 2021 Divergent density of states offers an opportunity to explore a wide variety of correlated electron physics. In the thinnest limit, this has been predicted and verified in the ultraflat bands of magic-angle twisted bilayer graphene1–5, the band touching ...

Sensors, 2021 High-sensitivity and simple, low-cost readout are desirable features for sensors independent of the application area. Micro-cantilever sensors use the deflection induced by the analyte presence to achieve high-sensitivity but possess complex electronic ...

Localized magnetic states in biased bilayer and trilayer graphene [PDF]
, 2009 We study the localized magnetic states of impurity in biased bilayer and trilayer graphene. It is found that the magnetic boundary for bilayer and trilayer graphene presents the mixing features of Dirac and conventional fermion.

Strain fields in twisted bilayer graphene [PDF]
Nature Materials, 2020 Van der Waals heteroepitaxy allows deterministic control over lattice mismatch or azimuthal orientation between atomic layers to produce long-wavelength superlattices.

Cascade of isospin phase transitions in Bernal-stacked bilayer graphene at zero magnetic field [PDF]
Nature Physics, 2021 Emergent phenomena arising from the collective behaviour of electrons is expected when Coulomb interactions dominate over the kinetic energy, and one way to create this situation is to reduce the electronic bandwidth.

Current Opinion in Structural Biology, 2000 Fluctuations, inherent in flexible and biologically relevant lipid bilayers, make quantitative structure determination challenging. Shortcomings in older methods of structure determination have been realized and new methodologies have been introduced that take fluctuations into account.

Photonic analog of bilayer graphene [PDF]
Physical Review B, 2021 Drawing inspiration from bilayer graphene, this paper introduces its photonic analog comprising two stacked graphene-like photonic crystals, that are coupled in the near-field through spoof surface plasmons. Beyond the twist degree of freedom that can radically alter the band structure of the bilayer photonic graphene, the photonic dispersion can be ...

Frontiers in Materials, 2019 In recent years, ultrathin Ag films (UTAFs), which are attractive owing to its extremely low resistance, relatively high transparency, excellent mechanical flexibility, and mature mass production, have been reported as potential candidates to replace ...
