Barrier J, Kim M, Krishna Kumar R, Xin N, Kumaravadivel P, Hague L, et al.
Nature . 2024 Apr; 628(8009):741-745. PMID: 38658686
Extensive efforts have been undertaken to combine superconductivity and the quantum Hall effect so that Cooper-pair transport between superconducting electrodes in Josephson junctions is mediated by one-dimensional edge states. This...

Xin N, Lourembam J, Kumaravadivel P, Kazantsev A, Wu Z, Mullan C, et al.
Nature . 2023 Apr; 616(7956):270-274. PMID: 37045919
The most recognizable feature of graphene's electronic spectrum is its Dirac point, around which interesting phenomena tend to cluster. At low temperatures, the intrinsic behaviour in this regime is often...

Berdyugin A, Xin N, Gao H, Slizovskiy S, Dong Z, Bhattacharjee S, et al.
Science . 2022 Jan; 375(6579):430-433. PMID: 35084955
In thermodynamic equilibrium, current in metallic systems is carried by electronic states near the Fermi energy, whereas the filled bands underneath contribute little to conduction. Here, we describe a very...

Moller S, Banszerus L, Knothe A, Steiner C, Icking E, Trellenkamp S, et al.
Phys Rev Lett . 2022 Jan; 127(25):256802. PMID: 35029428
We report on finite bias spectroscopy measurements of the two-electron spectrum in a gate defined bilayer graphene (BLG) quantum dot for varying magnetic fields. The spin and valley degree of...

Garcia-Ruiz A, Thompson J, Mucha-Kruczynski M, Falko V
Phys Rev Lett . 2020 Nov; 125(19):197401. PMID: 33216571
We study electronic contribution to the Raman scattering signals of two-, three- and four-layer graphene with layers at one of the interfaces twisted by a small angle with respect to...

Barrier J, Kumaravadivel P, Krishna Kumar R, Ponomarenko L, Xin N, Holwill M, et al.
Nat Commun . 2020 Nov; 11(1):5756. PMID: 33188210
In quantizing magnetic fields, graphene superlattices exhibit a complex fractal spectrum often referred to as the Hofstadter butterfly. It can be viewed as a collection of Landau levels that arise...

Kim M, Xu S, Berdyugin A, Principi A, Slizovskiy S, Xin N, et al.
Nat Commun . 2020 Jun; 11(1):3054. PMID: 32528007

Phys Rev Lett . 2020 Jun; 124(20):206101. PMID: 32501062
We apply a multiscale modeling approach to study lattice reconstruction in marginally twisted bilayers of transition metal dichalcogenides (TMD). For this, we develop density functional theory parametrized interpolation formulae for...

Berdyugin A, Tsim B, Kumaravadivel P, Xu S, Ceferino A, Knothe A, et al.
Sci Adv . 2020 Jun; 6(16):eaay7838. PMID: 32494602
Magnetic fields force ballistic electrons injected from a narrow contact to move along skipping orbits and form caustics. This leads to pronounced resistance peaks at nearby voltage probes as electrons...

Kim M, Xu S, Berdyugin A, Principi A, Slizovskiy S, Xin N, et al.
Nat Commun . 2020 May; 11(1):2339. PMID: 32393747
Electron-electron interactions play a critical role in many condensed matter phenomena, and it is tempting to find a way to control them by changing the interactions' strength. One possible approach...
