TL;DR: In this paper, the authors investigated magnetotransport properties in the bilayer quantum Hall state at the total filling factor of the total electron density and the density difference between the two layers, and demonstrated the emergence of the canted antiferromagnetic (CAF) phase between the ferromagnetic phase and the spin-singlet phase.

TL;DR: In this paper, the 2nd order recombination rates and spin-exchange relaxation of atomic deuterium (D) in a4He coated sample cell, using the hyperfine resonance of β(F = 1/2, mF = −1/2) − δ (F = 3/2), mF= −1 /2) transition in a low magnetic field (3.9 mT) at temperatures between 0.6 K and 1.2 K.

TL;DR: In this article, the authors investigated the domain structure of pseudospins, a soliton lattice in the bilayer quantum Hall state at total Landau level filling factor (L 1 ) in a tilted magnetic field, where the pseudospin represents the layer degree of freedom.

TL;DR: The relationship between the universal conductance fluctuation and the weak localization effect in monolayer graphene is investigated in this article, where the authors find that the ratio of the elastic intervalley scattering time to the inelastic dephasing time varies in accordance with the conductance fluctuations.

TL;DR: In this article, a microwave single-photon detector was developed with highly-excited alkaline Rydberg-atoms in a cooled resonant cavity to search for dark matter axions.
