Observation of the quantum Hall effect in δ-doped SrTiO3

Nature Communications, 2016
Observation of quantum phenomena in correlated electron systems is challenging due to low mobility and high concentration of carriers. Here, Matsubara et al.

Liquid-gas phase transition in hot asymmetric nuclear matter with density-dependent relativistic mean-field models

, 2013
The liquid-gas phase transition in hot asymmetric nuclear matter is studied within density-dependent relativistic mean-field models where the density dependence is introduced according to the Brown-Rho scaling and constrained by available data at low ...

Zero-bias photocurrent in ferromagnetic topological insulator

Nature Communications, 2016
By magnetic-doping, the electronic band structure of a topological insulator can be significantly altered to yield functional behaviour. Here, the authors demonstrate a large photocurrent response, and its control, under zero-bias in an optimally ...

Quark deconfinement in neutron star cores and the ground state of neutral matter

, 2007
Whether or not deconfined quark phase exists in neutron star cores and represents the ground state of neutral matter at moderate densities are open questions.

First Principle Study on the Z-Type Characteristic Modulation of GaN/g-C₃N₄ Heterojunction

Molecules
This study investigates the stability, electronic structure, and optical properties of the GaN/g-C3N4 heterojunction using the plane wave super-soft pseudopotential method based on first principles. Additionally, an external electric field is employed to

Nucleation of quark matter in protoneutron star matter

, 2010
The phase transition from hadronic to quark matter may take place already during the early post-bounce stage of core collapse supernovae when matter is still hot and lepton rich.

Phase transition from nuclear matter to color superconducting quark matter: the effect of the isospin

, 2010
We compute the mixed phase of nuclear matter and 2SC matter for different temperatures and proton fractions. After showing that the symmetry energy of the 2SC phase is, to a good approximation, three times larger than the one of the normal quark phase ...

Superconductivity in a chiral nanotube

Nature Communications, 2017
Chirality affects many properties of materials, but how it affects superconductivity remains unclear. Here, Qinet al. report nonreciprocal supercurrent flows in individual nanotubes of WS2via ionic gating, evidencing chiral superconducting transport.
