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 ...

Electron Holography: phases matter [PDF]

Microscopy, 2013
Essentially, all optics is wave optics, be it with light, X-rays, neutrons or electrons. The information transfer from the object to the image can only be understood in terms of waves given by amplitude and phase. However, phases are difficult to measure: for slowly oscillating waves such as sound or low-frequency electromagnetic waves, phases can be ...

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.

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.

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 ...

Giant magneto-optical responses in magnetic Weyl semimetal Co3Sn2S2

Nature Communications, 2020
The evidence of topological origin for the recently observed anomalous Hall effect remains elusive. Here, the authors report that the resonance of the optical Hall conductivity resulted from topological electronic structure gives rise to the large ...

Neutron matter - Quark matter phase transition and Quark star

, 1993
We consider the neutron matter quark matter phase transition along with possible existence of hybrid quark stars. The equation of state for neutron matter is obtained using a nonperturbative method with pion dressing of the neutron matter and an analysis

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.
