Terahertz spectroscopy on Faraday and Kerr rotations in a quantum anomalous Hall state

Nature Communications, 2016
Quantized magnetoelectric coupling, which induces exotic magneto-optical phenomena, awaits to be evidenced in topological insulators. Here, Okada et al.

Holographic Nuclear Physics

, 2009
We analyze the phases of the Sakai-Sugimoto model at finite temperature and baryon chemical potential. Baryonic matter is represented either by 4-branes in the 8-branes or by strings stretched from the 8-branes to the horizon.

Strain-tuning for superconductivity in La3Ni2O7 thin films

Communications Physics
The recent discovery of high-transition temperature (T c) superconductivity in pressurized La3Ni2O7 bulk crystals has attracted keen attention for its characteristic energy diagram of e g orbitals containing nearly half-filled  $${d}_{{3}{z}^{2}-{r}^{2}}$

Ultrafast nematic-orbital excitation in FeSe

Nature Communications, 2019
Several experiments have shown evidence for unusual nematic electronic behaviour in unconventional superconductors. Here the authors use pump-probe spectroscopy to observe out-of-equilibrium behaviour of coupled nematic-orbital excitations in iron ...

Challenges in QCD matter physics --The scientific programme of the Compressed Baryonic Matter experiment at FAIR [PDF]

, 2017
Substantial experimental and theoretical efforts worldwide are devoted to explore the phase diagram of strongly interacting matter. At LHC and top RHIC energies, QCD matter is studied at very high temperatures and nearly vanishing net-baryon densities ...

Generic conditions for stable hybrid stars

, 2013
We study the mass-radius curve of hybrid stars, assuming a single first-order phase transition between nuclear and quark matter, with a sharp interface between the quark matter core and nuclear matter mantle.

Signals of the QCD Phase Transition in the Heavens [PDF]

, 2007
The modern phase diagram of strongly interacting matter reveals a rich structure at high-densities due to phase transitions related to the chiral symmetry of quantum chromodynamics (QCD) and the phenomenon of color superconductivity.

Kaons in Dense Half-Skyrmion Matter

, 2009
Dense hadronic matter at low temperature is expected to be in crystal and at high density make a transition to a {\em chirally restored but color-confined} state which is a novel phase hitherto unexplored.

Strongly enhanced shift current at exciton resonances in a noncentrosymmetric wide-gap semiconductor

Nature Communications
Excitons are fundamental quasiparticles that are ubiquitous in photoexcited semiconductors and insulators. Despite causing a sharp and strong photoabsorption near the interband absorption edge, charge-neutral excitons do not yield photocurrent in ...

Is Dark Matter made up of Massive Quark Objects? [PDF]

, 1998
We suggest that dark matter is made up of massive quark objects that have survived from the Big Bang, representing the ground state of ``baryonic'' matter.
