From quantum matter to high-temperature superconductivity in copper oxides
TLDR
The discovery of high-temperature superconductivity in the copper oxides in 1986 triggered a huge amount of innovative scientific inquiry but unresolved issues include the astonishing complexity of the phase diagram, the unprecedented prominence of various forms of collective fluctuations, and the simplicity and insensitivity to material details of the ‘normal’ state at elevated temperatures.
String Theory, Quantum Phase Transitions, and the Emergent Fermi Liquid
TLDR
It is found that the mathematics of string theory is capable of describing fermionic quantum critical states, and the spectral functions of fermions in the field theory are computed.
Holographic duality and the resistivity of strange metals
Department of Physics, Harvard University, Cambridge MA 02138, USA(Dated: December 16, 2013)We present a strange metal, described by a holographic duality, which reproduces the famouslinear…
Electronic structure of the parent compound of superconducting infinite-layer nickelates
TLDR
X-ray spectroscopy and density functional theory are used to show that the electronic structure of the parent compound of superconducting infinite-layer nickelates, while similar to the copper-based high-temperature superconductors, has significant differences.
Quantum critical behaviour in a high-Tc superconductor
TLDR
It is demonstrated that the experimentally measured phase angle agrees precisely with the exponent of the optical conductivity, which points towards a quantum phase transition of an unconventional kind in the high-Tc superconductors.
Incoherent strange metal sharply bounded by a critical doping in Bi2212
TLDR
It is observed that near the Brillouin zone boundary, the strange metal, characterized by an incoherent spectral function, abruptly reconstructs into a more conventional metal with quasiparticles above the temperature of superconducting fluctuations, and that the pseudogap also discontinuously collapses at the very same value of pc.
Fluctuations in finite density holographic quantum liquids
A bstractWe study correlators of the global U(1) currents in holographic models which involve $ \mathcal{N}=4 $ SYM coupled to the finite density matter in the probe brane sector. We find the…
Fermions and the AdS/CFT correspondence: quantum phase transitions and the emergent Fermi-liquid
A central mystery in quantum condensed matter physics is the zero temperature quantum phase transition between strongly renormalized Fermi-liquids as found in heavy fermion intermetallics and…
Spin-orbital frustrations and anomalous metallic state in iron-pnictide superconductors
We develop an understanding of the anomalous metal state of the parent compounds of recently discovered iron-based superconductors starting from a strong-coupling viewpoint, including orbital degrees…
Rapid change of superconductivity and electron-phonon coupling through critical doping in Bi-2212
Conspiring interactions in a cuprate More than 30 years after the discovery of high-temperature superconductivity in copper oxides, its mechanism remains a mystery. Electron pairing mediated solely…
