Phase separation instabilities and pairing modulations in
Kun Fang, G. W. Fernando, A. V. Balatsky +2
There is growing evidence that the unconventional spatial inhomogeneities in the doped high-Tc superconductors are accompanied by the pairing of electrons, subsequent quantum phase…
Quantum critical points and phase separation instabilities in Hubbard nanoclusters
A. N. Kocharian, Kun Fang, G. W. Fernando
Spontaneous phase separation instabilities with the formation of various types of charge and spin pairing (pseudo)gaps in Hubbard model including the {\it next nearest neighb…
Local electronic nematicity in the one-band Hubbard model
Kun Fang, G. W. Fernando, A. K. Kocharian
Nematicity is a well known property of liquid crystals and has been recently discussed in the context of strongly interacting electrons. An electronic nematic phase has been seen b…
Pairing enhancement in Betts lattices with next nearest neighbor couplings: Exact results
Kun Fang, Gayanath Fernando, Armen Kocharian
Electron instabilities in the Hubbard model with the next nearest neighbor coupling are calculated by exact diagonalization in finite, two-dimensional Betts cells (lattices). A via…
Tracing magnetism and pairing in FeTe-based systems
Kalum Palandage, Kun Fang, Gayanath Fernando +1
In order to examine the interplay between magnetism and superconductivity, we monitor the non- superconducting chalcogenide FeTe and follow its transitions under insertion of oxyge…
Phase transitions and entanglement properties in spin-1 Heisenberg clusters with single-ion anisotropy
V S Abgaryan, N S Ananikian, L N Ananikyan +1
The incipient quantum phase transitions of relevance to nonzero fluctuations and entanglement in Heisenberg clusters are studied in this paper by exploiting negativity as a measure…
