We discuss evolution of the Fermi surface (FS) topology with doping in electron-doped cuprates within the framework of a one-band Hubbard Hamiltonian, where antiferromagnetism and superconductivity are assumed to coexist in a uniform phase. In the lightly doped insulator, the FS consists of electron pockets around the ðp;0Þ points. The first change in the FS topology occurs in the optimally doped region when an additional hole pocket appears at the nodal point. The second change in topology… Expand

Evolution of the fermi surface of a doped topological insulator with carrier concentration
In an ideal bulk topological-insulator (TI) conducting surface states protected by time reversal symmetry enfold an insulating crystal. However, the archetypical TI, Bi2Se3, is actually neverExpand
Quantum spin fluctuations and evolution of electronic structure in cuprates
Correlation effects in CuO2 layers give rise to a complicated landscape of collective excitations in high-Tc cuprates. Their description requires an accurate account for electronic fluctuations at aExpand
Enhancing superconductivity in A 3 C 60 fullerides
Motivated by the recent experimental report of a possible light-induced superconductivity in A3C60 at high temperature [Mitrano et al., Nature 530, 451 (2016)], we investigate theoretical mechanismsExpand
Multiple Electronic Components and Lifshitz Transitions by Oxygen Wires Formation in Layered Cuprates and Nickelates
There is growing compelling experimental evidence that a quantum complex matter scenario made of multiple electronic components and competing quantum phases is needed to grab the key physics of highExpand
Exotic s-wave superconductivity in alkali-doped fullerides.
TLDR
Recent ab initio calculations confirm that the alkali-doped fullerides are a new type of unconventional superconductors, where the unusual synergy between the phonons and Coulomb interactions drives the high-Tc superconductivity. Expand
Superconductivity and hybrid soft modes in TiSe2
The interplay between superconductivity and charge-density-wave (CDW) order plays a central role in the layered transition-metal dichalcogenides. 1T−TiSe2 forms a prime example, featuringExpand
Progress and perspectives on electron-doped cuprates
Although the vast majority of high-$T_c$ cuprate superconductors are hole-doped, a small family of electron-doped compounds exists. Under investigated until recently, there has been tremendous recentExpand
Temperature-driven spectral weight transfer in doped magnetic insulators
In this thesis we study the effects of finite temperature (T ) on the singleelectron spectral function of doped magnetic insulators. First, we derive the low-temperature correction to the self-energyExpand
Magnetic frustration in a metallic fcc lattice
Magnetic frustration in metals is scarce and hard to pinpoint, but exciting due to the possibility of the emergence of fascinating novel phases. The cubic intermetallic compound HoInCu$_4$ with allExpand
Double band inversion in α -Sn: appearance of topological surface states and the role of orbital composition
The electronic structure of \graySn(001) thin films strained compressively in-plane was studied both experimentally and theoretically. A new topological surface state (TSS) located entirely withinExpand
