Title: Fermi surface reconstruction in electron-doped cuprates without antiferromagnetic long-range order

Abstract

Fermi surface (FS) topology is a fundamental property of metals and superconductors. In electron-doped cuprate Nd_2-xCe_xCuO₄(NCCO), an unexpected FS reconstruction has been studied in optimal- and overdoped regime (x= 0.15-0.17) by quantum oscillation measurements (QOM). This is all the more puzzling because neutron scattering suggests that the antiferromagnetic (AFM) long-range order, which is believed to reconstruct the FS, vanishes beforex= 0.14. To reconcile the conflict, a widely discussed external magnetic-field–induced AFM long-range order in QOM explains the FS reconstruction as an extrinsic property. Here, we report angle-resolved photoemission (ARPES) evidence of FS reconstruction in optimal- and overdoped NCCO. The observed FSs are in quantitative agreement with QOM, suggesting an intrinsic FS reconstruction without field. This reconstructed FS, despite its importance as a basis to understand electron-doped cuprates, cannot be explained under the traditional scheme. Moreover, the energy gap of the reconstruction decreases rapidly near x = 0.17 like an order parameter, echoing the quantum critical doping in transport. The totality of the data points to a mysterious order betweenx= 0.14 and 0.17, whose appearance favors the FS reconstruction and disappearance defines the quantum critical doping. A recent topological proposal presents an ansatz for its origin.

Superconductivity-Insensitive Order at $q \sim 1 / 4$ in Electron-Doped Cuprates

Journal Article Jang, H. ; Asano, S. ; Fujita, M. ; ... - Physical Review X

One of the central questions in the cuprate research is the nature of the ‘normal state’ which develops into high temperature superconductivity (HTSC). In the normal state of hole-doped cuprates, the existence of charge density wave (CDW) is expected to shed light on the mechanism of HTSC. With evidence emerging for CDW order in the electron-doped cuprates, the CDW would be thought to be a universal phenomenon in high-T_c cuprates. However, the CDW phenomena in electron-doped cuprate are quite different than those in hole-doped cuprates. Here we study the nature of the putative CDW in an electron-doped cuprate through directmore »« less

Angle-Resolved Photoemission Spectroscopy on Electronic Structure and Electron-Phonon Coupling in Cuprate Superconductors

Journal Article Zhou, X J - Submitted to Book Chapter in Handbook of High-Temperature Superconductivity: Theory and Experiment (2007)

In addition to the record high superconducting transition temperature (T{sub c}), high temperature cuprate superconductors are characterized by their unusual superconducting properties below T{sub c}, and anomalous normal state properties above T{sub c}. In the superconducting state, although it has long been realized that superconductivity still involves Cooper pairs, as in the traditional BCS theory, the experimentally determined d-wave pairing is different from the usual s-wave pairing found in conventional superconductors. The identification of the pairing mechanism in cuprate superconductors remains an outstanding issue. The normal state properties, particularly in the underdoped region, have been found to be at oddmore »« less

Journal Article Park, S R ; Leem, C S ; Roh, Y S ; ... - J. Phys. Chem. Solids 69:2939,2008

We report angle resolved photoemission (ARPES) studies on electron-doped cuprate superconductor Sm{sub 2-x}Ce{sub x}CuO{sub 4} (x = 0.14 and 0.18). A wide energy range scan shows clear 'waterfall' effect at an energy scale close to 500 meV which is consistent with the value found in Nd{sub 2-x}Ce{sub x}CuO{sub 4} (NCCO) but larger than that from hole-doped superconductors. High resolution results from both dopings show pseudo-gap effects that were observed in NCCO. However, the effects are found to be stronger than that observed in optimally doped NCCO. The overall electronic structure is well understood within a simple model in which amore »« less
Correlation between scale-invariant normal-state resistivity and superconductivity in an electron-doped cuprate

Journal Article Sarkar, Tarapada ; Mandal, P. R. ; Poniatowski, N. R. ; ... - Science Advances

An understanding of the normal state in the high-temperature superconducting cuprates is crucial to the ultimate understanding of the long-standing problem of the origin of the superconductivity itself. This so-called “strange metal” state is thought to be associated with a quantum critical point (QCP) hidden beneath the superconductivity. In electron-doped cuprates—in contrast to hole-doped cuprates—it is possible to access the normal state at very low temperatures and low magnetic fields to study this putative QCP and to probe the T → 0 K state of these materials. We report measurements of the low-temperature normal-state magnetoresistance (MR) of the n-type cupratemore »« less

Origin of 'Hot Spots' in the pseudogap regime of Nd{sub 1.85}Ce{sub 0.15}CuO{sub 4}: An LDA + DMFT + {sigma}{sub k} study

Journal Article Kokorina, E E ; Kuchinskii, E Z ; Nekrasov, I. A. ; ... - Journal of Experimental and Theoretical Physics

The material-specific electronic band structure of the electron-doped high- T{sub c} cuprate Nd{sub 1.85}Ce{sub 0.15}CuO{sub 4} (NCCO) is calculated in the pseudogap regime using the recently developed generalized LDA + DMFT + {sigma}{sub k} scheme. The LDA/DFT (density-functional theory within local density approximation) provides model parameters (hopping integral values and local Coulomb interaction strength) for the one-band Hubbard model, which is solved by the DMFT (dynamical mean-field theory). To take pseudogap fluctuations into account, the LDA + DMFT is supplied with an 'external' k-dependent self-energy {sigma}{sub k} that describes interaction of correlated conducting electrons with nonlocal Heisenberg-like antiferromagnetic (AFM) spinmore »« less
