Anomalous transport in the Aubry-André-Harper model in isolated and open systems

Archak Purkayastha, Sambuddha Sanyal, Abhishek Dhar, and Manas Kulkarni

Phys. Rev. B 97, 174206 (2018) - Published 24 May, 2018

There are two well-established ways of characterizing transport properties. The first is via the spread of correlations in an isolated system. The second is through the system-size dependence of the current, when a potential bias is applied by connecting the two ends of the system to reservoirs. These are two different experiments, but usually the result of one experiment can be inferred from that of the other. This work presents a surprising counterexample. The authors show that, at the critical point of the Aubry-André-Harper model, transport in the presence of reservoirs is drastically different from transport in the isolated system. The scaling of current with system size shows clear subdiffusive behavior, while the spread of correlations does not show any subdiffusive behavior. It actually hints at superdiffusion. This implies that the understanding of the relation between transport in open and in isolated systems needs to be reexamined.

Sum-frequency ionic Raman scattering

Dominik M. Juraschek and Sebastian F. Maehrlein

Phys. Rev. B 97, 174302 (2018) - Published 16 May, 2018

Coherently excited phonons are a unique tool to control the properties of materials in their electronic ground state on the picosecond timescale. Here, the authors complete the map of four excitation mechanisms for Raman-active phonons, which are either directly mediated by photons or work with the help of nonlinearly coupled phonons. Each process can be achieved by using a sum- or difference-frequency mixing of the scattering particles. The general model here captures all four mechanisms, which is demonstrated for different types of material using density functional theory. This study may serve as a guide for the selective excitation of phonons and Raman-active modes in general.

Pair density waves in superconducting vortex halos

Yuxuan Wang, Stephen D. Edkins, Mohammad H. Hamidian, J. C. Séamus Davis, Eduardo Fradkin, and Steven A. Kivelson

Phys. Rev. B 97, 174510 (2018) - Published 14 May, 2018

The authors analyze the interplay between a d-wave uniform superconducting and a pair-density-wave order (PDW) parameter in the neighborhood of a vortex, and compute the resulting local density of states in the vortex halo. The intertwining of the two superconducting orders leads to a charge density modulation with the same periodicity as the PDW, which is twice the period of the charge density wave that arises as a second harmonic of the PDW itself. They discuss key features of the charge density modulation that can be directly compared with recent results from scanning tunneling microscopy and speculate on the role PDW order may play in the global phase diagram of the hole-doped cuprates.

Pair-density waves, charge-density waves, and vortices in high-Tc cuprates

Zhehao Dai, Ya-Hui Zhang, T. Senthil, and Patrick A. Lee

Phys. Rev. B 97, 174511 (2018) - Published 14 May, 2018

The authors analyze a recent STM experiment, reporting a period-8 charge density wave (CDW) in the vortex halo in striking contrast to the period-4 CDWs that are commonly observed in the cuprates. Inside the superconducting dome, the observation of CDWs necessarily implies the existence of a pair density wave (PDW) at the same momentum, as suggested by various theoretical proposals. The authors discuss distinct experimental features, which distiguish the case where this newly reported CDW is driven by a PDW and the case where the CDW is the primary order, and suggest follow-up experiments in order to distinguish unambiguously these two scenarios. The PDW-driven scenario is then put into a broader context in relation to the pseudo-gap phenomenology, Hc2, and different kinds of CDWs.

Anisotropy of the upper critical field and its thickness dependence in superconducting FeSe electric-double-layer transistors

Junichi Shiogai, Shojiro Kimura, Satoshi Awaji, Tsutomu Nojima, and Atsushi Tsukazaki

Phys. Rev. B 97, 174520 (2018) - Published 29 May, 2018

High-temperature superconductivity in FeSe thin films has attracted keen interest owing to the counterintuitive enhancement of the superconducting critical parameters in the monolayer-thin limit. Here, the authors apply an electrochemical etching technique to the FeSe-based electric-double-layer transistor (FeSe-EDLT) to investigate systematically the thickness and angular dependence of the upper critical magnetic field (Hc2) below 10 nm. Compared with the isotropic Hc2 in low-Tc bulk FeSe, the high-Tc FeSe-EDLT exhibits highly anisotropic and three-dimensional behavior, with a much smaller out-of-plane coherence length than the interlayer distance between FeSe sheets. The authors consider this to be the reason for the robust high-Tc superconductivity of monolayer FeSe.

Anisotropy of the upper critical field and its thickness dependence in superconducting FeSe electric-double-layer transistors

Phys. Rev. B 97, 174520 (2018) - Published 29 May, 2018

High-temperature superconductivity in FeSe thin films has attracted keen interest owing to the counterintuitive enhancement of the superconducting critical parameters in the monolayer-thin limit. Here, the authors apply an electrochemical etching technique to the FeSe-based electric-double-layer transistor (FeSe-EDLT) to investigate systematically the thickness and angular dependence of the upper critical magnetic field (Hc2) below 10 nm. Compared with the isotropic Hc2 in low-Tc bulk FeSe, the high-Tc FeSe-EDLT exhibits highly anisotropic and three-dimensional behavior, with a much smaller out-of-plane coherence length than the interlayer distance between FeSe sheets. The authors consider this to be the reason for the robust high-Tc superconductivity of monolayer FeSe.
