2k_{F} density wave instability of composite Fermi liquid

Physical Review Research, 2020
We investigate the 2k_{F} density wave instability of non-Fermi-liquid states by combining exact diagonalization with renormalization group analysis. At the half-filled zeroth Landau level, we study the fate of the composite Fermi liquid in the presence ...

Multidimensional Bosonization

, 2000
Bosonization of degenerate fermions yields insight both into Landau Fermi liquids, and into non-Fermi liquids. We begin our review with a pedagogical introduction to bosonization, emphasizing its applicability in spatial dimensions greater than one ...

FERMI AND NON-FERMI LIQUID BEHAVIOR OF THE MULTICHANNEL RESONANT-LEVEL MODEL

Acta Physica Sinica, 1996
In this paper we have transformed the three-dimensional multichannel resonant-level model into one-dimensional model using ths s-wave scattering approximation, and then map it onto a single channel Kondo model at the operator level by use of a bosonization technique.

1D Light‐Emitting MAPbBr3 Perovskite Encapsulated in Carbon Nanotubes

Advanced Functional Materials, EarlyView.
Encapsulation of MAPbBr3 perovskite in single‐walled carbon nanotubes (SWCNTs) yields a hybrid nanomaterial with distinctive optoelectronic properties. Perovskite confinement induces a unified single‐peak photoluminescence (PL) with a reduced lifetime, while charge transfer alters the optical properties of nanotubes.

Engineering Active CeO2/Fe3C Interfacial Sites to Generate High‐Charge‐Density Fe for Enhanced Oxygen Reduction Reaction Efficiency

Advanced Functional Materials, EarlyView.
A well‐modulated CeO2/Fe3C heterostructure is successfully constructed. The electron redistribution induced by CeO2 not only enhances the formation energy of Fe vacancies and hinders the dissolution of Fe but also reduces the energy barrier of the ORR.

Mechanism of Fermi Level Pinning at Metal/Germanium Interfaces

, 2011
The physical origin of Fermi level pinning (FLP) at metal/Ge interfaces has been argued over a long period. Using the Fe$_{3}$Si/Ge(111) heterostructure developed originally, we can explore electrical transport properties through atomically matched metal/

Built‐In Electric Field in 2D/2D LDH/Antimonene Heterostructure to Induce Stable β‐NiOOH at Ultralow Potential for Cost‐Effective Water Electrolysis

Advanced Functional Materials, EarlyView.
In this paper, a built‐in electric field (BEF) strategy is proposed to fabricate NiFe‐LDH/antimonene heterostructure as bifunctional electrocatalysts for oxygen evolution reaction (OER) and hydrogen evolution reaction (HER). The formed BEF generates a local potential that reduces the potential for the formation of β‐NiOOH, thereby enabling ultra‐low ...

Angle-resolved photoemission spectroscopy of Co-based boride superconductor LaCo1.73Fe0.27B2

, 2012
We have performed angle-resolved photoemission spectroscopy of Co-based boride superconductor LaCo1.73Fe0.27B2 (Tc = 4.1 K), which is isostructural to the 122-type Fe-pnictide superconductor with the pnictogen atom being replaced with boron.
