Superconductor-to-metal transition in overdoped cuprates

期刊: NPJ QUANTUM MATERIALS, 2021; 6 (1)

We present a theoretical framework for understanding the behavior of the normal and superconducting states of overdoped cuprate high temperature super......

Coexistence of ferromagnetism, antiferromagnetism, and superconductivity in magnetically anisotropic (Eu,La)FeAs2

期刊: NPJ QUANTUM MATERIALS, 2021; 6 (1)

Materials with exceptional magnetism and superconductivity usually conceive emergent physical phenomena. Here, we investigate the physical properties ......

Negative thermal expansion in YbMn2Ge2 induced by the dual effect of magnetism and valence transition

期刊: NPJ QUANTUM MATERIALS, 2021; 6 (1)

Negative thermal expansion (NTE) is an intriguing property, which is generally triggered by a single NTE mechanism. In this work, an enhanced NTE (alp......

High-energy magnetic excitations from heavy quasiparticles in CeCu2Si2

期刊: NPJ QUANTUM MATERIALS, 2021; 6 (1)

Magnetic fluctuations is the leading candidate for pairing in cuprate, iron-based, and heavy fermion superconductors. This view is challenged by the r......

Oxygen vacancy-induced topological nanodomains in ultrathin ferroelectric films

期刊: NPJ QUANTUM MATERIALS, 2021; 6 (1)

Oxygen vacancy in oxide ferroelectrics can be strongly coupled to the polar order via local strain and electric fields, thus holding the capability of......

Metal-insulator-like transition, superconducting dome and topological electronic structure in Ga-doped Re3Ge7

期刊: NPJ QUANTUM MATERIALS, 2021; 6 (1)

Superconductivity frequently appears by doping compounds that show a collective phase transition. So far, however, this has not been observed in topol......

Topological phase transition and single/multi anyon dynamics of Z(2) spin liquid

期刊: NPJ QUANTUM MATERIALS, 2021; 6 (1)

Among the quantum many-body models that host anyon excitation and topological orders, quantum dimer models (QDM) provide a suitable playground for stu......

Gapless quantum spin liquid in a honeycomb Gamma magnet

期刊: NPJ QUANTUM MATERIALS, 2021; 6 (1)

A family of spin-orbit coupled honeycomb Mott insulators offers a playground to search for quantum spin liquids (QSLs) via bond-dependent interactions......

Multiple quantum phase transitions of different nature in the topological kagome magnet Co3Sn2-xInxS2

期刊: NPJ QUANTUM MATERIALS, 2021; 6 (1)

The exploration of topological electronic phases that result from strong electronic correlations is a frontier in condensed matter physics. One class ......

Periodically modulated skyrmion strings in Cu2OSeO3

期刊: NPJ QUANTUM MATERIALS, 2021; 6 (1)

Magnetic skyrmions are vortex-like spin textures, which are usually treated as two-dimensional objects. In their lattice state, they form well-ordered......

Spin dynamics and Griffiths singularity in the random quantum Ising magnet PrTiNbO6

期刊: NPJ QUANTUM MATERIALS, 2021; 6 (1)

In crystalline magnets, interaction randomness is usually thought as a negative factor preventing interesting quantum phenomena to occur. However, int......

Straintronics with van der Waals materials

With the outstanding mechanical properties, van der Waals (vdW) materials have attracted extensive attention in the research of straintronics in the p......

Giant linear magnetoresistance in half-metallic Sr2CrMoO6 thin films

期刊: NPJ QUANTUM MATERIALS, 2021; 6 (1)

Linear magnetoresistance (LMR) is a special case of a magnetic-field induced resistivity response, which has been reported in highly disordered semico......

Imaging the formation and surface phase separation of the CE phase

期刊: NPJ QUANTUM MATERIALS, 2021; 6 (1)

The CE phase is an extraordinary phase exhibiting the simultaneous spin, charge, and orbital ordering due to strong electron correlation. It is an ide......

Spin photogalvanic effect in two-dimensional collinear antiferromagnets

期刊: NPJ QUANTUM MATERIALS, 2021; 6 (1)

Recent discovered two-dimensional (2D) antiferromagnetic (AFM) van der Waals quantum materials have attracted increasing interest due to the emergent ......
