Two Ising-like magnetic excitations in a single-layer cuprate superconductor [PDF]

open access: yes, 2012
There exists increasing evidence that the phase diagram of the high-transition temperature (Tc) cuprate superconductors is controlled by a quantum critical point.

Synthesis and Electronic Structure Modulation of 2D MBenes for Conversion of Nitrates Into Green Ammonia

open access: yesSmall Structures, Volume 7, Issue 3, March 2026.
Two‐dimensional transition metal boride‐based materials as electrocatalysts for nitrate reduction reaction (NO3RR). It covers the synthesis and structure of Mbenes for electrocatalytic nitrate reduction reaction (NO3RR) to ammonia, including ammonia detection methods, following the future perspectives.

Pseudogap temperature as a Widom line in doped Mott insulators

open access: yes, 2012
The pseudogap refers to an enigmatic state of matter with unusual physical properties found below a characteristic temperature $T^*$ in hole-doped high-temperature superconductors. Determining $T^*$ is critical for understanding this state. Here we study

Non-universal pairing symmetry and pseudogap phenomena in hole- and electron-doped cuprate superconductors [PDF]

open access: yes, 2003
Experimental studies of the pairing state of cuprate superconductors reveal asymmetric behaviors of the hole-doped (p-type) and electron-doped (n-type) cuprates.

Thermal Transport Properties of W2TMB2 Solid Solutions (TM = Fe, Co, Ni)

open access: yesZeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 3, 25 February 2026.
Thermal transport properties of W2TMB2 (TM: Fe, Co, Ni) and their solid solutions, as well as electron backscatter diffraction measurements, show interesting particularities depending on the TM type and content. In this work, thermal transport properties of W2FexCo1‐xB2, W2FexNi1-xCoB2, and W2NixCo1‐xB2 (x: 0.0, 0.2, 0.4, 0.6, 0.8, 1.0) were ...

Low-temperature pseudogap phenomenon: precursor of high-Tc superconductivity

open access: yesNew Journal of Physics, 2014
In this paper, we try to understand the pseudogap phenomenon observed in the cuprate superconductor through a model study. Specifically, we explore the so-called low-temperature pseudogap state by turning off the superconducting (SC) off diagonal long ...

Unambiguous connection between the Fermi surface topology and the pseudogap in Bi$_{2}$Sr$_2$CaCu$_2$O$_{8+d}$

open access: yes, 2018
We study the behavior of the pseudogap in overdoped Bi$_{2}$Sr$_2$CaCu$_2$O$_{8+d}$ by electronic Raman scattering (ERS) and angle-resolved photoemission spectroscopy (ARPES) on the same single crystals.

Phase fluctuations and pseudogap phenomena [PDF]

open access: yesPhysics Reports, 2001
This article reviews the current status of precursor superconducting phase fluctuations as a possible mechanism for pseudogap formation in high-temperature superconductors. In particular we compare this approach which relies on the two-dimensional nature of the superconductivity to the often used $T$-matrix approach.

Hidden Charge‐Order in the Mixed‐Valent K0.75Li2Cr6O12 High‐Pressure Oxide

open access: yesAdvanced Science, Volume 13, Issue 11, 23 February 2026.
K0.75Li2Cr6O12 is one of the few mixed valent chromium oxides. It shows a single angle spiral magnetic structure with a k = [1/3 1/3 ¼] propagation vector. Density functional theory reveals a hidden charge order that is necessary to stabilize the antiferromagnetic (AFM) ground state.

Structural Phase Separation and Enhanced Superconductivity in La1.875Ba0.125CuO4 Under Uniaxial Strain

open access: yesAdvanced Materials, Volume 38, Issue 2, 8 January 2026.
Uniaxial strain is used to tune electronic, structural, and magnetic order in a copper oxide superconductor. Application of a moderate uniaxial strain condition across the low‐temperature orthorhombic‐to‐tetragonal transition creates a condition that disrupts the usual stripe ordering.
