Twist Engineering of Hybrid 2D van der Waals‐Transition Metal Oxide Membranes

Advanced Physics Research, EarlyView.
The integration of transition metal oxide membranes with 2D van der Waals materials offers exciting opportunities to study new interfacial phenomena. These interactions can create complex moiré patterns that change the materials' properties. Understanding these interactions, influenced by symmetry and distortion, poses significant challenges and ...

Superconductivity and other phase transitions in a hybrid Bose-Fermi mixture formed by a polariton condensate and an electron system in two dimensions

, 2015
Interacting Bose-Fermi systems play a central role in condensed matter physics. Here, we analyze a novel Bose-Fermi mixture formed by a cavity exciton-polariton condensate interacting with a two-dimensional electron system.

Supercritical Carbon Dioxide‐Assisted Interface Formation of LaAlO3/SrTiO3 for Room‐Temperature Ferromagnetism

Advanced Physics Research, EarlyView.
This work pioneers a non‐invasive route for strain engineering of quantum states at complex oxide interfaces, making use of supercritical CO2 as a tunable “strain field” to induce room‐temperature ferromagnetism in 3D LaAlO3/SrTiO3 composites. Structural and chemical analyses confirm the magnetism is strictly interfacial and driven by lattice tensile ...

Prediction of Nontrivial Band Topology and Superconductivity in Mg$_2$Pb

, 2017
The interplay of BCS superconductivity and nontrivial band topology is expected to give rise to opportunities for creating topological superconductors, achieved through pairing spin-filtered boundary modes via superconducting proximity effects.

Asymmetry of the Ferroelectric Phase Transition in BaTiO3

Advanced Materials, Volume 38, Issue 25, 4 May 2026.
Phase transitions are typically assumed to behave identically in forward and reverse. This work shows that in the ferroelectric material barium titanate this is not true: heating drives an abrupt, first‐order jump, while cooling gives a smooth, continuous change.

Topological Superconductivity without Proximity Effect

, 2013
Majorana Fermions, strange particles that are their own antiparticles, were predicted in 1937 and have been sought after ever since. In condensed matter they are predicted to exist as vortex core or edge excitations in certain exotic superconductors ...

High‐mobility suspended MoS2 devices with tunable threshold voltage

InfoMat, Volume 8, Issue 5, May 2026.
Due to their atomic‐scale thickness, two‐dimensional materials (2DMs) are highly sensitive to their environment, including the substrate. By fabricating various suspended molybdenum disulfide devices, this study demonstrates that the suspended structure can shield the influence of the substrate on the properties of 2DMs, thereby enabling better ...

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

Advanced Functional Materials, Volume 36, Issue 27, 2 April 2026.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Flat bands in condensed-matter systems – perspective for magnetism and superconductivity

Contemporary Physics
There is a recent upsurge of interests in flat bands in condensed-matter systems and the consequences for magnetism and superconductivity. This article highlights the physics, where peculiar quantum-mechanical mechanisms for the physical properties such as flatband ferromagnetism and flatband superconductivity that arise when the band is not trivially ...
