Ultrafast Terahertz Dynamics in Hybrid Van der Waals Superconductor‐Topological Insulator Metamaterials

Advanced Photonics Research, Volume 7, Issue 4, April 2026.
Hybrid van der Waals topological–superconducting heterostructures enable cryogenically compatible, highly tunable THz photonic circuits. We model ultrafast THz modulation in proximitized (Bi2‐xInx)Se3–BSCCO devices, capturing indium‐driven topological phase transitions and ultrafast superconductor dynamics.

Superconductivity of QCD vacuum in strong magnetic field

, 2010
We show that in a sufficiently strong magnetic field the QCD vacuum may undergo a transition to a new phase where charged $\rho^\pm$ mesons are condensed.

Transmission of Radio‐Frequency Waves and Nuclear Magnetic Resonance in Lanthanum Superhydrides

Advanced Science, Volume 13, Issue 23, 23 April 2026.
1H NMR and radio‐frequency transmission measurements of lanthanum superhydrides at 165 GPa reveals a transition at 260–280 K by a strong suppression of the signal intensity, significant changes in NMR spectra, including a dramatic decrease of the relaxation rate 1/T1T, and pronounced shielding effect, which may have a superconducting nature.

Key pairing interaction in layered doped ionic insulators

, 2010
A controversial issue on whether the electron-phonon interaction (EPI) is crucial for high-temperature superconductivity or it is weak and inessential has remained one of the most challenging problems of contemporary condensed matter physics. We employ a

Scattering and Pairing in Cuprate Superconductors

, 2010
The origin of the exceptionally strong superconductivity of cuprates remains a subject of debate after more than two decades of investigation. Here we follow a new lead: The onset temperature for superconductivity scales with the strength of the ...

Multi-channel exchange-scattering spin polarimetry

, 2015
Electron spin takes critical role in almost all novel phenomena discovered in modern condensed matter physics (High-temperature superconductivity, Kondo effect, Giant Magnetoresistance, topological insulator, quantum anomalous Hall effect, etc.). However,

Evolution of Complexity in Out-of-Equilibrium Systems by Time-Resolved or Space-Resolved Synchrotron Radiation Techniques

, 2019
Out-of-equilibrium phenomena are attracting high interest in physics, materials science, chemistry and life sciences. In this state, the study of structural fluctuations at different length scales in time and space are necessary to achieve significant ...

Electromagnetic superconductivity of vacuum induced by strong magnetic field

, 2012
The quantum vacuum may become an electromagnetic superconductor in the presence of a strong external magnetic field of the order of 10^{16} Tesla. The magnetic field of the required strength (and even stronger) is expected to be generated for a short ...

High Temperature Superconductivity: the explanation

, 2011
Soon after the discovery of the first high temperature superconductor by Georg Bednorz and Alex Mueller in 1986 the late Sir Nevill Mott answering his own question "Is there an explanation?" [Nature v 327 (1987) 185] expressed a view that the Bose ...
