Why Compressed Hydrides Are Near‐Room‐Temperature Superconductors

open access: yesAnnalen der Physik, Volume 538, Issue 1, January 2026.
A constant magnitude surface with vector directions indicated of the non‐rigid electronic potential of one displaced lithium atom in a Li crystal. The upper figure is of the calculated gauge‐dependent field, the bottom gives its rotation (curl operator) of the physical field that describes amplitude shift from the front of the displaced atom to behind ...

On the Noisy Road to Open Quantum Dynamics: The Place of Stochastic Hamiltonians

open access: yesAnnalen der Physik, Volume 538, Issue 1, January 2026.
Stochastic Hamiltonian formulations of open quantum dynamics are revisited, highlighting their roots in stochastic calculus. The connections among stochastic Hamiltonians, stochastic Schrödinger equations, and master‐equation approaches are made explicit.

Quantum Spin Liquids Stabilized by Disorder in Non‐Kramers Pyrochlores

open access: yesAnnalen der Physik, Volume 538, Issue 1, January 2026.
This study explores how random structural disorder induces a quantum spin‐liquid phase in non‐Kramers pyrochlore oxides. Using a real‐space gauge mean‐field approach to the random transverse‐field Ising model, we demonstrate that the quantum spin ice appears and remains remarkably robust against disorder, with only a narrow Griffiths region near the ...

Nonadiabatic and Anharmonic Effects in High‐Pressure H3S and D3S Superconductors

open access: yesAnnalen der Physik, Volume 538, Issue 1, January 2026.
Superconductivity in high‐pressure H3S${\rm H}_3{\rm S}$ and D3S${\rm D}_3{\rm S}$ is studied using first‐principles calculations that include anharmonic lattice dynamics and nonadiabatic electron‐phonon vertex corrections, going beyond the conventional Migdal‐Eliashberg framework. These effects suppress the effective electron–phonon coupling and lower
