Signatures of the Correlated‐Hopping Interaction in Non‐Linear Transport Through a Quantum Dot
Annalen der Physik, EarlyView.Non‐linear thermoelectric transport through a quantum dot is studied, in order to elucidate the signatures of so‐called correlated hopping. The line shapes of the differential conductance and the Seebeck coefficient as functions of gate voltage are clear indicators of this important interaction term.

Computational Discovery of a Novel Yttrium Silicide as an Ambient Pressure Superconductor
Annalen der Physik, EarlyView.We predict a tetragonal YSi₆ whose dumbbell‐silicon network strengthens electron‐phonon coupling, yielding a record 8.4 K critical temperature for binary yttrium silicides. The finding broadens silicide superconductivity design space and spotlights YSi₆ as a candidate material for quantum‐circuit and qubit technologies.

Enhancing Signal Purity in Josephson Structure Measurements
Advanced Physics Research, EarlyView.A low‐noise signal measurement system for dilution refrigerators is presented, combining multistage cryogenic filtering and electromagnetic shielding to suppress broad‐spectrum noise. The setup enables sub‐nanoampere switching current measurements in Josephson junctions, surpassing commercial systems.

Advanced Physics Research, EarlyView.First‐principles calculations demonstrate that the Re1‐xSrxNiO2/Ti3C2 heterostructure exhibits metallic characteristics, with concurrent enhancement in both electronic conductivity and ionic mobility. Machine learning analysis further reveals that strain, lattice parameters and Sr doping concentration critically influence the conductivity.

Advanced Physics Research, EarlyView.The superconducting (SC) transition temperature (TC) increases exponentially to a maximum as the SC coupling parameter increases for both intra‐ and inter‐band interactions. Strong electron–electron interaction within the hole intra‐band leads to the maximum TC.
