Resource-optimized fault-tolerant simulation of the Fermi-Hubbard model and high-temperature superconductor models

npj Quantum Information
Exploring low-cost applications is paramount to creating value in early fault-tolerant quantum computers. Here, we optimize both gate and qubit counts of recent algorithms for simulating the Fermi-Hubbard model.

Interface Engineering Remarkably Improves the Stability of Fe‐Based Electrode for Alkaline Water Electrolysis at Industrial Ampere‐Level Current Density

Carbon Energy, EarlyView.
Interface engineering improves the stability of iron‐based industrial oxygen evolution catalysts by more than 2000 times at ampere‐level current density. ABSTRACT Iron‐based self‐supported electrocatalysts offer cost‐effective oxygen evolution activity but suffer from severe stability degradation under industrial operation.

Superconductivity in strongly correlated electronic systems

Moldavian Journal of the Physical Sciences, 2009
A microscopic theory of superconducting pairing within the Hubbard model is discussed. A Dyson equation for the matrix thermodynamic Green function in the Nambu representation for Hubbard operators is derived by applying the Mori-type projection ...

Direct Capture of Dynamic Surface Reconstruction in a Perovskite Cathode via Operando Raman Spectroscopy

Carbon Energy, EarlyView.
Operando Raman spectroscopy directly captures the dynamic form conditions of the BaCoO3‐δ phase on the BSCY surface. This observation provides critical insight into the phase evolution mechanisms, which are essential for optimizing the performance and stability of BSCY‐based protonic ceramic fuel cell cathodes.

The Impacts of Chief Sustainability Officers' Structural Power on Corporate Social Responsibility Performance

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Extant literature assumes that powerful executives can wield their influence with minimal opposition from lower‐power actors. We reconsider this assumption by incorporating the coalitional view in which lower‐power actors can mobilize coalitions to resist.
