Eigenvector continuation with subspace learning
, 2018 A common challenge faced in quantum physics is finding the extremal eigenvalues and eigenvectors of a Hamiltonian matrix in a vector space so large that linear algebra operations on general vectors are not possible.

Understanding Decoherence of the Boron Vacancy Center in Hexagonal Boron Nitride
Advanced Functional Materials, EarlyView.State‐of‐the‐art computations unravel the intricate decoherence dynamics of the boron vacancy center in hexagonal boron nitride across magnetic fields from 0 to 3 T. Five distinct regimes emerge, dominated by nuclear spin interactions, revealing optimal coherence times of 1–20 µs in the 180–350 mT range for isotopically pure samples.

Advanced Functional Materials, EarlyView.A microfluidic system enables the rapid, room‐temperature fabrication of channel‐rich Pd‐Cu alloy nanodendrites with tunable composition, uniform morphology, and finely branched internal structures. The resulting catalysts exhibit over 90% formate selectivity across a broad potential window, along with excellent CO tolerance and enhanced long‐term ...

Decoupling dipolar interactions in dense spin ensembles
Physical Review ResearchDense spin ensembles in solids present a natural platform for studying quantum many-body dynamics. Multiple-pulse coherent control can be used to manipulate the magnetic dipolar interaction between the spins to engineer their dynamics.

A Graph Theory Approach for Regional Controllability of Boolean Cellular Automata
, 2019 Controllability is one of the central concepts of modern control theory that allows a good understanding of a system's behaviour. It consists in constraining a system to reach the desired state from an initial state within a given time interval. When the

Advanced Functional Materials, EarlyView.In this paper, the first use of a siloxane‐substituted silicon phthalocyanine (iso(Si3O)2SiPc) in OTFTs is reported. Moreover, this compound displays the highest hole mobility (exceeding 1 cm2 V−1 s−1) ever recorded for SiPc, and the GIWAXS study reveals thin films with an exceptionally uniform crystalline texture.
