Semiconductor qubits in practice

A Chatterjee, P Stevenson, S De Franceschi… - Nature Reviews …, 2021 - nature.com
In the past decade, semiconducting qubits have made great strides in overcoming decoherence,
improving the prospects for scalability and have become one of the leading contenders …

Effector CD4+ and CD8+ T‐cell mechanisms in the control of respiratory virus infections

…, RD Cardin, JW Brooks, PG Stevenson - Immunological …, 1997 - Wiley Online Library
The rules for T‐cell‐mediated control of viruses that infect via the respiratory mucosae show
both common themes and differences depending on the nature of the pathogen. Virus‐…

Plant secondary metabolites in nectar: impacts on pollinators and ecological functions

PC Stevenson, SW Nicolson, GA Wright - Functional Ecology, 2017 - Wiley Online Library
The ecological function of secondary metabolites in plant defence against herbivores is well
established, but their role in plant–pollinator interactions is less obvious. Nectar is the major …

Optimized perturbation theory

PM Stevenson - Physical Review D, 1981 - APS
Conventional perturbation theory gives different results in different renormalization schemes,
a problem which is especially serious in quantum chromodynamics (QCD). I propose a …

A study of the nucleation and growth processes in the synthesis of colloidal gold

J Turkevich, PC Stevenson, J Hillier - Discussions of the faraday …, 1951 - pubs.rsc.org
After a preliminary survey with the electron microscope of various preparations of colloidal
gold, a study was made of the process of nucleation and growth in gold colloids. It was shown …

Gaussian effective potential. II. λ field theory

PM Stevenson - Physical Review D, 1985 - APS
… We write the field P as Pp+P, where Pp is a constant classical field, and P is a quantum
free field of mass Q: The state 10)n& is then thevacuum state of this free field. The required …

Persistent effects of pre-Columbian plant domestication on Amazonian forest composition

…, JF Duivenvoorden, PVA Fine, PR Stevenson… - Science, 2017 - science.org
The extent to which pre-Columbian societies altered Amazonian landscapes is hotly debated.
We performed a basin-wide analysis of pre-Columbian impacts on Amazonian forests by …

Skyrme interaction and nuclear matter constraints

…, JSS Martins, A Delfino, JR Stone, PD Stevenson - Physical Review C, 2012 - APS
This paper presents a detailed assessment of the ability of the 240 Skyrme interaction parameter
sets in the literature to satisfy a series of criteria derived from macroscopic properties of …

The sense in which a" weak measurement" of a spin-˝ particle's spin component yields a value 100

IM Duck, PM Stevenson, ECG Sudarshan - Physical Review D, 1989 - APS
… wave function P;„(p) is a Gaussian centered on p =0 with width bp. The q-representation
wave function P;„(q), which is the Fourier transform of P;„(p), would alsobe of Gaussian form. …

The formation of colloidal gold

J Turkevich, PC Stevenson, J Hillier - The Journal of Physical …, 1953 - ACS Publications
An electron microscope study has been made of the process of reduction of gold chloride to
colloidal gold. A method was found of producing gold of uniform size in the diameter range …
