Ultimate Precision Limits for Noisy Frequency Estimation.

Physical review letters

Smirne A, Kołodyński J, Huelga SF, Demkowicz-Dobrzański R.
PMID: 27058065
Phys Rev Lett. 2016 Mar 25;116(12):120801. doi: 10.1103/PhysRevLett.116.120801. Epub 2016 Mar 24.

Quantum metrology protocols allow us to surpass precision limits typical to classical statistics. However, in recent years, no-go theorems have been formulated, which state that typical forms of uncorrelated noise can constrain the quantum enhancement to a constant factor...

Bloch-Redfield equations for modeling light-harvesting complexes.

The Journal of chemical physics

Jeske J, Ing DJ, Plenio MB, Huelga SF, Cole JH.
PMID: 25681884
J Chem Phys. 2015 Feb 14;142(6):064104. doi: 10.1063/1.4907370.

We challenge the misconception that Bloch-Redfield equations are a less powerful tool than phenomenological Lindblad equations for modeling exciton transport in photosynthetic complexes. This view predominantly originates from an indiscriminate use of the secular approximation. We provide a detailed...

Wavelet analysis of molecular dynamics: efficient extraction of time-frequency information in ultrafast optical processes.

The Journal of chemical physics

Prior J, Castro E, Chin AW, Almeida J, Huelga SF, Plenio MB.
PMID: 24329052
J Chem Phys. 2013 Dec 14;139(22):224103. doi: 10.1063/1.4837718.

New experimental techniques based on nonlinear ultrafast spectroscopies have been developed over the last few years, and have been demonstrated to provide powerful probes of quantum dynamics in different types of molecular aggregates, including both natural and artificial light...

Treatment referral system for tuberculosis patients in Dhaka, Bangladesh.

Public health action

Islam S, Hirayama T, Islam A, Ishikawa N, Afsana K.
PMID: 26767176
Public Health Action. 2015 Dec 21;5(4):236-40. doi: 10.5588/pha.15.0052.

OBJECTIVE: To evaluate the referral system in an urban DOTS-based programme in Dhaka, Bangladesh, including the peri-urban area, and to identify opportunities to strengthen the system.DESIGN: This was a retrospective cohort study in which diagnosed tuberculosis (TB) patients and...

Evaluation of cardioprotective effect of silk cocoon (Abresham) on isoprenaline-induced myocardial infarction in rats.

Avicenna journal of phytomedicine

Srivastav RK, Siddiqui HH, Mahmood T, Ahsan F.
PMID: 25050277
Avicenna J Phytomed. 2013;3(3):216-23.

OBJECTIVE: The study was conducted to evaluate cardioprotective effect of silk cocoon (Abresham) Bombyx mori (B. mori) on isoprenaline-induced myocardial infarction. This study deals with the cocoons, which is called Abresham in the Unani system of medicine. It is...

Robust creation of entanglement between ions in spatially separate cavities.

Physical review letters

Browne DE, Plenio MB, Huelga SF.
PMID: 12935110
Phys Rev Lett. 2003 Aug 08;91(6):067901. doi: 10.1103/PhysRevLett.91.067901. Epub 2003 Aug 04.

We present a protocol that allows the generation of a maximally entangled state between individual atoms held in spatially separate cavities. Assuming perfect detectors and neglecting spontaneous emission from the atoms, the resulting idealized scheme is deterministic. Under more...

Palladium-catalyzed dual C-H or N-H functionalization of unfunctionalized indole derivatives with alkenes and arenes.

Beilstein journal of organic chemistry

Broggini G, Beccalli EM, Fasana A, Gazzola S.
PMID: 23209507
Beilstein J Org Chem. 2012;8:1730-46. doi: 10.3762/bjoc.8.198. Epub 2012 Oct 11.

This review highlights the development of palladium-catalyzed C-H and N-H functionalization reactions involving indole derivatives. These procedures require unactivated starting materials and are respectful of the basic principle of sustainable chemistry tied to atom economy.

Damaging graphene with ozone treatment: a chemically tunable metal-insulator transition.

ACS nano

Leconte N, Moser J, Ordejón P, Tao H, Lherbier A, Bachtold A, Alsina F, Sotomayor Torres CM, Charlier JC, Roche S.
PMID: 20695517
ACS Nano. 2010 Jul 27;4(7):4033-8. doi: 10.1021/nn100537z.

We present a multiscale ab initio study of electronic and transport properties of two-dimensional graphene after epoxide functionalization via ozone treatment. The orbital rehybridization induced by the epoxide groups triggers a strong intervalley scattering and changes dramatically the conduction...

The sub-Ohmic spin-boson model possesses a quantum phase transition at zero temperature between a localized and a delocalized phase, whose properties have so far only been extracted by numerical approaches. Here we present an extension of the Silbey-Harris variational...
