Physical review letters

Ries MG, Wenz AN, Zürn G, Bayha L, Boettcher I, Kedar D, Murthy PA, Neidig M, Lompe T, Jochim S.
PMID: 26196783
Phys Rev Lett. 2015 Jun 12;114(23):230401. doi: 10.1103/PhysRevLett.114.230401. Epub 2015 Jun 08.

The condensation of fermion pairs lies at the heart of superfluidity. However, for strongly correlated systems with reduced dimensionality the mechanisms of pairing and condensation are still not fully understood. In our experiment we use ultracold atoms as a...

Na2TeS3, Na2TeSe3-mP24, and Na2TeSe3-mC48: Crystal Structures and Optical and Electrical Properties of Sodium Chalcogenidotellurates(IV).

Inorganic chemistry

Pompe C, Preitschaft C, Weihrich R, Pfitzner A.
PMID: 26600068
Inorg Chem. 2015 Dec 07;54(23):11457-64. doi: 10.1021/acs.inorgchem.5b02105. Epub 2015 Nov 24.

Pure samples of Na2TeS3 and Na2TeSe3 were synthesized by the reactions of stoichiometric amounts of the elements Na, Te, and Q (Q = S, Se) in the ratio 2:1:3. Both compounds are highly air- and moisture-sensitive. The crystal structures...

Quantum-gas microscope for fermionic atoms.

Physical review letters

Cheuk LW, Nichols MA, Okan M, Gersdorf T, Ramasesh VV, Bakr WS, Lompe T, Zwierlein MW.
PMID: 26024169
Phys Rev Lett. 2015 May 15;114(19):193001. doi: 10.1103/PhysRevLett.114.193001. Epub 2015 May 13.

We realize a quantum-gas microscope for fermionic ^{40}K atoms trapped in an optical lattice, which allows one to probe strongly correlated fermions at the single-atom level. We combine 3D Raman sideband cooling with high-resolution optics to simultaneously cool and...

Assignment of multiline tungsten-183 NMR spectra of diamagnetic polyoxotungstates from intensity patterns.

Inorganic chemistry

Sveshnikov NN, Pope MT.
PMID: 11229582
Inorg Chem. 2000 Feb 07;39(3):591-4. doi: 10.1021/ic9908928.

Measurement of relative integrated intensities and peak heights of multiline one-dimensional 183W NMR spectra of diamagnetic polyoxotungstates can result in complete or partial assignment of chemical shifts, even when 183W-183W spin-coupled satellites are not detectable or well-resolved. The intensity...

Initial nucleation of platinum clusters after reduction of K(2)PtCl(4) in aqueous solution: a first principles study.

Journal of the American Chemical Society

Colombi Ciacchi L, Pompe W, De Vita A.
PMID: 11472168
J Am Chem Soc. 2001 Aug 01;123(30):7371-80. doi: 10.1021/ja002977+.

The initial nucleation of platinum clusters after the reduction of K(2)PtCl(4) in aqueous solution is studied by means of first principles molecular dynamics simulations. A reaction mechanism leading to a Pt dimer is revealed both by gas-phase simulations and...

Permutation entropy: a natural complexity measure for time series.

Physical review letters

Bandt C, Pompe B.
PMID: 12005759
Phys Rev Lett. 2002 Apr 29;88(17):174102. doi: 10.1103/PhysRevLett.88.174102. Epub 2002 Apr 11.

We introduce complexity parameters for time series based on comparison of neighboring values. The definition directly applies to arbitrary real-world data. For some well-known chaotic dynamical systems it is shown that our complexity behaves similar to Lyapunov exponents, and...

Tetrakis(dimethyltin)-containing tungstophosphate [{Sn(CH3)2}4(H2P4W24O92)2]28-: first evidence for a lacunary Preyssler ion.

Inorganic chemistry

Hussain F, Kortz U, Keita B, Nadjo L, Pope MT.
PMID: 16411712
Inorg Chem. 2006 Jan 23;45(2):761-6. doi: 10.1021/ic051990y.

We demonstrate for the first time that the superlacunary polyanion [H(2)P(4)W(24)O(94)](22)(-) reacts with electrophiles. One-pot reaction of this precursor polyanion with dimethyltin dichloride in aqueous acidic medium results in the hybrid organic-inorganic [{Sn(CH(3))(2)}(4)(H(2)P(4)W(24)O(92))(2)](28)(-) (1). Single-crystal X-ray analysis was carried...

Adaptive optical phase estimation using time-symmetric quantum smoothing.

Physical review letters

Wheatley TA, Berry DW, Yonezawa H, Nakane D, Arao H, Pope DT, Ralph TC, Wiseman HM, Furusawa A, Huntington EH.
PMID: 20366982
Phys Rev Lett. 2010 Mar 05;104(9):093601. doi: 10.1103/PhysRevLett.104.093601. Epub 2010 Mar 03.

Quantum parameter estimation has many applications, from gravitational wave detection to quantum key distribution. The most commonly used technique for this type of estimation is quantum filtering, using only past observations. We present the first experimental demonstration of quantum...

A small cavity with reactive internal shell atoms spanned by four {As(W/V)9}-type building blocks allows host-guest chemistry under confined conditions.

The reaction of [H2As(III)W18O60]7- with VO2+ and SO4(2-) ions in aqueous solution leads to a V(IV)/V(V) mixed-valence cluster anion containing the {As4M40O140}-type cryptand which has a high formation tendency. An important result is that it exhibits a new type...

182tungsten Mössbauer spectroscopy of heteropolytungstates.

Dalton transactions (Cambridge, England : 2003)

Bochet CG, Draper T, Bocquet B, Pope MT, Williams AF.

Dalton Trans. 2009 Jul 14;(26):5127-31. doi: 10.1039/b904101j. Epub 2009 May 07.

The tungsten-182 Mössbauer spectra of a series of Keggin structure heteropolytungstates, [EW12O40]n- are reported. There is a very considerable variation in quadrupole coupling at the tungsten nucleus indicating considerable asymmetry in the electron distribution for the more electronegative elements...
