Time-continuous Bell measurements.

Physical review letters

Hofer SG, Vasilyev DV, Aspelmeyer M, Hammerer K.
PMID: 24206465
Phys Rev Lett. 2013 Oct 25;111(17):170404. doi: 10.1103/PhysRevLett.111.170404. Epub 2013 Oct 22.

We combine the concept of Bell measurements, in which two systems are projected into a maximally entangled state, with the concept of continuous measurements, which concerns the evolution of a continuously monitored quantum system. For such time-continuous Bell measurements...

Satisfying the Einstein-Podolsky-Rosen criterion with massive particles.

Nature communications

Peise J, Kruse I, Lange K, Lücke B, Pezzè L, Arlt J, Ertmer W, Hammerer K, Santos L, Smerzi A, Klempt C.
PMID: 26612105
Nat Commun. 2015 Nov 27;6:8984. doi: 10.1038/ncomms9984.

In 1935, Einstein, Podolsky and Rosen (EPR) questioned the completeness of quantum mechanics by devising a quantum state of two massive particles with maximally correlated space and momentum coordinates. The EPR criterion qualifies such continuous-variable entangled states, where a...

Photoneutron cross sections for unstable neutron-rich oxygen isotopes.

Physical review letters

Leistenschneider A, Aumann T, Boretzky K, Cortina D, Cub J, Datta Pramanik U, Dostal W, Elze TW, Emling H, Geissel H, Grünschloss A, Hellstr M, Holzmann R, Ilievski S, Iwasa N, Kaspar M, Kleinböhl A, Kratz JV, Kulessa R, Leifels Y, Lubkiewicz E, Münzenberg G, Reiter P, Rejmund M, Scheidenberger C, Schlegel C, Simon H, Stroth J, Sümmerer K, Wajda E, Walús W, Wan S.
PMID: 11415271
Phys Rev Lett. 2001 Jun 11;86(24):5442-5. doi: 10.1103/PhysRevLett.86.5442.

The dipole response of stable and unstable neutron-rich oxygen nuclei of masses A = 17 to A = 22 has been investigated experimentally utilizing electromagnetic excitation in heavy-ion collisions at beam energies about 600 MeV/nucleon. A kinematically complete measurement...

Strong coupling of a mechanical oscillator and a single atom.

Physical review letters

Hammerer K, Wallquist M, Genes C, Ludwig M, Marquardt F, Treutlein P, Zoller P, Ye J, Kimble HJ.
PMID: 19792563
Phys Rev Lett. 2009 Aug 07;103(6):063005. doi: 10.1103/PhysRevLett.103.063005. Epub 2009 Aug 06.

We propose and analyze a setup to achieve strong coupling between a single trapped atom and a mechanical oscillator. The interaction between the motion of the atom and the mechanical oscillator is mediated by a quantized light field in...

Factors involved in the distribution pattern of ciliates in the water column of a transparent alpine lake.

Journal of plankton research

Sonntag B, Summerer M, Sommaruga R.
PMID: 21984852
J Plankton Res. 2011 Mar;33(3):535-540. doi: 10.1093/plankt/fbq106.

The recurrent depth preference of three ciliate species (two prostomatids and one haptorid) in a transparent alpine lake indicates the existence of niche partitioning among them involving potential factors such as avoidance of high ultraviolet radiation levels and zooplankton...

Study of the 14Be continuum: identification and structure of its second 2+ state.

Physical review letters

Aksyutina Y, Aumann T, Boretzky K, Borge MJ, Caesar C, Chatillon A, Chulkov LV, Cortina-Gil D, Datta Pramanik U, Emling H, Fynbo HO, Geissel H, Heinz A, Ickert G, Johansson HT, Jonson B, Kulessa R, Langer C, LeBleis T, Mahata K, Münzenberg G, Nilsson T, Nyman G, Palit R, Paschalis S, Prokopowicz W, Reifarth R, Rossi D, Richter A, Riisager K, Schrieder G, Simon H, Sümmerer K, Tengblad O, Thies R, Weick H, Zhukov MV.
PMID: 24483646
Phys Rev Lett. 2013 Dec 13;111(24):242501. doi: 10.1103/PhysRevLett.111.242501. Epub 2013 Dec 09.

The coupling between bound quantum states and those in the continuum is of high theoretical interest. Experimental studies of bound drip-line nuclei provide ideal testing grounds for such investigations since they, due to the feeble binding energy of their...

Quantum signatures of the optomechanical instability.

Physical review letters

Qian J, Clerk AA, Hammerer K, Marquardt F.
PMID: 23368459
Phys Rev Lett. 2012 Dec 21;109(25):253601. doi: 10.1103/PhysRevLett.109.253601. Epub 2012 Dec 18.

In the past few years, coupling strengths between light and mechanical motion in optomechanical setups have improved by orders of magnitude. Here we show that, in the standard setup under continuous laser illumination, the steady state of the mechanical...
