Ultra-relativistic nuclear collisions: event shape engineering [PDF]
, 2012 The evolution of the system created in a high energy nuclear collision is very sensitive to the fluctuations in the initial geometry of the system. In this letter we show how one can utilize these large fluctuations to select events corresponding to a specific initial shape. Such an "event shape engineering" opens many new possibilities in quantitative

Isotopically engineered silicon/silicon-germanium nanostructures as basic elements for a nuclear spin quantum computer [PDF]
, 2001 The idea of quantum computation is the most promising recent developments in the high-tech domain, while experimental realization of a quantum computer poses a formidable challenge. Among the proposed models especially attractive are semiconductor based nuclear spin quantum computer's (S-NSQC), where nuclear spins are used as quantum bistable elements,

Bertini intra-nuclear cascade implementation in Geant4 [PDF]
arXiv, 2003 We present here a intra-nuclear cascade model implemented in Geant4 5.0. The cascade model is based on re-engineering of INUCL code. Models included are Bertini intra-nuclear cascade model with exitons, pre-equilibrium model, nucleus explosion model, fission model, and evaporation model.

Comparison of the PLTEMP code flow instability predictions with measurements made with electrically heated channels for the advanced test reactor. [PDF]
, 2011 When the University of Missouri Research Reactor (MURR) was designed in the 1960s the potential for fuel element burnout by a phenomenon referred to at that time as 'autocatalytic vapor binding' was of serious concern.

Suppression of Pulsed Dynamic Nuclear Polarization by Many-Body Spin Dynamics [PDF]
Phys. Rev. Lett. 132, 106904 (2024), 2023 We study a mechanism by which nuclear hyperpolarization due to the polarization transfer from a microwave-pulse-controlled electron spin is suppressed. From analytical and numerical calculations of the unitary dynamics of multiple nuclear spins, we uncover that, combined with the formation of the dark state within a cluster of nuclei, coherent higher ...
