“…These questions will be addressed in separate communications [88,89] devoted to stochastic modelling of excitation function fluctuations in DHIC. Care should be taken in approaching this problem since spin and parity correlation between S-matrix residues is of order D/β D/Γ → 0.…”

“…Indeed, clustering has been shown to be very important theoretically in low-energy [25] and high energy heavy-ion collisions [26,27]. Moreover, there exists some experimental evidence, as well as quite a few theoretical predictions, for the presence of nuclear molecular states in light and medium-mass nuclei at high excitation energy [28][29][30][31][32][33].…”

Background: Modern applications of nuclear time-dependent density functional theory (TDDFT) are often capable of providing quantitative description of heavy ion reactions. However, the structure of pre-compound (pre-equilibrium, pre-fission) states produced in heavy ion reactions are difficult to assess theoretically in TDDFT as the single-particle density alone is a weak indicator of shell structure and cluster states.Purpose: We employ the time-dependent nucleon localization function (NLF) to reveal the structure of precompound states in nuclear reactions involving light and medium-mass ions. We primarily focus on spin saturated systems with N = Z. Furthermore, we study reactions with oxygen and carbon ions, for which some experimental evidence for α clustering in pre-compound states exists. O + 12 C, we showed that the pre-compound system has a tendency to form α clusters. This result supports the experimental findings that the presence of cluster structures in the projectile and target nuclei gives rise to strong entrance channel effects and enhanced α emission. Conclusion:The time-dependent nucleon localization measure is a very good indicator of clusters structures in complex pre-compound states formed in heavy-ion fusion reactions. The localization reveals the presence of collective vibrations involving cluster structures, which dominate the initial dynamics of the fusing system.

“…Note that the total spin and parity off-diagonal S-matrix correlations for evaporation processes were justified in [12] in the limit N eff → ∞. For the cross symmetry phase relaxation time much longer than the energy relaxation time, the formalism also leads to (i) quantum-classical transition [24,25], stable coherent rotation [26,27,28], Schrödinger cat states [29,30] in complex collisions in the regime of strongly overlapping resonances of the intermediate system, and (ii) spontaneous correlations, non-equilibrium phase transitions [31] and anomalous sensitivity in finite highly excited many-body systems [32].…”

Abstract. Thermalization in highly excited quantum many-body system does not necessarily mean a complete memory loss of the way the system was formed. This effect may pave a way for a quantum computing, with a large number of qubits n 100-1000, far beyond the quantum chaos border. One of the manifestations of such a thermalized nonequilibrated matter is revealed by a strong asymmetry around 90• c.m. of evaporating proton yield in the Bi(γ,p) photonuclear reaction. The effect is described in terms of anomalously slow cross symmetry phase relaxation in highly excited quantum many-body systems with exponentially large Hilbert space dimensions. In the above reaction this phase relaxation is about eight orders of magnitude slower than energy relaxation (thermalization).
