QCD Phase Diagram at NICA energies: horn effect and light clusters in THESEUS
D. Blaschke, A. V. Friesen, Yu. B. Ivanov +5
We discuss recent progress in the development of the three-fluid hydrodynamics-based program THESEUS towards an event generator suitable for applications to heavy-ion collisions at…
Light cluster production at NICA
N. -U. Bastian, P. Batyuk, D. Blaschke +6
Light cluster production at the NICA accelerator complex offers unique possibilities to use these states as "rare probes" of in-medium characteristics such as phase space occupatio…
Quartic Lattice Interactions, Soliton-like Excitations and Electron Pairing in One-Dimensional Anharmonic Crystals
M. G. Velarde, L. Brizhik, A. P. Chetverikov +3
We show that two added, excess electrons with opposite spins in one-dimensional crystal lattices with quartic anharmonicity may form a bisolectron, which is a localized bound state…
Decoherence in an exactly solvable qubit model with initial qubit-environment correlations
V. G. Morozov, S. Mathey, G. Röpke
We study a model of dephasing (decoherence) in a two-state quantum system (qubit) coupled to a bath of harmonic oscillators. An exact analytic solution for the reduced dynamics of…
BBGKY kinetic approach for an e-e+gamma plasma created from the vacuum in a strong laser-generated electric field: The one-photon annihilation channel
D. B. Blaschke, V. V. Dmitriev, G. Roepke +1
In the present work a closed system of kinetic equations is obtained from the truncation of the BBGKY hierarchy for the description of the vacuum creation of an electron - positron…
Quantum Condensates in Nuclear Matter: Problems
G. Ropke, D. Zablocki
In connection with the contribution "Quantum Condensates in Nuclear Matter" some problems are given to become more familiar with the techniques of many-particle physics.
Unconstrained SU(2) Yang-Mills Theory with Topological Term in the Long-Wavelength Approximation
A. M. Khvedelidze, D. M. Mladenov, H. -P. Pavel +1
The Hamiltonian reduction of SU(2) Yang-Mills theory for an arbitrary θangle to an unconstrained nonlocal theory of a self-interacting positive definite symmetric 3 \times 3 matrix…

A. M. Khvedelidze, D. M. Mladenov, H. -P. Pavel +1
The Hamiltonian reduction of classical SU(2) Yang-Mills field theory to the equivalent unconstrained theory of gauge invariant local dynamical variables is generalized to the case…
Two-particle properties in nuclear matter at finite temperatures
G. Roepke, A. Schnell
Correlation effects in nuclear matter at finite temperatures are studied for subnuclear densities () and medium excitation energy, where a nonrelativistic potential approach…
Non-Markovian effects in strong-field pair creation
S. Schmidt, D. Blaschke, G. Ropke +3
We analyze a quantum kinetic equation describing both boson and fermion pair production and explore analytically and numerically the solution of the non-Markovian kinetic equation.…
Four-particle condensate in strongly coupled fermion systems
G. Roepke, A. Schnell, P. Schuck +1
Four-particle correlations in fermion systems at finite temperatures are investigated with special attention to the formation of a condensate. Instead of the instability of the nor…
Medium modification of two-particle scattering in nonideal Bose systems
H. Stein, K. Morawetz, G. Röpke
Medium modification of scattering properties in interacting Bose systems are considered by solving the Bethe-Salpeter equation. An equation of state for the normal phase (generaliz…
Dielectric function of a two-component plasma including collisions
G. Roepke, A. Wierling
A multiple-moment approach to the dielectric function of a dense non-ideal plasma is treated beyond RPA including collisions in Born approximation. The results are compared with th…

K. Morawetz, G. Röpke, Max-Planck-Gesellschaft
The quantum mechanical two - particle problem is considered in hot dense nuclear matter under the influence of a strong electric field such as the field of the residual nucleus in…
Medium modifications of the nucleon--deuteron break--up cross section in the Faddeev approach
M. Beyer, G. Röpke, A. Sedrakian
The three--nucleon scattering problem in a nuclear medium is considered within the Faddeev technique. In particular the deuteron break--up cross section that governs the formation…
