    Nuclear multifragmentation, its relation to general physics

    Heat can flow from cold to hot at any phase separation even in macroscopic systems. Therefore also Lynden-Bell's famous gravo-thermal catastrophe must be reconsidered. In contrast to traditional canonical Bolt...

    Thermodynamics of rotating self-gravitating systems

    We investigate the statistical equilibrium properties of a system of classical particles interacting via Newtonian gravity, enclosed in a three-dimensional spherical volume. Within a mean-field approximation, we ...

    On the fragmentation of multiply charged sodium clusters

    The fragmentation of multiply charged atomic sodium clusters of mass 200 is investigated using the Micro-canonical Metropolis Monte Carlo (MMMC) statistical technique for excitation energies up to 200 eV and f...

    Phase transitions in “small” systems

    Traditionally, phase transitions are defined in the thermodynamic limit only. We discuss how phase transitions of first order (with phase separation and surface tension), continuous transitions and (multi)-cri...

    Experimental and theoretical search for a phase transition in nuclear fragmentation

    Phase transitions of small isolated systems are signaled by the shape of the caloric equation of state e *(T), the relationship between the excitation energy per nucleon e * and temperature. In this work we comp...

    Phase Transitions without Thermodynamic Limit

    “In the thermodynamic limit the canonical and the microcanonical ensemble are equivalent in all details and generality.” Statements like this are found in many textbooks of statistical thermodyna...

    Fission of doubly charged iron and aluminium clusters

    We present a statistical fragmentation study of doubly charged iron and aluminum clusters of less than 60 atoms. At low excitation energies we find that the evaporation of one charged monomer is the most proba...

    Cluster fragmentation, a laboratory for thermodynamics and phase-transitions in particular

    A micro-canonical formulation of thermodynamics is presented which allows for a consistent application to small as also large systems and the unambiguous identification of phase transitions even in mesoscopic ...

    Fragmentation phase transition in atomic clusters II

    We present a statistical fragmentation study of doubly charged alkali (Li, Na, K) and antimony clusters. The evaporation of one charged trimer is the most dominant decay channel (asymmetric fission) at low exc...

    Fragmentation phase transitions in atomic clusters III

    We discuss the role and the treatment of polarization effects in many-body systems of charged conducting clusters and apply this to the statistical fragmentation of Naclusters. We see a first order microcanoni...

    Fragmentation phase transition in atomic clusters IV

    Within the micro-canonical ensemble it is well possible to identify phase-transitions in small systems. The consequences for the understanding of phase transitions in general are discussed by studying three re...

    Fragmentation phase transition in atomic clusters I

    The volume W of the accessible N-body phase space and its dependence on the total energy is directly calculated. The famous Boltzmann relation S = k * ln(W) defines microcanonical thermodynamics (MT). We study ho...

    Evaporation of hot mesoscopic atomic metal clusters

    The evaporation times of hot mesoscopic sodium clusters are estimated using the microscopic and microcanonical statistical model of Weisskopf and the macroscopic canonical kinetic gas theory. The level density...

    Statistical fragmentation of hot atomic metal clusters

    Fragmentation processes of highly excited neutral and charged atomic metal clusters are studied in the framework of an equilibrium statistical model. In the particular case of hot (near and above melting) neut...

    Statistical multifragmentation

    Two scenarios for the fragmentation of nuclei in collisions at intermediate energies are conceivable: A fast direct “shattering” or “abrasion — ablation” of a cluster has frequently been proposed in high-energ...

    Microcanonical Monte Carlo

    The generic properties of finite equilibrised many-body systems under the action of long-range forces are discussed. The microcanonical thermodynamics of such system is developed. As realistic example the multifr...
