The Transport Model Evaluation Project (TMEP) has been pursued to test the robustness of transport model predictions to reach consistent conclusions from the same type of physical model. To this end, calculations under controlled conditions of physical input and set-up were performed by the various participating codes. These included both calculations of nuclear matter in a periodic box, which test individual ingredients of a transport code, and calculations of complete collisions of heavy ions. Over the years, five studies were performed within this project. They show, on one hand, that in box calculations the differences between the codes can be well understood and a convergence of the results can be reached. These studies also highlight the systematic differences between the two families of transport codes, known under the names of Boltzmann-Uehling-Uhlenbeck (BUU) and Quantum Molecular Dynamics (QMD) type codes. On the other hand, there still exist substantial differences when these codes are applied to real heavy-ion collisions. The results of transport simulations of heavy-ion collisions will have more significance if codes demonstrate that they can verify benchmark calculations such as the ones studied in these evaluations.

Times Cited Count：22 Percentile：77.11(Physics, Nuclear)Inclusive proton emission from deuteron-induced reactions on various nuclear targets at an incident energy of 100 MeV are analyzed using the CDCC theory for elastic breakup process and the Glauber model for neutron stripping process. Moreover, the phenomenological moving source model is used to estimate evaporation and pre-equilibrium components in inclusive spectra. The calculation reproduces fairly well a prominent bump in experimental spectra for light and medium nuclei at forward angles of less than 20, whereas the calculation underestimates the bump component as target atomic number increases. The underestimation is likely to be attributed to the fact that the eikonal approximation used in the Glauber model becomes worse due to strong Coulomb interaction. It is shown that the Glauber model calculation for neutron stripping process leads to improvement of this discrepancy by substituting the eikonal phase shift for the quantum phase shift.

Times Cited Count：276 Percentile：98.66(Multidisciplinary Sciences)The nature of the pseudogap phase of cuprate high-temperature superconductors is a major unsolved problem in condensed matter physics. We studied the commencement of the pseudogap state at temperature 
using three different techniques (angle-resolved photoemission spectroscopy, polar Kerr effect, and time-resolved reflectivity) on the same optimally doped Bi2201 crystals. We observed the coincident, abrupt onset at of a particle-hole asymmetric antinodal gap in the electronic spectrum, a Kerr rotation in the reflected light polarization, and a change in the ultrafast relaxational dynamics, consistent with a phase transition. Upon further cooling, spectroscopic signatures of superconductivity begin to grow close to the superconducting transition temperature (
), entangled in an energy-momentum dependent manner with the preexisting pseudogap features, ushering in a ground state with coexisting orders.

Times Cited Count：5 Percentile：16.83(Polymer Science)Various topological phase diagrams of blends of main-chain liquid crystalline polymer (MCLCP) and flexible polymer have been established theoretically in the frame-work of Matsuyama-Kato theory by combining Flory-Hussing (FH) free energy for isotropic mixing, Maier-Saupe (MS) free energy for nematic ordering in the constituent MCLCP, and free energy pertaining to polymer chain-rigidity. The calculated phase diagrams exhibit liquidus and solidus lines along with a nematic-isotropic (NI) transition of the constituent MCLCP. Subsequently, thermodynamic parameters estimated from the phase diagrams hitherto established have been employed in the numerical computation to elucidate phase separation dynamics and morphology evolution accompanying thermal-quench induced phase separation of the MCLCP/polymer mixture.
