نویسنده
چکیده
I present here a microscopic theory for the superfluidity of 4 He (He II) derived from experiments, and answer its essential questions. With a " momenton " model, the superfluid is shown to feature as a " harmonic superfluid ". In which a new bonding type, the " superfluid bond " , is formed. Its activation causes the anomalous thermal excitation, the large excess of specific heat, etc. The superfluidity mechanism is recognized being connected to a quantum confinement effect. The theory predicts the basic properties of He II in overall agreements with experiments. The series novel concepts evolved here reverse the current perceptions of 4 He, give significant impact to the understandings of other superfluids.

We have developed a phenomenological quasi-deuteron model to describe photodisintegration reactions of He and He at intermediate photon energies, and compared the results with experimental data obtained by TAGX group in which contributions from photon absorption by pn pair were selectively observed. The data can be reproduced reasonably well, however there still remain certain discrepancies bet...

The chiral two-pion exchange component of the long-range pp interaction is studied in an energy-dependent partial-wave analysis. We demonstrate its presence and importance, and determine the chiral parameters c i (i = 1, 3, 4). The values agree well with those obtained from pion-nucleon amplitudes.

For differential operators which are invariant under the action of an abelian group Bloch theory is the tool of choice to analyze spectral properties. By shedding some new non-commutative light on this we motivate the introduction of a noncommutative Bloch theory for elliptic operators on Hilbert C-modules. It relates properties of C-algebras to spectral properties of module operators such as b...

Using kinetic Monte Carlo simulations and a bond– counting ansatz, thermal stability and diffusion of an adatom island on a crystal surface are studied. At low temperatures, the diffusion constant D is found to decrease for a wide range of island sizes like D ∝ N−α, where α is close to one, N being the number of adatoms in the cluster. By heating up the surface, the system undergoes a phase tra...
