Structural and dynamical properties of superfluid helium: a density functional approach
F. Dalfovo, A. Lastri, L. Pricaupenko +2
We present a novel density functional for liquid 4He, properly accounting for the static response function and the phonon-roton dispersion in the uniform liquid. The functional is…
Contractions on a manifold polarized by an ample vector bundle
M. Andreatta, M. Mella
A complex manifold of dimension together with an ample vector bundle on it will be called a {\sf generalized polarized variety}. The adjoint bundle of the pair …
Operator Formalism on General Algebraic Curves
F. Ferrari, J. Sobczyk
The usual Laurent expansion of the analytic tensors on the complex plane is generalized to any closed and orientable Riemann surface represented as an affine algebraic curve. As an…
A simple approach to the correlation of rotovibrational states in four-atomic molecules
N. Manini, S. Oss
The problem of correlation between quantum states of four-atomic molecules in different geometrical configurations is reviewed in detail. A general, still simple rule is obtained w…
Hadron Correlators and the Structure of the Quark Propagator
A. Ferrando, V. Vento
The structure of the quark propagator of in a confining background is not known. We make an Ansatz for it, as hinted by a particular mechanism for confinement, and analyze it…
On the High-Temperature Behaviour of the Closed Superstring
S. Dusini, S. Zerbini
The high-temperature expansion for closed superstring one-loop free energy is studied. The Laurent series representation is obtained and its sum is analytically continued in order…
Von Neumann Algebra Automorphisms and Time-Thermodynamics Relation in General Covariant Quantum Theories
A. Connes, C. Rovelli
We consider the cluster of problems raised by the relation between the notion of time, gravitational theory, quantum theory and thermodynamics; in particular, we address the proble…
Interaction of Low - Energy Induced Gravity with Quantized Matter and Phase Transition Induced by Curvature
I. L. Shapiro, G. Cognola
At high energy scale the only quantum effect of any asymptotic free and asymptotically conformal invariant GUT is the trace anomaly of the energy-momentum tensor. Anomaly generates…
Are p-Branes Asymptotically Black Holes?
Andrei Bytsenko, Klaus Kirsten, Sergio Zerbini
An attempt is made to compare the asymptotic state density of twisted -branes and the related state density of mass level of a -dimensional neutral black hole. To this ai…
Dispersion of Ripplons in Superfluid 4he
A. Lastri, F. Dalfovo, L. Pitaevskii +1
A detailed study of the dispersion law of surface excitations in liquid \hef at zero temperature is presented, with special emphasis to the short wave length region. The hybridizat…
Asymptotic Level State Density for Parabosonic Strings
A. A. Bytsenko, S. D. Odintsov, S. Zerbini
Making use of some results concerning the theory of partitions, relevant in number theory, the complete asymptotic behavior, for large , of the level density of states for a par…
Haldane's Fractional Statistics and the Riemann-Roch Theorem
Dingping Li, Stéphane Ouvry
The new definition of fractional statistics given by Haldane can be understood in some special cases in terms of the Riemann-Roch theorem.
Effects of Disorder in a Dilute Bose Gas
S. Giorgini, L. Pitaevskii, S. Stringari
We discuss the effects of a weak random external potential on the properties of the dilute Bose gas at zero temperature. The results recently obtained by Huang and Meng for the dep…
Thermal states in Anti-de Sitter space-time and the role of time-like infinity
L. Vanzo, G. Turco
The grand-canonical thermodynamic potential for Bose and Fermi fields in anti-de Sitter space-time is introduced and a Mellin complex representation is given. This is used to inves…
Fermions in Quantum Gravity
H A Marales-Tecotl, C Rovelli
We study the quantum fermions+gravity system, that is, the gravitational counterpart of QED. We start from the standard Einstein-Weyl theory, reformulated in terms of Ashtekar vari…
