Constructing algebraic groups from their Lie algebras
Willem de Graaf
A connected algebraic group in characteristic 0 is uniquely determined by its Lie algebra. In this paper an algorithm is given for constructing an algebraic group in characteristic…
Study of distortion effects and clustering of isotopic impurities in solid molecular para-hydrogen by Shadow Wave Functions
Francesco Operetto, Francesco Pederiva
We employed a fully optimized Shadow Wave Function (SWF) in combination with Variational Monte Carlo techniques to investigate the properties of HD molecules and molecular ortho-de…
Diffusion Monte Carlo study of the equation of state of solid ortho-D
Francesco Operetto, Francesco Pederiva
We present results of Diffusion Monte Carlo calculations for a system of solid ortho-D_2 at different densities, for pressure ranging from 0 up to 350MPa. We compare the equation o…
Inclusive electron scattering off 4He
S. Bacca, H. Arenhoevel, N. Barnea +2
Inclusive electron scattering off 4He is calculated exactly with a complete treatment of the final state interaction within a simple semirealistic potential model. We discuss resul…
Metastable states of a gas of dipolar bosons in a 2D optical lattice
C. Menotti, C. Trefzger, M. Lewenstein
We investigate the physics of dipolar bosons in a two dimensional optical lattice. It is known that due to the long-range character of dipole-dipole interaction, the ground state p…
Decoherence induced by interacting quantum spin baths
Davide Rossini, Tommaso Calarco, Vittorio Giovannetti +2
We study decoherence induced on a two-level system coupled to a one-dimensional quantum spin chain. We consider the cases where the dynamics of the chain is determined by the Ising…
Some recent results in scalar quantum field theory in globally hyperbolic asymptotically flat spacetimes
Valter Moretti
Some recent results obtained by the author and collaborators about QFT in asymptotically flat spacetimes at null infinity are summarized and reviewed. In particular it is focused o…
Constructing algebraic Lie algebras
Claus Fieker, Willem de Graaf
We give an algorithm for constructing the algebraic hull of a given matrix Lie algebra in characteristic zero. It is based on an algorithm for finding integral linear dependencies…
Quantum vacuum radiation spectra from a semiconductor microcavity with a time-modulated vacuum Rabi frequency
Simone De Liberato, Cristiano Ciuti, Iacopo Carusotto
We develop a general theory of the quantum vacuum radiation generated by an arbitrary time-modulation of the vacuum Rabi frequency for an intersubband transition of a doped quantum…
Upper limits to surface force disturbances on LISA proof masses and the possibility of observing galactic binaries
Ludovico Carbone, Giacomo Ciani, Rita Dolesi +5
We report on the measurement of parasitic surface force noise on a hollow replica of a LISA (Laser Interferometer Space Antenna for the observation of gravitational waves) proof ma…
Torsion pendulum facility for direct force measurements of LISA GRS related disturbances
L. Carbone, A. Cavalleri, G. Ciani +5
A four mass torsion pendulum facility for testing of the LISA GRS is under development in Trento. With a LISA-like test mass suspended off-axis with respect to the pendulum fiber,…
Robust optimal quantum gates for Josephson charge qubits
Simone Montangero, Tommaso Calarco, Rosario Fazio
Quantum optimal control theory allows to design accurate quantum gates. We employ it to design high-fidelity two-bit gates for Josephson charge qubits in the presence of both leaka…
String-inspired Gauss-Bonnet gravity reconstructed from the universe expansion history and yielding the transition from matter dominance to dark energy
Guido Cognola, Emilio Elizalde, Shin'ichi Nojiri +2
We consider scalar-Gauss-Bonnet and modified Gauss-Bonnet gravities and reconstruct these theories from the universe expansion history. In particular, we are able to construct vers…
Structure, superfluidity, and quantum melting of hydrogen clusters
Fabio Mezzacapo, Massimo Boninsegni
We present results of a theoretical study of para-hydrogen and ortho-deuterium clusters at low temperature (0.5 K < T < 3.5 K), based on Path Integral Monte Carlo simulations. Clus…
Measuring the one-particle excitations of ultracold fermionic atoms by stimulated Raman spectroscopy
Tung-Lam Dao, Antoine Georges, Jean Dalibard +2
We propose a Raman spectroscopy technique which is able to probe the one-particle Green's function, the Fermi surface, and the quasiparticles of a gas of strongly interacting ultra…
Stability of Bose-Einstein condensates in a Kronig-Penney potential
Ippei Danshita, Shunji Tsuchiya
We study the stability of Bose-Einstein condensates with superfluid currents in a one-dimensional periodic potential. By using the Kronig-Penney model, the condensate and Bogoliubo…
Spectral analysis and zeta determinant on the deformed spheres
M. Spreafico, S. Zerbini
We consider a class of singular Riemannian manifolds, the deformed spheres , defined as the classical spheres with a one parameter family of singular Riemannian struc…
Many-body physics of a quantum fluid of exciton-polaritons in a semiconductor microcavity
Iacopo Carusotto, Michiel Wouters, Cristiano Ciuti
Some recent results concerning nonlinear optics in semiconductor microcavities are reviewed from the point of view of the many-body physics of an interacting photon gas. Analogies…
Thin loop algebras of Albert-Zassenhaus algebras
Marina Avitabile, Sandro Mattarei
Thin Lie algebras are Lie algebras over a field, graded over the positive integers and satisfying a certain narrowness condition. In particular, all homogeneous components have dim…
On localization and position operators in Moebius-covariant theories
Nicola Pinamonti
Some years ago it was shown that, in some cases, a notion of locality can arise from the group of symmetry enjoyed by the theory, thus in an intrinsic way. In particular, when Moeb…
Optimized Schwarz Methods for Maxwell equations
Victorita Dolean, Martin Gander, Luca Gerardo-Giorda
Over the last two decades, classical Schwarz methods have been extended to systems of hyperbolic partial differential equations, and it was observed that the classical Schwarz meth…
