• (IOP Publishing, 2012-02-27)
We analyze quantum quenches in integrable models and in particular the determination of the initial state in the basis of eigenstates of the post-quench hamiltonian. This leads us to consider the set of transformations of ...

• (2008-01-29)
The zero modes' Fock space for the extended chiral $su(2)$ WZNW model gives room to a realization of the Grothendieck fusion ring of representations of the restricted $U_q sl(2)$ quantum universal enveloping algebra (QUEA) ...
• (2007-10-24)
We prove the existence of a lower semicontinuous value function for Bolza problem in differential games with state-constraints. As a byproduct, we obtain a new estimation of trajectories of a control system by trajectories ...
• (American Physical Society, 2009-09-14)
The lattice dynamics of hcp crystalline 4He is studied at zero temperature and for two different densities (near and far from melting), using a ground-state path-integral quantum Monte Carlo technique. The complete phonon ...
• (American Physical Society, 2005-06-23)
Using exact diagonalizations and Green's function Monte Carlo simulations, we have studied the zero-temperature properties of the quantum dimer model on the triangular lattice on clusters with up to 588 sites. A detailed ...
• (Society for Neuroscience, 2000)
Zinc is abundantly present in the CNS, and after nerve stimulation is thought to be released in sufficient quantity to modulate the synaptic transmission. Although it is known that this divalent cation inhibits the GABAergic ...
• (Wiley, 1996-10)
Intracellular recordings were used to study the effects of zinc on the bicuculline-sensitive and -insensitive responses evoked by GABA in CA3 rat hippocampal neurons in slices obtained from postnatal day (P) 0 to P8. In ...
• (SISSA, 2015-11-16)
α-Synuclein (α-syn) plays a central role in the pathogenesis of neurodegenerative disorders collectively known as “synucleinopathies” that include Parkinson’s disease (PD), dementia with Lewy bodies (DLB) and multiple ...
• (Springer, 2012-08)
Let $X$ be a complex smooth projective variety, and $\mathcal{G}$ a locally free sheaf on $X$. We show that there is a 1-to-1 correspondence between pairs $(\Lambda,\Xi)$, where $\Lambda$ is a sheaf of almost polynomial ...
• (American Physical Society, 2014)
In the simplest inflationary model V=12m2φ2, we provide a prediction accurate up to 1% for the spectral index ns and the tensor-to-scalar ratio r assuming instantaneous reheating and a standard thermal history: ns=0.9668±0.0003 ...
• (American Physical Society, 2014)
The simplest inflationary model V=12m2φ2 represents the benchmark for future constraints. For a quadratic potential, the quantity (ns-1)+r/4+11(ns-1) 2/24 vanishes (up to corrections which are cubic in slow roll) and can ...
• (Springer, 2014)
We formulate a deformation of Rozansky-Witten theory analogous to the $\Omega$-deformation. It is applicable when the target space $X$ is hyperk\"ahler and the spacetime is of the form $\mathbb{R} \times \Sigma$, ...
