It is very likely that the quantum description of spacetime is quite different from what we perceive at large scales, l ≫ (G~/c3)1/2. The long wavelength description of spacetime, based on Einstein’s equations, is similar to the description of a continuum solid made of a large number of microscopic degrees of freedom. This paradigm provides a novel interpretation of coordinate transformations a...

We present a density functional theory (DFT) calculation in the generalized gradient approximation to study the possibility for the existence of Jahn-Teller (JT) or pseudo Jahn-Teller (PJT) type local distortions in the La-Ba-Cu-O superconducting system. We performed the calculation and correspondingly group theory classification of the electronic ground state of the CuO6 elongated octahedra cl...

Dark matter pair-production in b → s transitions. The flavour-changing neutral current transition b → s can serve as a sensitive probe of WIMP dark matter models, if the WIMP mass is under 2 GeV. In this work we extend our earlier analysis to a generic class of models where the interaction between the dark matter sector and the Standard Model matter sector is mediated by the Higgs boson(s). We ...
متن کاملQuantum Systems and Alternative Unitary Descriptions Received (day Month Year) Revised (day Month Year)
Motivated by the existence of bi-Hamiltonian classical systems and the correspondence principle, in this paper we analyze the problem of finding Hermitian scalar products which turn a given flow on a Hilbert space into a unitary one. We show how different invariant Hermitian scalar products give rise to different descriptions of a quantum system in the Ehrenfest and Heisenberg picture.
متن کاملDynamical Study of Γ Received (day Month Year) Revised (day Month Year)
It has been well recognized that the study of the excitations of the hadrons can shed light on the nonperturbative aspects of QCD. One case which has recently been under intensive study is the electromagnetic (e.m.) excitation of the ∆(1232) resonance. At low four-momentum transfer squared Q, the interest is motivated by the possibility of observing a D−state in the ∆. The existence of a D−stat...
