Quantum Simulator for Transport Phenomena in Fluid Flows
(Nature Publishing Group, 2015-08-17)
Transport phenomena still stand as one of the most challenging problems in computational physics. By exploiting the analogies between Dirac and lattice Boltzmann equations, we develop a quantum simulator based on ...
Slepian models for Gaussian random landscapes
(Springer, 2020-05-27)
Phenomenologically interesting scalar potentials are highly atypical in generic random landscapes. We develop the mathematical techniques to generate constrained random potentials, i.e.Slepian models, which can globally ...
A continued fraction based approach for the Two-photon Quantum Rabi Model
(Nature Publishing, 2019-03-11)
We study the Two Photon Quantum Rabi Model by way of its spectral functions and survival probabilities. This approach allows numerical precision with large truncation numbers, and thus exploration of the spectral collapse. ...
Non-Abelian anomalies and hadronic fluids
(IOP, 2019)
By using differential geometry methods, we study the role of non-Abelian anomalies in relativistic fluids. We obtain closed expressions for the covariant currents derived from the Chern-Simons effective action. Our results ...
Thermodynamics of Resonant Scalars in AdS/CFT and implications for QCD
(E. D. P Sciences, 2016)
We explore the thermodynamics of a simple 5D Einstein-dilaton gravity model with a massive scalar field, with asymptotically AdS behavior in the UV. The holographic renormalization is addressed in details, and analytical ...
Solitons and black hole in shift symmetric scalar-tensor gravity with cosmological constant
(Springer, 2018-06-14)
We demonstrate the existence of static, spherically symmetric globally regular, i.e. solitonic solutions of a shift-symmetric scalar-tensor gravity model with negative cosmological constant. The norm of the Noether current ...
Fitting BICEP2 with defects, primordial gravitational waves and dust
(IOP Publishing, 2015)
In this work we discuss the possibility of cosmic defects being responsible for the B-mode signal measured by the BICEP2 collaboration. We also allow for the presence of other cosmological sources of B-modes such as ...
Double layers in gravity theories
(IOP Publishing, 2015)
Gravitational double layers, unlike their classical electromagnetic counterparts, are thought to be forbidden in gravity theories. It has been recently shown, however, that they are feasible in, for instance, gravity ...
Hartle's model within the general theory of perturbatiye matchings: the change in mass
(IOP Publishing, 2015)
Hartle's model provides the most widely used analytic framework to describe isolated compact bodies rotating slowly in equilibrium up to second order in perturbations in the context of General Relativity. Apart from some ...
