Quantum Simulation of Dissipative Processes without Reservoir Engineering.

Scientific reports

Di Candia R, Pedernales JS, del Campo A, Solano E, Casanova J.
PMID: 26024437
Sci Rep. 2015 May 29;5:9981. doi: 10.1038/srep09981.

We present a quantum algorithm to simulate general finite dimensional Lindblad master equations without the requirement of engineering the system-environment interactions. The proposed method is able to simulate both Markovian and non-Markovian quantum dynamics. It consists in the quantum...

Crossover from super- to subdiffusive motion and memory effects in crystalline organic semiconductors.

Physical review letters

De Filippis G, Cataudella V, Mishchenko AS, Nagaosa N, Fierro A, de Candia A.
PMID: 25768773
Phys Rev Lett. 2015 Feb 27;114(8):086601. doi: 10.1103/PhysRevLett.114.086601. Epub 2015 Feb 24.

The transport properties at finite temperature of crystalline organic semiconductors are investigated, within the Su-Schrieffer-Heeger model, by combining an exact diagonalization technique, Monte Carlo approaches, and a maximum entropy method. The temperature-dependent mobility data measured in single crystals of...

Eradication of high viable loads of Listeria monocytogenes contaminating food-contact surfaces.

Front Microbiol. 2015 Jul 16;6:733. doi: 10.3389/fmicb.2015.00733. eCollection 2015.

This study demonstrates the efficacy of cold gaseous ozone treatments at low concentrations in the eradication of high Listeria monocytogenes viable cell loads from glass, polypropylene, stainless steel, and expanded polystyrene food-contact surfaces. Using a step by step approach,...

Lattice glass model with no tendency to crystallize.

Physical review. E, Statistical, nonlinear, and soft matter physics

Ciamarra MP, Tarzia M, de Candia A, Coniglio A.
PMID: 12786326
Phys Rev E Stat Nonlin Soft Matter Phys. 2003 May;67(5):057105. doi: 10.1103/PhysRevE.67.057105. Epub 2003 May 28.

We study a lattice model with two-body interactions that reproduces in three dimensions many features of structural glasses, such as cage effect and vanishing diffusivity. While having a crystalline state at low temperatures, it does not crystallize when quenched,...

Dynamical heterogeneity in a model for permanent gels: different behavior of dynamical susceptibilities.

Physical review. E, Statistical, nonlinear, and soft matter physics

Abete T, de Candia A, Del Gado E, Fierro A, Coniglio A.
PMID: 18999424
Phys Rev E Stat Nonlin Soft Matter Phys. 2008 Oct;78(4):041404. doi: 10.1103/PhysRevE.78.041404. Epub 2008 Oct 14.

We present a systematic study of dynamical heterogeneity in a model for permanent gels upon approaching the gelation threshold. We find that the fluctuations of the self-intermediate scattering function are increasing functions of time, reaching a plateau whose value,...

Jamming transition in granular media: a mean-field approximation and numerical simulations.

Physical review. E, Statistical, nonlinear, and soft matter physics

Fierro A, Nicodemi M, Tarzia M, de Candia A, Coniglio A.
PMID: 16089733
Phys Rev E Stat Nonlin Soft Matter Phys. 2005 Jun;71(6):061305. doi: 10.1103/PhysRevE.71.061305. Epub 2005 Jun 28.

In order to study analytically the nature of the jamming transition in granular material, we have considered a cavity method mean-field theory, in the framework of a statistical mechanics approach, based on Edwards' original idea. For simplicity, we have...

Embedding quantum simulators for quantum computation of entanglement.

Physical review letters

Di Candia R, Mejia B, Castillo H, Pedernales JS, Casanova J, Solano E.
PMID: 24483635
Phys Rev Lett. 2013 Dec 13;111(24):240502. doi: 10.1103/PhysRevLett.111.240502. Epub 2013 Dec 09.

We introduce the concept of embedding quantum simulators, a paradigm allowing the efficient quantum computation of a class of bipartite and multipartite entanglement monotones. It consists in the suitable encoding of a simulated quantum dynamics in the enlarged Hilbert...

Relaxation process and dynamical heterogeneities in chemical gels: critical behavior of self-overlap and its fluctuation.

The journal of physical chemistry. B

Fierro A, Abete T, de Candia A, Coniglio A.
PMID: 21770381
J Phys Chem B. 2011 Dec 08;115(48):14274-9. doi: 10.1021/jp205224t. Epub 2011 Jul 19.

We study the dynamical behavior in chemical gelation, as the gelation threshold is approached from the sol phase. On the basis of the heterogeneous diffusion due to the cluster size distribution, as expected by the percolation theory, we predict...

We study the dynamical properties of a model for charged colloidal particles, performing molecular dynamics simulations and observing the behavior of bond persistence functions, self-intermediate scattering functions at different wave vectors, and mean-square displacements of the particles, in three...

Finite-time quantum entanglement in propagating squeezed microwaves.

Scientific reports

Fedorov KG, Pogorzalek S, Las Heras U, Sanz M, Yard P, Eder P, Fischer M, Goetz J, Xie E, Inomata K, Nakamura Y, Di Candia R, Solano E, Marx A, Deppe F, Gross R.
PMID: 29686396
Sci Rep. 2018 Apr 23;8(1):6416. doi: 10.1038/s41598-018-24742-z.

Two-mode squeezing is a fascinating example of quantum entanglement manifested in cross-correlations of non-commuting observables between two subsystems. At the same time, these subsystems themselves may contain no quantum signatures in their self-correlations. These properties make two-mode squeezed (TMS)...

Reduction of whey protein concentrate antigenicity by using a combined enzymatic digestion and ultrafiltration approach.

Journal of food science and technology

Quintieri L, Monaci L, Baruzzi F, Giuffrida MG, de Candia S, Caputo L.
PMID: 28720947
J Food Sci Technol. 2017 Jun;54(7):1910-1916. doi: 10.1007/s13197-017-2625-5. Epub 2017 Apr 28.

The global interest in saving food resources is leading to recycle wasted-food materials to extract useful nutrients. In dairy industry, the recycling of whey proteins determines their utilization in the healthy-addressed foods, which, however, can cause immunological responses in...

The clinical benefit of convalescent plasma (CP) for patients with coronavirus disease (COVID)-19 is still debated. In this systematic review and meta-analysis, we selected 10 randomized clinical trials (RCTs) and 15 non-randomized studies (total number of patients = 22,591)...
