Publicado el libro “Quantum Information and Quantum Optics with Superconducting Circuits”

2022-09-21T10:53:15+02:00Tags: , , , , |

Nuestro compañero Juan José García-Ripoll acaba de publicar recientemente el libro "Quantum Information and Quantum Optics with Superconducting Circuits" (Cambridge University Press, agosto de 2022). El libro está dirigido principalmente a estudiantes universitarios y jóvenes investigadores. Nuestro compañero explora el uso de las propiedades de la superconductividad en sistemas cuánticos, cómo emulan fotones y átomos [...]

Harnessing nonadiabatic excitations promoted by a quantum critical point: Quantum battery and spin squeezing

2022-09-19T17:23:42+02:00Tags: , |

Authors: Abah, O.; De Chiara, G.; Paternostro, M.; Puebla, R. Journal: PHYSICAL REVIEW RESEARCH Publication date: 2022/04/22 DOI: 10.1103/PhysRevResearch.4.L022017 Abstract: Crossing a quantum critical point in finite time challenges the adiabatic condition due to the closing of the energy gap, which ultimately results in the formation of excitations. Such nonadiabatic excitations are typically deemed detrimental [...]

Atom scattering as a probe of the surface electron-phonon interaction at conducting surfaces

2022-09-19T17:24:17+02:00Tags: |

Authors: Manson, J. R.; Benedek, G.; Miret-Artés, S. Journal: SURFACE SCIENCE REPORTS Publication date: 2022/05/01 DOI: 10.1016/j.surfrep.2022.100552 Abstract: An atomic projectile colliding with a surface at kinetic energies in the thermal or hyperthermal range interacts with and is reflected by the electronic density well in front of the first layer of target atoms, and it [...]

Delving into guest-free and He-filled sI and sII clathrate hydrates: a first-principles computational study

2022-09-19T17:24:47+02:00Tags: , , , |

Authors: Yanes-Rodríguez, R.; Cabrera-Ramírez, A.; Prosmiti, R. Journal: PHYSICAL CHEMISTRY CHEMICAL PHYSICS Publication date: 2022/06/01 DOI: 10.1039/d2cp00701k Abstract: The dynamics of the formation of a specific clathrate hydrate as well as its thermodynamic transitions depend on the interactions between the trapped molecules and the host water lattice. The molecular-level understanding of the different underlying processes [...]

Modeling of Structure H Carbon Dioxide Clathrate Hydrates: Guest-Lattice Energies, Crystal Structure, and Pressure Dependencies

2022-09-08T20:22:00+02:00Tags: |

Authors: Cabrera-Ramirez, Adriana; Prosmiti, Rita Journal: JOURNAL OF PHYSICAL CHEMISTRY C Publication date: 2022/09/08 DOI: 10.1021/acs.jpcc.2c04140 Abstract: We performed first-principles computations to investigate the complex interplay of molecular interaction energies in determining the lattice structure and stability of CO2@sH clathrate hydrates. Density functional theory computations using periodic boundary conditions were employed to characterize energetics and [...]

They [...]

The role of highly vibrationally excited H-2 initiating the nitrogen chemistry Quantum study and 3 sigma – detection of NH emission in the Orion Bar PDR

2022-08-31T20:22:00+02:00Tags: |

Authors: Goicoechea, Javier R.; Roncero, Octavio Journal: ASTRONOMY & ASTROPHYSICS Publication date: 2022/08/31 DOI: 10.1051/0004-6361/202243884 Abstract: The formation of hydrides by gas-phase reactions between H-2 and a heavy element atom is a very selective process. Reactions with ground-state neutral carbon, oxygen, nitrogen, and sulfur atoms are very endoergic and have high energy barriers because the [...]
