Quenches to the critical point of the three-state Potts model: Matrix product state simulations and conformal field theory

2022-09-19T15:57:15+02:00Tags: , , , |

Authors: Robertson, Niall F.; Surace, Jacopo; Tagliacozzo, Luca Journal: PHYSICAL REVIEW B Publication date: 2022/05/04 DOI: 10.1103/PhysRevB.105.195103 Abstract: Conformal field theories (CFTs) have been used extensively to understand the physics of critical lattice models at equilibrium. However, the applicability of CFT calculations to the behavior of the lattice systems in the out-of-equilibrium setting is not [...]

Helium Isotopes Quantum Sieving through Graphtriyne Membranes

Authors: Hernandez, Marta I.; Bartolomei, Massimiliano; Campos-Martinez, Jose Journal: NANOMATERIALS Publication date: 2021/01/01 DOI: 10.3390/nano11010073 Abstract: We report accurate quantum calculations of the sieving of Helium atoms by two-dimensional (2D) graphtriyne layers with a new interaction potential. Thermal rate constants and permeances in an ample temperature range are computed and compared for both Helium isotopes. [...]

Authors: Roslawska, Anna; Merino, Pablo; Leon, Christopher C.; Grewal, Abhishek; Etzkorn, Markus; Kuhnke, Klaus; Kern, Klaus Journal: NANO LETTERS Publication date: 2021/06/09 DOI: 10.1021/acs.nanolett.1c00328 Abstract: Light sources on the scale of single molecules can be addressed and characterized at their proper sub-nanometer scale by scanning tunneling microscopy-induced luminescence (STML). Such a source can be driven [...]

Atomic-Scale Structural Fluctuations of a Plasmonic Cavity

Authors: Roslawska, Anna; Merino, Pablo; Grewal, Abhishek; Leon, Christopher C.; Kuhnke, Klaus; Kern, Klaus Journal: NANO LETTERS Publication date: 2021/09/08 DOI: 10.1021/acs.nanolett.1c02207 Abstract: Optical spectromicroscopies, which can reach atomic resolution due to plasmonic enhancement, are perturbed by spontaneous intensity modifications. Here, we study such fluctuations in plasmonic electroluminescence at the single-atom limit profiting from the [...]

Closed timelike curves and chronology protection in quantum and classical simulators

2021-02-12T10:08:13+01:00Tags: , , |

Authors: Martin-Vazquez, Gonzalo; Sabin, Carlos Contribution: Article Journal: CLASSICAL AND QUANTUM GRAVITY Publication date: 2020/02/20 DOI: 10.1088/1361-6382/ab5f3f Abstract: In principe, general relativity seems to allow the existence of closed timelike curves (CTC). However, when quantum effects are considered, it is likely that their existence is prevented by some kind of chronological protection mechanism, as Hawking conjectured. [...]

Here it is shown that [...]

The Electron-Phonon Interaction of Low-Dimensional and Multi-Dimensional Materials from He Atom Scattering

Authors: Benedek, Giorgio; Manson, Joseph R.; Miret-Artes, Salvador Contribution: Article; Early Access Journal: ADVANCED MATERIALS Publication date: 2020/06/01 DOI: 10.1002/adma.202002072 Abstract: Atom scattering is becoming recognized as a sensitive probe of the electron-phonon interaction parameter lambda at metal and metal-overlayer surfaces. Here, the theory is developed, linking lambda to the thermal attenuation of atom scattering spectra [...]
