Local Detailed Balance : A Microscopic Derivation

Michel Bauer, Françoise Cornu

Thermal contact is the archetype of non-equilibrium processes driven by constant non-equilibrium constraints when the latter are enforced by reservoirs exchanging conserved microsc…

Strain-induced modulation of Dirac cones and van Hove singularities in twisted graphene bilayer

Viet Hung Nguyen, Philippe Dollfus

By means of atomistic tight-binding calculations, we investigate the effects of uniaxial strain on the electronic bandstructure of twisted graphene bilayer. We find that the bandst…

Random matrices and entanglement entropy of trapped Fermi gases

Pasquale Calabrese, Pierre Le Doussal, Satya N. Majumdar

We exploit and clarify the use of random matrix theory for the calculation of the entanglement entropy of free Fermi gases. We apply this method to obtain analytic predictions for…

Time-delayed Follow-the-Leader model for pedestrians walking in line

Jérôme Fehrenbach, Jacek Narski, Jiale Hua +6

We use the results of a pedestrian tracking experiment to identify a follow-the-leader model for pedestrians walking-in-line. We demonstrate the existence of a time-delay between a…

Asymptotic model for shape resonance control of diatomics by intense non-resonant light: Universality in the single-channel approximation

Anne Crubellier, Rosario González-Férez, Christiane P. Koch +1

Non-resonant light interacting with diatomics via the polarizability anisotropy couples different rotational states and may lead to strong hybridization of the motion. The modifica…

Measurement of the CP-violating phase in decays and limits on penguin effects

LHCb collaboration, R. Aaij, B. Adeva +697

Time-dependent CP violation is measured in the channel for each resonant final state using data collected with an integrated luminosity of 3.0 f…

Defeating jamming with the power of silence: a game-theoretic analysis

Salvatore D'Oro, Laura Galluccio, Giacomo Morabito +3

The timing channel is a logical communication channel in which information is encoded in the timing between events. Recently, the use of the timing channel has been proposed as a c…

Excessive Higgs pair production with little MET from squarks and gluinos in the NMSSM

Ulrich Ellwanger, Ana M. Teixeira

In the presence of a light singlino-like LSP in the NMSSM, the missing transverse energy - MET - signature of squark/gluino production can be considerably reduced. Instead, a pair…

3.55 keV line in Minimal Decaying Dark Matter scenarios

Giorgio Arcadi, Laura Covi, Federico Dradi

We investigate the possibility of reproducing the recently reported $3.55\,\mbox{keV}$ line in some simple decaying dark matter scenarios. In all cases a keV scale decaying DM is c…

Indirect searches for sterile neutrinos at a high-luminosity Z-factory

A. Abada, V. De Romeri, S. Monteil +2

A future high-luminosity -factory will offer the possibility to study rare decays, as those leading to lepton flavour violating final states. Processes such as $Z \to \ell_1…

Spin excitations in the two-dimensional strongly coupled dimer system malachite

E. Canevet, B. Fak, R. K. Kremer +7

The mineral malachite, Cu2(OD)2CO3, has a quantum spin-liquid ground state and no long-range magnetic order down to at least T=0.4 K. Inelastic neutron scattering measurements show…

Geometric phase in Stückelberg interferometry

Lih-King Lim, Jean-Noël Fuchs, Gilles Montambaux

We study the time evolution of a two-dimensional quantum particle exhibiting an energy spectrum, made of two bands, with two Dirac cones, as e.g. in the band structure of a honeyco…
