Generic emergence of objectivity of observables in infinite dimensions (2018)
Journal Article
Knott, P. A., Tufarelli, T., Piani, M., & Adesso, G. (2018). Generic emergence of objectivity of observables in infinite dimensions. Physical Review Letters, 121(16), Article 160401. https://doi.org/10.1103/PhysRevLett.121.160401

Quantum Darwinism posits that information becomes objective whenever multiple observers indirectly probe a quantum system by each measuring a fraction of the environment. It was recently shown that objectivity of observables emerges generically from... Read More about Generic emergence of objectivity of observables in infinite dimensions.

Certification and quantification of multilevel quantum coherence (2018)
Journal Article
Ringbauer, M., Bromley, T. R., Cianciaruso, M., Lami, L., Lau, W. S., Adesso, G., White, A. G., Fedrizzi, A., & Piani, M. (2018). Certification and quantification of multilevel quantum coherence. Physical Review X, 8(4), Article 041007. https://doi.org/10.1103/physrevx.8.041007

Quantum coherence, present whenever a quantum system exists in a superposition of multiple classically distinct states, marks one of the fundamental departures from classical physics. Quantum coherence has recently been investigated rigorously within... Read More about Certification and quantification of multilevel quantum coherence.

The effect of forest dislocations on the evolution of a phase-field model for plastic slip (2018)
Journal Article
Dondl, P., Kurzke, M., & Wojtowytsch, S. (2019). The effect of forest dislocations on the evolution of a phase-field model for plastic slip. Archive for Rational Mechanics and Analysis, 232(1), 65–119. https://doi.org/10.1007/s00205-018-1317-2

We consider the gradient flow evolution of a phase-field model for crystal dislocations in a single slip system in the presence of forest dislocations. The model is based on a Peierls-Nabarro type energy penalizing non-integer slip and elastic stress...

Elastodynamics on graphs: wave propagation on networks of plates (2018)
Journal Article
Brewer, C., Creagh, S. C., & Tanner, G. (2018). Elastodynamics on graphs: wave propagation on networks of plates. Journal of Physics A: Mathematical and Theoretical, 51(44), Article 445101. https://doi.org/10.1088/1751-8121/aae1d2

We consider the wave dynamics on networks of plates coupled along 1D joints. This set-up can be mapped onto an extension of wave graph systems studied in, for example, quantum graph theory. In the elastic case, different mode-types (flexural, longitu... Read More about Elastodynamics on graphs: wave propagation on networks of plates.

Thermality from a Rindler quench (2018)

© 2018 IOP Publishing Ltd. Ultracold fermionic atoms in an optical lattice, with a sudden position-dependent change (a quench) in the effective dispersion relation, have been proposed by Rodríguez-Laguna et al as an analogue spacetime test of the Unr...

The structure of a dewetting rim with strong slip: the long-time evolution (2018)
Journal Article
Evans, P., King, J., & Münch, A. (2018). The structure of a dewetting rim with strong slip: the long-time evolution. Multiscale Modeling and Simulation: A SIAM Interdisciplinary Journal, 16(3), 1365-1391. https://doi.org/10.1137/15M1051221

When a thin viscous film dewets from a solid substrate, the liquid forms a characteristic rim near the contact line as the contact line retracts. The shape of the rim and also the retraction rate vary strongly with the amount of slip that occurs at t...

The geometry of Sloppiness (2018)
Journal Article
Raman, D. V., Harrington, H. A., Dufresne, E., Harrington, H. A., & Raman, D. V. (in press). The geometry of Sloppiness. Journal of Algebraic Statistics, 9(1), 30-68

The use of mathematical models in the sciences often involves the estimation of unknown parameter values from data. Sloppiness provides information about the uncertainty of this task. In this paper, we develop a precise mathematical foundation for sl... Read More about The geometry of Sloppiness.

Fermions, differential forms and doubled geometry (2018)
Journal Article
Krasnov, K. (2018). Fermions, differential forms and doubled geometry. Nuclear Physics B, 936, 36-75. https://doi.org/10.1016/j.nuclphysb.2018.09.006

© 2018 The Author We show that all fermions of one generation of the Pati–Salam version of the Standard Model (SM) can be elegantly described by a single fixed parity (say even) inhomogeneous real-valued differential form in seven dimensions. In this... Read More about Fermions, differential forms and doubled geometry.

Gravity with more or less gauging (2018)
Journal Article
Gielen, S., de León Ardón, R., & Percacci, R. (2018). Gravity with more or less gauging. Classical and Quantum Gravity, 35(19), 195009. https://doi.org/10.1088/1361-6382/aadbd1

General relativity is usually formulated as a theory with gauge invariance under the diffeomorphism group, but there is a 'dilaton' formulation where it is in addition invariant under Weyl transformations, and a 'unimodular' formulation where it is o...

Network mechanisms underlying the role of oscillations in cognitive tasks (2018)
Journal Article
Schmidt, H., Avitabile, D., Montbrió, E., & Roxin, A. (2018). Network mechanisms underlying the role of oscillations in cognitive tasks. PLoS Computational Biology, 14(9), 1-24. https://doi.org/10.1371/journal.pcbi.1006430

Oscillatory activity robustly correlates with task demands during many cognitive tasks. However, not only are the network mechanisms underlying the generation of these rhythms poorly understood, but it is also still unknown to what extent they may pl...
