Lepton asymmetry from mixing and oscillations (2016)
Journal Article
Kartavtsev, A., Millington, P., & Vogel, H. (2016). Lepton asymmetry from mixing and oscillations. Journal of High Energy Physics, 2016(6), Article 66. https://doi.org/10.1007/JHEP06%282016%29066

We show how the two physically-distinct sources of CP-asymmetry relevant to scenarios of leptogenesis: (i) resonant mixing and (ii) oscillations between different flavours can be unambiguously identified within the Kadanoff-Baym formalism. These cont... Read More about Lepton asymmetry from mixing and oscillations.

Robustness of many-body localization in the presence of dissipation (2016)
Journal Article
Levi, E., Heyl, M., Lesanovsky, I., & Garrahan, J. P. (2016). Robustness of many-body localization in the presence of dissipation. Physical Review Letters, 116, Article 237203. https://doi.org/10.1103/PhysRevLett.116.237203

Many-body localization (MBL) has emerged as a novel paradigm for robust ergodicity breaking in closed quantum many-body systems. However, it is not yet clear to which extent MBL survives in the presence of dissipative processes induced by the couplin...

Multiple-stable anisotropic magnetoresistance memory in antiferromagnetic MnTe (2016)
Journal Article
Kriegner, D., Výborný, K., Olejnik, K., Reichlová, H., Novák, V., Marti, X., Gazquez, J., Saidl, V., Němec, P., Volobuev, V., Springholz, G., Holy, V., & Jungwirth, T. (in press). Multiple-stable anisotropic magnetoresistance memory in antiferromagnetic MnTe. Nature Communications, 7(11623), https://doi.org/10.1038/ncomms11623

Commercial magnetic memories rely on the bistability of ordered spins in ferromagnetic materials. Recently, experimental bistable memories have been realized using fully compensated antiferromagnetic metals. Here we demonstrate a multiple-stable memo...

Quantum confinement and photoresponsivity of β-In2Se3 nanosheets grown by physical vapour transport (2016)
Journal Article
Balakrishnan, N., Staddon, C. R., Smith, E. F., Stec, J., Gay, D., Mudd, G. W., Makarovsky, O., Kudrynskyi, Z. R., Kovalyuk, Z. D., Eaves, L., Patanè, A., & Beton, P. H. (in press).

We demonstrate that β-In2Se3 layers with thickness ranging from 2.8 – 100 nm can be grown on SiO2/Si, mica and graphite using a physical vapour transport method. The β-In2Se3 layers are chemically stable at room temperature and exhibit a blue-shift o...

MEG offers dynamic and spectral resolution for resting-state connectivity which is unavailable in fMRI. However, there are a wide range of available network estimation methods for MEG, and little in the way of existing guidance on which ones to emplo...

We present the first complete MCMC analysis of cosmological models with evolving cosmic (super)string networks, using the Unconnected Segment Model in the unequal-time correlator formalism. For ordinary cosmic string networks, we derive joint constra... Read More about CMB constraints on cosmic strings and superstrings.
