In this work, we describe the phosphide Ce6Ni6P17, where the Ce+3 ions accommodate in a body-centered cubic lattice of Ce6 regular octahedra. From measurements of magnetization, specific heat, and resistivity, we determine a rich phase diagram as a function of temperature and magnetic field in which different magnetic phases are found. Besides clear evidence of magnetic frustration is obtained from entropy analysis. At zero field, a second-order antiferromagnetic transition occurs at TN1≈1 K followed by a first-order transition at TN2≈0.45 K. With magnetic field new magnetic phases appear, including a weakly first-order transition which ends in a classical critical point and a third magnetic phase. We also study the exact solution of the spin-1/2 Heisenberg model in an octahedron which allows us a qualitative understanding of the phase diagram and compare with the experimental results.","lang":"eng"}],"month":"02","intvolume":" 109","scopus_import":"1"},{"quality_controlled":"1","publisher":"Elsevier","oa":1,"acknowledgement":"The Ge project received funding from the European Union's Horizon Europe programme under the Grant Agreement 101069515 – IGNITE.

The assessment of the layer and the interface qualities for a buried strained Ge layer embedded in Si0.3Ge0.7 layers is reported. The XRD reciprocal space mapping confirmed that the reduction of the growth temperature enables the 2-dimensional growth of the Ge layer fully strained with respect to the Si0.3Ge0.7. Nevertheless, dislocations at the top and/or bottom interface of the Ge layer were observed by means of electron channeling contrast imaging, suggesting the importance of the careful dislocation assessment. The interface abruptness does not depend on the selection of the precursor gases, but it is strongly influenced by the growth temperature which affects the coverage of the surface H-passivation. The mobility of 2.7 × 105 cm2/Vs is promising, while the low percolation density of 3 × 1010 /cm2 measured with a Hall-bar device at 7 K illustrates the high quality of the heterostructure thanks to the high Si0.3Ge0.7 SRB quality."}],"oa_version":"Published Version","issue":"5","volume":174,"publication_identifier":{"issn":["1369-8001"]},"publication_status":"epub_ahead","language":[{"iso":"eng"}],"type":"journal_article","article_type":"original","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"status":"public","keyword":["Mechanical Engineering","Mechanics of Materials","Condensed Matter Physics","General Materials Science"],"_id":"15018","department":[{"_id":"GeKa"},{"_id":"NanoFab"}],"date_updated":"2024-02-26T10:36:35Z","ddc":["530"]},{"title":"How to prune your language model: Recovering accuracy on the \"Sparsity May Cry\" benchmark","external_id":{"arxiv":["2312.13547"]},"article_processing_charge":"No","author":[{"id":"47beb3a5-07b5-11eb-9b87-b108ec578218","first_name":"Eldar","last_name":"Kurtic","full_name":"Kurtic, Eldar"},{"last_name":"Hoefler","full_name":"Hoefler, Torsten","first_name":"Torsten"},{"id":"4A899BFC-F248-11E8-B48F-1D18A9856A87","first_name":"Dan-Adrian","orcid":"0000-0003-3650-940X","full_name":"Alistarh, Dan-Adrian","last_name":"Alistarh"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"mla":"Kurtic, Eldar, et al. “How to Prune Your Language Model: Recovering Accuracy on the ‘Sparsity May Cry’ Benchmark.” Proceedings of Machine Learning Research, vol. 234, ML Research Press, 2024, pp. 542–53.","ama":"Kurtic E, Hoefler T, Alistarh D-A.

The recent “Sparsity May Cry” (SMC) benchmark put into question the validity of all existing methods, exhibiting a more complex setup where many known pruning methods appear to fail. We revisit the question of accurate BERT-pruning during fine-tuning on downstream datasets, and propose a set of general guidelines for successful pruning, even on the challenging SMC benchmark. First, we perform a cost-vs-benefits analysis of pruning model components, such as the embeddings and the classification head; second, we provide a simple-yet-general way of scaling training, sparsification and learning rate schedules relative to the desired target sparsity; finally, we investigate the importance of proper parametrization for Knowledge Distillation in the context of LLMs. Our simple insights lead to state-of-the-art results, both on classic BERT-pruning benchmarks, as well as on the SMC benchmark, showing that even classic gradual magnitude pruning (GMP) can yield competitive results, with the right approach."}],"volume":234,"language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"eissn":["2640-3498"]}},{"project":[{"name":"IST-BRIDGE: International postdoctoral program","grant_number":"101034413","_id":"fc2ed2f7-9c52-11eb-aca3-c01059dda49c","call_identifier":"H2020"}],"article_number":"064503","title":"Correlation-induced viscous dissipation in concentrated electrolytes","article_processing_charge":"Yes (in subscription journal)","external_id":{"arxiv":["2311.11784"],"pmid":["38349632"]},"author":[{"first_name":"Paul","id":"48c58128-57b0-11ee-9095-dc28fd97fc1d","orcid":"0000-0002-5728-9189","full_name":"Robin, Paul","last_name":"Robin"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"ista":"Robin P. 2024.

The effects of these correlations on the solvent itself remain, however, much less clear. In particular, the addition of salt has been consistently reported to affect the solution’s viscosity, but most modeling attempts fail to reproduce experimental data even at moderate salt concentrations. Here, we use an approach based on stochastic density functional theory, which accurately captures charge fluctuations and correlations. We derive a simple analytical expression for the viscosity correction in concentrated electrolytes, by directly linking it to the liquid’s structure factor. Our prediction compares quantitatively to experimental data at all temperatures and all salt concentrations up to the saturation limit. This universal link between the microscopic structure and viscosity allows us to shed light on the nanoscale dynamics of water and ions under highly concentrated and correlated conditions."}],"ec_funded":1,"issue":"6","volume":160,"language":[{"iso":"eng"}],"file":[{"creator":"dernst","date_updated":"2024-02-27T08:12:52Z","file_size":5452738,"date_created":"2024-02-27T08:12:52Z","file_name":"2024_JourChemicalPhysics_Robin.pdf","access_level":"open_access","relation":"main_file","content_type":"application/pdf","file_id":"15034","checksum":"0a5e0ae70849bce674466fc054390ec0","success":1}],"publication_status":"published","publication_identifier":{"eissn":["1089-7690"],"issn":["0021-9606"]}},{"abstract":[{"text":"We consider quadratic forms of deterministic matrices A evaluated at the random eigenvectors of a large N×N GOE or GUE matrix, or equivalently evaluated at the columns of a Haar-orthogonal or Haar-unitary random matrix.
