Optimum inhomogeneity of local lattice distortions in La2CuO4+y
Nicola Poccia,Nicola Poccia,Alessandro Ricci,Gaetano Campi,Michela Fratini,Alessandro Puri,D. Di Gioacchino,Augusto Marcelli,Michael Reynolds,Manfred Burghammer,Naurang L. Saini,Gabriel Aeppli,Antonio Bianconi,Antonio Bianconi +13 more
TL;DR: Scanning X-ray microdiffraction is used to show that for La2CuO4+y, the glue regions contain incommensurate modulated local lattice distortions, whose spatial extent is most pronounced for the best superconducting samples.
Journal ArticleDOI
Axion Search with a Quantum-Limited Ferromagnetic Haloscope
N. Crescini,D. Alesini,Caterina Braggio,Giovanni Carugno,D. D'Agostino,D. Di Gioacchino,Paolo Falferi,U. Gambardella,Claudio Gatti,G. Iannone,Carlo Ligi,A. Lombardi,Antonello Ortolan,R. Pengo,Giuseppe Ruoso,L. Taffarello +15 more
TL;DR: The scientific run of the ferromagnetic axion haloscope resulted in the best limit on dark matter axions to electron coupling constant in a frequency span of about 120 MHz, corresponding to the axion-mass range 42.4-43.1 μeV.
Journal ArticleDOI

Lombardi,Renato Mezzena,Antonello Ortolan,R. Pengo,Nicola Pompeo,A. Rettaroli,Giuseppe Ruoso,Enrico Silva,Clive C. Speake,L. Taffarello,S. Tocci +24 more
TL;DR: In this paper, the authors presented the result of a search for galactic axions using a haloscope based on a $36\,\mbox{cm}^3$ NbTi superconducting cavity.
Journal ArticleDOI
Search for invisible axion dark matter of mass m a = 43 μ eV with the QUAX– a γ experiment
D. Alesini,Caterina Braggio,Giovanni Carugno,N. Crescini,D. D'Agostino,D. Di Gioacchino,R. Di Vora,Paolo Falferi,Umberto Gambardella,Claudio Gatti,G. Iannone,Carlo Ligi,A. Lombardi,G. Maccarrone,Antonello Ortolan,R. Pengo,A. Rettaroli,Giuseppe Ruoso,L. Taffarello,S. Tocci +19 more
TL;DR: A haloscope of the QUAX experiment composed of an oxygen-free high thermal conductivity-Cu cavity inside an 8.1 T magnet and cooled to the standard quantum limit was put into operation for the search of galactic axion as discussed by the authors.
Journal ArticleDOI
Operation of a ferromagnetic axion haloscope at $$m_a=58\,\upmu \mathrm {eV}$$ m a = 58 μ eV

TL;DR: In this paper, a prototype ferromagnetic haloscope is described, with a sensitivity limited by thermal fluctuations and receiver noise, which is able to set an upper limit on the coupling constant of DFSZ axions to electrons at 95% C.L.
