{"title":"Resolving the Negative Effective Neutrino Mass Parameter with Cosmic Birefringence","authors":"Toshiya Namikawa","doi":"10.1103/qgnn-6hsf","DOIUrl":"https://doi.org/10.1103/qgnn-6hsf","url":null,"abstract":"The recent measurement of baryonic acoustic oscillations by the Dark Energy Spectroscopic Instrument reveals a mild tension with observations of the cosmic microwave background (CMB) within the standard Λ</a:mi></a:math> cold dark matter (<d:math xmlns:d=\"http://www.w3.org/1998/Math/MathML\" display=\"inline\"><d:mi mathvariant=\"normal\">Λ</d:mi><d:mi>CDM</d:mi></d:math>) cosmological model. This discrepancy leads to a preference for a total neutrino mass that is lower than the minimum value inferred from neutrino oscillation experiments. Alternatively, this tension can be eased within <g:math xmlns:g=\"http://www.w3.org/1998/Math/MathML\" display=\"inline\"><g:mi mathvariant=\"normal\">Λ</g:mi><g:mi>CDM</g:mi></g:math> by assuming a higher optical depth (<j:math xmlns:j=\"http://www.w3.org/1998/Math/MathML\" display=\"inline\"><j:mi>τ</j:mi><j:mo>≃</j:mo><j:mn>0.09</j:mn></j:math>), but such a value conflicts with large-scale CMB polarization data. We point out that cosmic birefringence, as suggested by recent Planck reanalyses, resolves this discrepancy if the birefringence angle varies significantly during reionization. Specifically, we consider the fact that the measured cosmic birefringence angle <l:math xmlns:l=\"http://www.w3.org/1998/Math/MathML\" display=\"inline\"><l:mrow><l:msub><l:mrow><l:mi>β</l:mi></l:mrow><l:mrow><l:mn>0</l:mn></l:mrow></l:msub><l:mo>=</l:mo><l:mn>0.34</l:mn><l:mo>±</l:mo><l:mn>0.09</l:mn><l:mo stretchy=\"false\">(</l:mo><l:mn>1</l:mn><l:mi>σ</l:mi><l:mo stretchy=\"false\">)</l:mo><l:mtext> </l:mtext><l:mtext> </l:mtext><l:mi>deg</l:mi></l:mrow></l:math> has the phase ambiguity, i.e., the measured rotation angle is described by <p:math xmlns:p=\"http://www.w3.org/1998/Math/MathML\" display=\"inline\"><p:mrow><p:mi>β</p:mi><p:mo>=</p:mo><p:msub><p:mrow><p:mi>β</p:mi></p:mrow><p:mrow><p:mn>0</p:mn></p:mrow></p:msub><p:mo>+</p:mo><p:mn>180</p:mn><p:mi>n</p:mi><p:mtext> </p:mtext><p:mtext> </p:mtext><p:mi>deg</p:mi></p:mrow></p:math> (<r:math xmlns:r=\"http://www.w3.org/1998/Math/MathML\" display=\"inline\"><r:mi>n</r:mi><r:mo>∈</r:mo><r:mi mathvariant=\"double-struck\">Z</r:mi></r:math>).

In particular, electrically detected magnetic resonance (EDMR) probes directly the changes in charge transport properties that are sensitive to magnetic resonance excitation. Here, we present a systematic study of continuous-wave EDMR on conjugated polymer field-effect transistors (FETs) that can be operated in both unipolar as well as ambipolar regimes. We show that, in addition to a narrow, electron-hole recombination-induced EDMR signal that can only be detected in the ambipolar regime, there is also a broad EDMR signal when devices are operated in both unipolar and ambipolar regions. We attribute this signal to a spin blockade mechanism induced when mobile carriers encounter trapped charges along the charge transport percolation pathways and study its dependence on biasing conditions and temperature. The spin-blockade EDMR signature is also observed in conjugated polymer FETs that exhibit only unipolar operation. Our findings show that EDMR provides a powerful technique to study the role of spin blockade and bipolaron formation on the charge transport properties of a wide range of conjugated polymers.","PeriodicalId":20069,"journal":{"name":"Physical review letters","volume":"10 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2025-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145295831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
