Journal ArticleDOI
Test of relativistic time dilation with fast optical atomic clocks at different velocities
S. Reinhardt,Guido Saathoff,Henrik Buhr,Lars A. Carlson,Andreas Wolf,Dirk Schwalm,Sergei Karpuk,C. Novotny,G. Huber,Marcus Zimmermann,Ronald Holzwarth,Thomas Udem,Theodor W. Hänsch,Gerald Gwinner +13 more
TL;DR: In this article, the authors report on a method, based on fast optical atomic clocks with large, but different Lorentz boosts, that tests relativistic time dilation with unprecedented precision.
Journal ArticleDOI
Improved Test of Time Dilation in Special Relativity
Guido Saathoff,Sergei Karpuk,U. Eisenbarth,G. Huber,S. Krohn,R. Muñoz Horta,S. Reinhardt,Dirk Schwalm,Alexander Wolf,Gerald Gwinner +9 more
TL;DR: An improved test of time dilation in special relativity has been performed using laser spectroscopy on fast ions at the heavy-ion storage-ring TSR in Heidelberg, confirming the relativistic Doppler formula and setting a new limit of 2.2 x 10(-7).
Journal ArticleDOI
Ultra-sensitive magnetometry based on free precession of nuclear spins
C. Gemmel,Werner Heil,Sergei Karpuk,K. Lenz,Ch. Ludwig,Yu. Sobolev,K. Tullney,Martin Burghoff,W. Kilian,S. Knappe-Grüneberg,Wolfgang Müller,Allard Schnabel,Frank Seifert,Lutz Trahms,St. Baeßler +14 more
TL;DR: In this paper, a low-field magnetometer based on the detection of free spin precession of gaseous, nuclear polarized 3He or 129Xe samples with a SQUID as magnetic flux detector is presented.
Journal ArticleDOI
Test of Time Dilation Using Stored Li + Ions as Clocks at Relativistic Speed
B. Botermann,Dennis Bing,Christopher Geppert,Gerald Gwinner,Theodor W. Hänsch,G. Huber,Sergei Karpuk,A. Krieger,T. Kuhl,Wilfried Nörtershäuser,Wilfried Nörtershäuser,C. Novotny,S. Reinhardt,Rodolfo Sánchez,Dirk Schwalm,Thomas Stöhlker,Andreas Wolf,Guido Saathoff +17 more
TL;DR: The concluding result from an Ives-Stilwell-type time dilation experiment using 7Li+ ions confined at a velocity of β=v/c=0.338 in the storage ring ESR at Darmstadt is verified and interpreted within Lorentz invariance violating test theories.
Journal ArticleDOI
Spin clocks: Probing fundamental symmetries in nature
Werner Heil,C. Gemmel,Sergei Karpuk,Yuri Sobolev,K. Tullney,F. Allmendinger,Ulrich Schmidt,Martin Burghoff,W. Kilian,S. Knappe-Grüneberg,Allard Schnabel,Frank Seifert,Lutz Trahms +12 more
TL;DR: In this paper, the free precession of co-located 3He/129Xe nuclear spins (clock comparison) is used as ultra-sensitive probe for non-magnetic spin interactions, since the magnetic dipole interaction (Zeeman-term) drops out in the weighted frequency difference, i.e., Δω = ωHe- γHe/γXe·ωXe of the respective Larmor frequencies.
