Signatures of two gaps in the spin susceptibility of a cuprate superconductor
R. Zhou, I. Vinograd, M. Hirata +10
A major obstacle to understanding high-Tc cuprates is that superconductivity precludes observing normal-state properties at low temperatures. One prime example is the normal-state…
Hidden magnetism at the pseudogap critical point of a high temperature superconductor
Mehdi Frachet, Igor Vinograd, Rui Zhou +17
The mysterious pseudogap phase of cuprate superconductors ends at a critical hole doping level p* but the nature of the ground state below p* is still debated. Here, we show that t…
Detection of a Disorder-Induced Bose-Einstein Condensate in a Quantum Spin Material at High Magnetic Fields
A. Orlova, H. Mayaffre, S. Krämer +5
The coupled spin-1 chains material NiCl-4SC(NH) (DTN) doped with Br impurities is expected to be a perfect candidate for observing many-body localization at high magnet…
Spin susceptibility of charge ordered YBa2Cu3Oy across the upper critical field
R. Zhou, M. Hirata, T. Wu +9
The value of the upper critical field Hc2, a fundamental characteristic of the superconducting state, has been subject to strong controversy in high-Tc copper-oxides. Since the iss…
Dynamics of Bound Magnon Pairs in the Quasi-One-Dimensional Frustrated Magnet LiCuVO_4
Kazuhiro Nawa, Masashi Takigawa, Steffen Krämer +4
We report on the dynamics of the spin-1/2 quasi-one-dimensional frustrated magnet LiCuVO measured by nuclear spin relaxation in high magnetic fields 10--34 T, in which…
Observation of electronic bound states in charge-ordered YBaCuO
R. Zhou, M. Hirata, T. Wu +11
Observing how electronic states in solids react to a local symmetry breaking provides insight into their microscopic nature. A striking example is the formation of bound states whe…
Dichotomy between Attractive and Repulsive Tomonaga-Luttinger Liquids in Spin Ladders
M. Jeong, D. Schmidiger, H. Mayaffre +8
We present two methods to determine whether the interactions in a Tomonaga-Luttinger liquid (TLL) state of a spin- Heisenberg antiferromagnetic ladder are attractive or repuls…
Onset field for Fermi-surface reconstruction in the cuprate superconductor YBCO
G. Grissonnanche, F. Laliberte, S. Dufour-Beausejour +17
Quantum oscillations and negative Hall and Seebeck coefficients at low temperature and high magnetic field have shown the Fermi surface of underdoped cuprates to contain a small cl…
Evidence of Andreev bound states as a hallmark of the FFLO phase in -(BEDT-TTF)Cu(NCS)
H. Mayaffre, S. Kramer, M. Horvatić +4
Superconductivity is a quantum phenomena arising, in its simplest form, from pairing of fermions with opposite spin into a state with zero net momentum. Whether superconductivity c…
Hyperfine coupling and spin polarization in the bulk of the topological insulator BiSe
S. Mukhopadhyay, S. Krämer, H. Mayaffre +10
Nuclear magnetic resonance (NMR) and transport measurements have been performed at high magnetic fields and low temperatures in a series of -type BiSe crystals. In l…
Incipient charge order observed by NMR in the normal state of YBa2Cu3Oy
T. Wu, H. Mayaffre, S. Krämer +6
The pseudogap regime of high-temperature cuprates harbours diverse manifestations of electronic ordering whose exact nature and universality remain debated. Here, we show that the…
Emergence of charge order from the vortex state of a high temperature superconductor
T. Wu, H. Mayaffre, S. Kramer +8
Evidence is mounting that charge order competes with superconductivity in high Tc cuprates. Whether this has any relationship to the pairing mechanism is unknown since neither the…
Fermi Surface Reconstruction inside the Hidden Order Phase of URu2Si2 Probed by Thermoelectric Measurements
Alexandre Pourret, Alexandra Palacio-Morales, Steffen Kramer +5
We report thermoelectric measurements of the low carrier heavy fermion compound URu2Si2 at high fields up to 34T and at low temperatures down to 500mK. The field dependence of the…
Microscopic properties of the "pinwheel" kagome compound Rb_2Cu_3SnF_{12}
M. S. Grbić, S. Krämer, C. Berthier +4
Using Cu nuclear magnetic resonance (NMR) in magnetic fields up to 30 T we study the microscopic properties of the 12-site valence-bond-solid ground state in the "pinwhee…

Makoto Yoshida, Masashi Takigawa, Steffen Kramer +6
We report results of 51V NMR experiments on a high-quality powder sample of volborthite Cu3V2O7(OH)2/2H2O, a spin-1/2 Heisenberg antiferromagnet on a distorted kagome lattice. Foll…
Magnetic-field-induced charge-stripe order in the high temperature superconductor YBa2Cu3Oy
T. Wu, H. Mayaffre, S. Kramer +6
Electronic charges introduced in copper-oxide planes generate high-transition temperature superconductivity but, under special circumstances, they can also order into filaments cal…
