Electron-phonon coupling across the TMD/hBN van der Waals interface
G. Gatti, C. Berthod, J. Issing +18
Many-body interactions can couple electronic states in one layer with collective excitations in the adjacent layer, providing a route to tailor properties of heterostructures. Howe…
Origin of the magnetic ground state of TbIrO
Y. Alexanian, E. Lhotel, J. Robert +10
Magnetic-rare-earth pyrochlore iridates exhibit a rich variety of unconventional phases, driven by the complex interactions within and between the rare-earth and the iridium sublat…
Non-Fermi liquid quasiparticles in strain-tuned Sr2RuO4
A. Hunter, C. Putzke, F. B. Kugler +23
Interacting electrons can form metallic states beyond the Fermi liquid paradigm, a conceptual frontier of many-body physics mainly explored via bulk thermodynamics and transport. I…
Evidence for spin liquid behavior in the frustrated three-dimensional Heisenberg garnet NaCaCu(VO)
Y. Alexanian, R. Kumar, H. Zeroual +10
Three-dimensional quantum spin liquids have remained elusive, hindered by reduced quantum fluctuations from larger lattice connectivity inherent to high-dimensional systems. Here,…
Nature of metallic and insulating domains in the CDW system 1T-TaSe2
M. Straub, F. Petocchi, C. Witteveen +12
We study the electronic structure of bulk 1T-TaSe in the charge density wave phase at low temperature. Our spatially and angle resolved photoemission (ARPES) data show insulati…
Fermi surface and pseudogap in highly doped SrIrO
Y. Alexanian, A. de la Torre, S. McKweon Walker +18
The fate of the Fermi surface in bulk electron-doped SrIrO remains elusive, as does the origin and extension of its pseudogap phase. Here, we use high-resolution angle-…
Exploring possible magnetic monopoles-induced magneto-electricity in spin ices
Y. Alexanian, J. Saugnier, C. Decorse +7
The possibilities of combining several degrees of freedom inside a unique material have recently been highlighted in their dynamics and proposed as information carriers in quantum…
The fate of quasiparticles at high-temperature
A. Hunter, S. Beck, E. Cappelli +17
We study the temperature evolution of quasiparticles in the correlated metal SrRuO. Our angle resolved photoemission data show that quasiparticles persist up to temperature…
Collective magnetic state induced by charge disorder in the non-Kramers rare-earth pyrochlore TbScNbO
Y. Alexanian, E. Lhotel, R. Ballou +15
Geometrical frustration, as in pyrochlore lattices made of corner-sharing tetrahedra, precludes the onset of conventional magnetic ordering, enabling the stabilization of fluctuati…
Vibronic collapse of ordered quadrupolar ice in the pyrochore magnet TbTiO
Yann Alexanian, Julien Robert, Virginie Simonet +8
While the spin liquid state in the frustrated pyrochlore TbTiO has been studied both experimentally and theoretically for more than two decades, no definite…
Terahertz Magneto-optical investigation of quadrupolar spin-lattice effects in magnetically frustrated Tb2Ti2O7
K. Amelin, Y. Alexanian, U. Nagel +9
The significance of spin-lattice coupling in the phase diagram of the quantum spin-icepyrochlore Tb2Ti2O7 has been a topic of debate for some time. Here, we focus on the aspect of…
