Role of a higher-dimensional interaction in stabilizing charge density waves in quasi-one-dimensional ${\mathrm{NbSe}}_{3}$ revealed by angle-resolved photoemission spectroscopy

Nicholson, Christopher W. ; Schwier, Eike Fabian ; Shimada, K. ; Berger, Helmuth ; Hoesch, M. ; Berthod, C. ; Monney, Claude

In: Physical Review B, 2020, vol. 101, no. 4, p. 045412

We revisit charge density wave (CDW) behavior in the archetypal quasi-one- dimensional (quasi-1D) material NbSe3 by high-resolution angle-resolved photoemission spectroscopy measurements utilizing a microfocused laser with a photon energy of 6.3 eV. We present a detailed view of the electronic structure of this complex multiband system and unambiguously resolve CDW gaps at the Fermi level ...

Mountain permafrost degradation documented through a network of permanent electrical resistivity tomography sites

Mollaret, Coline ; Hilbich, Christin ; Pellet, Cécile ; Flores-Orozco, Adrian ; Delaloye, Reynald ; Hauck, Christian

In: The Cryosphere, 2019, vol. 13, no. 10, p. 2557–2578

Mountain permafrost is sensitive to climate change and is expected to gradually degrade in response to the ongoing atmospheric warming trend. Long-term monitoring of the permafrost thermal state is a key task, but problematic where temperatures are close to 0 ∘C because the energy exchange is then dominantly related to latent heat effects associated with phase change (ice–water), rather...

Calibrated ice thickness estimate for all glaciers in Austria

Helfricht, Kay ; Huss, Matthias ; Fischer, Andrea ; Otto, Jan-Christoph

In: Frontiers in Earth Science, 2019, vol. 7, p. -

Knowledge on ice thickness distribution and total ice volume is a prerequisite for computing future glacier change for both glaciological and hydrological applications. Various ice thickness estimation methods have been developed but regional differences in fundamental model parameters are substantial. Parameters calibrated with measured data at specific points in time and space can vary when...
