Hall response of locally correlated two-dimensional electrons at low density
Giacomo Morpurgo, Louk Rademaker, Christophe Berthod +1
We study the Hall constant in a homogeneous two-dimensional fluid of correlated electrons immersed in a perpendicular magnetic field, with special focus on the regime of low carrie…
Theory of spin-polarized high-resolution electron energy loss spectroscopy from nonmagnetic surfaces with a large spin-orbit coupling
Khalil Zakeri, Christophe Berthod
The scattering theory of low-energy (slow) electrons has been developed by Evans and Mills [Phys. Rev. B 5, 4126 (1972)]. The formalism is merely based on the electrostatic Coulomb…
Reconciling scaling of the optical conductivity of cuprate superconductors with Planckian resistivity and specific heat
B. Michon, C. Berthod, C. W. Rischau +7
Materials tuned to a quantum critical point display universal scaling properties as a function of temperature and frequency . A long-standing puzzle regarding cuprate superc…
High-resolution photoemission on Sr2RuO4 reveals correlation-enhanced effective spin-orbit coupling and dominantly local self-energies
A. Tamai, M. Zingl, E. Rozbicki +17
We explore the interplay of electron-electron correlations and spin-orbit coupling in the model Fermi liquid Sr2RuO4 using laser-based angle-resolved photoemission spectroscopy. Ou…
Dimensional Crossover in a Charge Density Wave Material Probed by Angle-Resolved Photoemission Spectroscopy
Christopher W. Nicholson, Christophe Berthod, Michele Puppin +4
High-resolution angle-resolved photoemission spectroscopy (ARPES) data reveal evidence of a crossover from one-dimensional (1D) to three-dimensional (3D) behavior in the prototypic…
Collapse of the Mott gap and emergence of a nodal liquid in lightly doped SrIrO
A. de la Torre, S. McKeown Walker, F. Y. Bruno +13
Superconductivity in underdoped cuprates emerges from an unusual electronic state characterised by nodal quasiparticles and an antinodal pseudogap. The relation between this state…
Large modulation of the Shubnikov-de Haas oscillations by the Rashba interaction at the LaAlO/SrTiO interface
A. Fête, S. Gariglio, C. Berthod +4
We investigate the 2-dimensional Fermi surface of high-mobility LaAlO/SrTiO interfaces using Shubnikov-de Haas oscillations. Our analysis of the oscillation pattern undersc…
Optical Response of SrRuO Reveals Universal Fermi-liquid Scaling and Quasiparticles Beyond Landau Theory
D. Stricker, J. Mravlje, C. Berthod +4
We report optical measurements demonstrating that the low-energy relaxation rate () of the conduction electrons in SrRuO obeys scaling relations for its frequency (…
Non-Drude universal scaling laws for the optical response of local Fermi liquids
Christophe Berthod, Jernej Mravlje, Xiaoyu Deng +3
We investigate the frequency and temperature dependence of the low-energy electron dynamics in a Landau Fermi liquid with a local self-energy. We show that the frequency and temper…
Hall effect on the triangular lattice
Gladys León, Christophe Berthod, Thierry Giamarchi +1
We investigate the high frequency Hall effect on a two-dimensional triangular lattice with nearest-neighbor hopping and a local Hubbard interaction. The complete temperature and do…
Hall effect in strongly correlated low dimensional systems
G. León, C. Berthod, T. Giamarchi
We investigate the Hall effect in a quasi one-dimensional system made of weakly coupled Luttinger Liquids at half filling. Using a memory function approach, we compute the Hall coe…
Breakup of the Fermi surface near the Mott transition in low-dimensional systems
C. Berthod, T. Giamarchi, S. Biermann +1
We investigate the Mott transition in weakly-coupled one-dimensional (1d) fermionic chains. Using a generalization of Dynamic Mean Field Theory, we show that the Mott gap is suppre…
