Observation of the non-linear Meissner effect

Matthias Carsten Putzke

A long-standing theoretical prediction is that in clean, nodal unconventional superconductors the magnetic penetration depth lambda, at zero temperature, varies linearly with magnetic field. This non-linear Meissner effect is an equally important manifesta ...

Three-dimensional Fermi surfaces from charge order in layered CsV3Sb5

Philip Johannes Walter Moll, Matthias Carsten Putzke, Chunyu Guo, Yi-Chiang Sun, Xiangwei Huang

The cascade of electronic phases in CsV3Sb5 raises the prospect to disentangle their mutual interactions in a clean, strongly interacting kagome lattice. When the kagome planes are stacked into a crystal, its electronic dimensionality encodes how much of t ...

Low-symmetry nonlocal transport in microstructured squares of delafossite metals

Matthias Carsten Putzke

Intense work studying the ballistic regime of electron transport in two-dimensional systems based on semiconductors and graphene had been thought to have established most of the key experimental facts of the field. In recent years, however, additional form ...

Temperature dependence of quantum oscillations from non-parabolic dispersions

Oleg Yazyev, Quansheng Wu, Shengnan Zhang, Matthias Carsten Putzke, Chunyu Guo, Amelia Emily-Kay Estry

A versatile methodology to detect topological quasiparticles by transport measurements remains an open problem. Here, the authors propose and experimentally observe the temperature dependence of the quantum oscillation frequency as a signature of non-trivi ...

Non-linear Shubnikov-de Haas oscillations in the self-heating regime

Philip Johannes Walter Moll, Matthias Carsten Putzke, Chunyu Guo, Xiangwei Huang, Jonas De Jesus Diaz Gomez

We demonstrate a non-linear measurement scheme of the Shubnikov-de Haas effect based on Joule self-heating that builds on ideas of the 3 ?-method used in thin films. While the temperature dependence of the resistance, R(T), of clean metals at low temperatu ...

Sondheimer oscillations as a probe of non-ohmic flow in WP2 crystals

Philip Johannes Walter Moll, Matthias Carsten Putzke, Chunyu Guo, Yi-Chiang Sun, Jonas De Jesus Diaz Gomez, Maarten Ruud van Delft, Jacopo Oswald

As conductors in electronic applications shrink, microscopic conduction processes lead to strong deviations from Ohm's law. Depending on the length scales of momentum conserving (l(MC)) and relaxing (l(MR)) electron scattering, and the device size (d), cur ...

Unidirectional Kondo scattering in layered NbS2

László Forró, Oleg Yazyev, Christoph Koch, Quansheng Wu, Shengnan Zhang, Helmuth Berger, Philip Johannes Walter Moll, Matthias Carsten Putzke, Edoardo Martino, Konstantin Semeniuk

Crystalline defects can modify quantum interactions in solids, causing unintuitive, even favourable, properties such as quantum Hall effect or superconducting vortex pinning. Here we present another example of this notion-an unexpected unidirectional Kondo ...

Evidence of a coupled electron-phonon liquid in NbGe2

Mathieu François Padlewski, Matthias Carsten Putzke, Philip Johannes Walter Moll, Hao Yang

Whereas electron-phonon scattering relaxes the electron's momentum in metals, a perpetual exchange of momentum between phonons and electrons may conserve total momentum and lead to a coupled electron-phonon liquid. Such a phase of matter could be a platfor ...

Magnetic electron collimation in three-dimensional semi-metals

Philip Johannes Walter Moll, Matthias Carsten Putzke, Chunyu Guo, Xiangwei Huang, Jonas De Jesus Diaz Gomez

While electrons moving perpendicular to a magnetic field are confined to cyclotron orbits, they can move freely parallel to the field. This simple fact leads to complex current flow in clean, low carrier density semi-metals, such as long-ranged current jet ...

h/e oscillations in interlayer transport of delafossites

Philip Johannes Walter Moll, Matthias Carsten Putzke, Maja Deborah Bachmann

Microstructures can be carefully designed to reveal the quantum phase of the wave-like nature of electrons in a metal. Here, we report phase-coherent oscillations of out-of-plane magnetoresistance in the layered delafossites PdCoO2 and PtCoO2. The oscillat ...
