Spatial control of heavy-fermion superconductivity in CeIrIn5

Philip Johannes Walter Moll, Matthias Carsten Putzke, Maja Deborah Bachmann, Kent Robert Shirer

Although crystals of strongly correlated metals exhibit a diverse set of electronic ground states, few approaches exist for spatially modulating their properties. In this study, we demonstrate disorder-free control, on the micrometer scale, over the superc ...

Persistent antiferromagnetic order in heavily overdoped Ca1-xLaxFeAs2

László Forró, Henrik Moodysson Rønnow, Ivica Zivkovic, Ana Akrap, Philip Johannes Walter Moll, Sergiy Katrych, Edoardo Martino, Maja Deborah Bachmann

In the Ca1-xLaxFeAs2 (1 1 2) family of pnictide superconductors, we have investigated a highly overdoped composition (x = 0.56), prepared by a high-pressure, high-temperature synthesis. Magnetic measurements show an antiferromagnetic transition at T-N = 12 ...

Colossal mid-infrared bulk photovoltaic effect in a type-I Weyl semimetal

Xiangwei Huang, Philip Johannes Walter Moll, Weiyan Ni, Xu Yang

Broadband, efficient and fast conversion of light to electricity is crucial for sensing and clean energy. The bulk photovoltaic effect (BPVE) is a second-order nonlinear optical effect that intrinsically converts light into electrical current. Here, we dem ...

Super-geometric electron focusing on the hexagonal Fermi surface of PdCoO2

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

Geometric electron optics may be implemented in solids when electron transport is ballistic on the length scale of a device. Currently, this is realized mainly in 2D materials characterized by circular Fermi surfaces. Here we demonstrate that the nearly pe ...

Out-of-plane transport in ZrSiS and ZrSiSe microstructures

Philip Johannes Walter Moll, Maja Deborah Bachmann, Kent Robert Shirer

A recent class of topological nodal-line semimetals with the general formula MSiX (M = Zr, Hf and X = S, Se, Te) has attracted much experimental and theoretical interest due to their properties, particularly their large magnetoresistances and high carrier ...

Resonant torsion magnetometry in anisotropic quantum materials

Philip Johannes Walter Moll, Maja Deborah Bachmann, Kent Robert Shirer, Amelia Emily-Kay Estry

Unusual behavior in quantum materials commonly arises from their effective low-dimensional physics, reflecting the underlying anisotropy in the spin and charge degrees of freedom. Here we introduce the magnetotropic coefficient k = partial derivative F-2/p ...

Symmetry breakdown of electron emission in extreme ultraviolet photoionization of argon

Philip Johannes Walter Moll, Eugenio Ferrari, David Ferdinand Scholz

Short wavelength free-electron lasers (FELs), providing pulses of ultrahigh photon intensity, have revolutionized spectroscopy on ionic targets. Their exceptional photon flux enables multiple photon absorptions within a single femtosecond pulse, which in t ...
