Strain and Temperature Dependence of the Electronic Structure of Sr2RuO4 Investigated by ARPES
Andrew Scott Hunter

Thèse (2023)

In its normal state, Sr2RuO4 is a prototypical Fermi liquid below ∼ 25 K. At ∼ 1.5 K it undergoes a superconducting transition, but it has long remained challenging to determine the symmetry or order parameter of the superconducting state. Recent experiments have shown…

Céline Lichtensteiger, Chia-Ping Su, Iaroslav Gaponenko, Marios Hadjimichael, Ludovica Tovaglieri, Patrycja Paruch, Alexandre Gloter and Jean-Marc Triscone

APL materials 11 10, 101110 (2023)

We investigate nanoscale domain engineering via epitaxial coupling in a set of SrRuO3/PbTiO3/SrRuO3 heterostructures epitaxially grown on (110)o-oriented DyScO3 substrates. The SrRuO3 layer thickness is kept at 55 unit cells, whereas the PbTiO3 layer is grown to thicknesses of 23, 45, and 90 unit…

Multiple antiferromagnetic phases and magnetic anisotropy in exfoliated CrBr3 multilayers
Fengrui Yao, Volodymyr Multian, Zhe Wang, Nicolas Ubrig, Jérémie Teyssier, Fan Wu, Enrico Giannini, Marco Gibertini, Ignacio Gutierrez Lezama and Alberto Morpurgo

Nature communications 14 1, 4969 (2023)

In twisted two-dimensional (2D) magnets, the stacking dependence of the magnetic exchange interaction can lead to regions of ferromagnetic and antiferromagnetic interlayer order, separated by non-collinear, skyrmion-like spin textures. Recent experimental searches for these textures have focused on …

Towards a muon collider

European physical journal. C, Particles and fields 83 9, 864 (2023)

A muon collider would enable the big jump ahead in energy reach that is needed for a fruitful exploration of fundamental interactions. The challenges of producing muon collisions at high luminosity and 10 TeV centre of mass energy are being investigated by the recently-formed International Muon…

Twist-Angle-Dependent Electronic Properties of Exfoliated Single Layer MoS2 on Au(111)
Ishita Pushkarna, Arpad Pasztor and Christoph Renner

Nano letters, 3c02804 (2023)

Synthetic materials and heterostructures obtained by the controlled stacking of exfoliated monolayers are emerging as attractive functional materials owing to their highly tunable properties. We present a detailed scanning tunneling microscopy and spectroscopy study of single layer…

Impact of deoxygenation/reoxygenation processes on the superconducting properties of commercial coated conductors
Pablo Cayado Llosa, Marco Bonura, Celia Lucas Esparseil, Enora Saule, Hannes Rijckaert, Tommaso Bagni, Konstantina Konstantopoulou, Matteo Alessandrini and Carmine Senatore

Scientific reports 13 1, 16917 (2023)

We report the evolution of the superconducting properties of a commercial coated conductor during deoxygenation and reoxygenation processes. By analyzing the changes on the critical temperature, T c , and critical current density, J c , at 4 and 77 K, we have identified the…

Designing spin and orbital sources of Berry curvature at oxide interfaces
Edouard Lesne, Yildiz G. Saǧlam, Raffaele Battilomo, Maria Teresa Mercaldo, Thierry C. van Thiel, Ulderico Filippozzi, Canio Noce, Mario Cuoco, Gary A. Steele, Carmine Ortix and Andrea Caviglia

Nature materials (2023)

Quantum materials can display physical phenomena rooted in the geometry of electronic wavefunctions. The corresponding geometric tensor is characterized by an emergent field known as the Berry curvature (BC). Large BCs typically arise when electronic states with different spin, orbital or…

Orbital design of Berry curvature: pinch points and giant dipoles induced by crystal fields
Maria Teresa Mercaldo, Canio Noce, Andrea Caviglia, Mario Cuoco and Carmine Ortix

npj quantum materials 8 12 (2023)

The Berry curvature (BC)—a quantity encoding the geometric properties of the electronic wavefunctions in a solid—is at the heart of different Hall-like transport phenomena, including the anomalous Hall and the non-linear Hall and Nernst effects. In non-magnetic quantum materials with acentric…
