Interplay between disorder and electronic correlations in compositionally complex alloys

László Forró, Jan Hugo Dil, Luka Ciric, Edoardo Martino, Xavier François Mettan, Trpimir Ivsic, Davor Tolj

Owing to their exceptional mechanical, electronic, and phononic transport properties, compositionally complex alloys, including high-entropy alloys, represent an important class of materials. However, the interplay between chemical disorder and electronic ...

Electron Glass Phase with Resilient Zhang-Rice Singlets in LiCu3O3

Rosario Scopelliti, László Forró, Henrik Moodysson Rønnow, Arnaud Magrez, Krunoslav Prsa, Simon Karl Moser, Paul Gregory Freeman, Jens Christian Johannsen, Gianmarco Gatti, Edoardo Martino

LiCu3O3 is an antiferromagnetic mixed valence cuprate where trilayers of edge -sharing Cu(II)O (3d9) are sandwiched in between planes of Cu(I) (3d10) ions, with Li stochastically substituting Cu(II). Angle resolved photoemission spectroscopy (ARPES) and de ...

Characterization of two electronic subsystems in cuprates through optical conductivity

Ana Akrap, Edoardo Martino, Neven Barisic

Understanding the physical properties of unconventional superconductors as well as of other correlated materials presents a formidable challenge. Their unusual evolution with doping, frequency, and temperature has frequently led to non-Fermi-liquid (non-FL ...

Synthesis of murunskite single crystals: A bridge between cuprates and pnictides

László Forró, Henrik Moodysson Rønnow, Ivica Zivkovic, Ana Akrap, Edoardo Martino, Konstantin Semeniuk, Trpimir Ivsic, Davor Tolj

Numerous contemporary investigations in condensed matter physics are devoted to high temperature (high-T-c) cuprate superconductors. Despite its unique effulgence among research subjects, the enigma of the high-T-c mechanism still persists. One way to adva ...

Acoustic-Pressure-Assisted Engineering of Aluminum Foams

László Forró, Jacim Jacimovic, Edoardo Martino, Xavier François Mettan

Shaping metals as a foam modulates their physical properties, enabling attractive applications where lightweight, low thermal conductivity, or acoustic isolation are desirable. Adjusting the size of the bubbles in the foams is particularly relevant for tar ...

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 ...

Radial Spin Texture of the Weyl Fermions in Chiral Tellurium

Majed Chergui, Henrik Moodysson Rønnow, Marco Grioni, Oleg Yazyev, Luc Testa, Daniel Gosalbez Martinez, Michele Puppin, Philippe Bugnon, Luca Moreschini, Alberto Crepaldi

Trigonal tellurium, a small-gap semiconductor with pronounced magneto-electric and magneto-optical responses, is among the simplest realizations of a chiral crystal. We have studied by spin- and angle-resolved photoelectron spectroscopy its unconventional ...

Preferential out-of-plane conduction and quasi-one-dimensional electronic states in layered 1T-TaS2

László Forró, Alla Arakcheeva, Luka Ciric, Helmuth Berger, Philip Johannes Walter Moll, Andrea Pisoni, Ana Akrap, Matthias Carsten Putzke, Edoardo Martino, Konstantin Semeniuk

Layered transition metal dichalcogenides (TMDs) are commonly classified as quasi-two-dimensional materials, meaning that their electronic structure closely resembles that of an individual layer, which results in resistivity anisotropies reaching thousands. ...

Electrons leave the flatland: out-of-plane charge dynamics in layered materials

Edoardo Martino

The goal of this thesis is to explore the "neglected" third dimension of layered materials, by studying the interlayer charge dynamics through dc conductivity, optical spectroscopy and ab-initio calculations. This project was designed to respond to the gro ...

Structural Phase Transition and Bandgap Control through Mechanical Deformation in Layered Semiconductors 1T-ZrX2 (X = S, Se)

Oleg Yazyev, Helmuth Berger, Ana Akrap, Michele Pizzochero, Edoardo Martino, Kristians Cernevics, Konstantin Semeniuk

Applying elastic deformation can tune a material's physical properties locally and reversibly. Spatially modulated lattice deformation can create a bandgap gradient, favoring photogenerated charge separation and collection in optoelectronic devices. These ...
