Conduction band structure and ultrafast dynamics of ferroelectric α−GeTe(111)

American Physical Society (APS)2025

Altermagnets as a new class of functional materials

Altermagnets are characterized by non-relativistic alternating spin splitting in the band structure and collinear compensated magnetic moments in real space. They combine the advantages of ferromagnetic and antiferromagnetic order, exhibiting time-reversal ...

Duality and degeneracy lifting in two-dimensional electron liquids on SrTiO3(001)

Jan Hugo Dil, Fei Guo

Two-dimensional electron liquids (2DELs) have increasing technological relevance for ultrafast electronics and spintronics, yet significant gaps in their fundamental understanding are exemplified on the prototypical SrTiO3. We correlate the exact SrTiO3(00 ...

Weyl metallic state induced by helical magnetic order

Henrik Moodysson Rønnow, Ivica Zivkovic, Jan Hugo Dil, Jian Rui Soh, Xupeng Yang

In the rapidly expanding field of topological materials there is growing interest in systems whose topological electronic band features can be induced or controlled by magnetism. Magnetic Weyl semimetals, which contain linear band crossings near the Fermi ...

Nanoscale imaging and control of altermagnetism in MnTe

Jan Hugo Dil

Nanoscale detection and control of the magnetic order underpins a spectrum of condensed-matter research and device functionalities involving magnetism. The key principle involved is the breaking of time-reversal symmetry, which in ferromagnets is generated ...

Magneto-optical response of the magnetic semiconductors EuCd2X2 (X =P, As, Sb)

Jan Hugo Dil, Ivica Zivkovic, Michele Puppin, Fei Guo

In this study, we identify EuCd2X2 (for X = P, As, Sb) as a series of magnetic semiconductors. We examine how the band gap of the series responds to X changing from phosphorus (P), to arsenic (As), and finally antimony (Sb). We characterize the samples usi ...

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 ...

Altermagnetic lifting of Kramers spin degeneracy

Jan Hugo Dil

Lifted Kramers spin degeneracy (LKSD) has been among the central topics of condensed-matter physics since the dawn of the band theory of solids. It underpins established practical applications as well as current frontier research, ranging from magnetic-mem ...

Real-and reciprocal space characterization of the three-dimensional charge density wave in quasi-one-dimensional CuTe

Arnaud Magrez, Jan Hugo Dil, Michele Puppin, Fei Guo

Low-dimensional materials are susceptible to electronic instabilities such as charge density waves (CDWs), originating from a divergence in the Lindhard electron response function, combined with a finite electron-phonon coupling strength. In this paper, we ...

Weyl spin-momentum locking in a chiral topological semimetal

Jan Hugo Dil

Spin-orbit coupling in noncentrosymmetric crystals leads to spin-momentum locking - a directional relationship between an electron's spin angular momentum and its linear momentum. Isotropic orthogonal Rashba spin-momentum locking has been studied for decad ...
