Non-collinear Altermagnetic Phases in the Mott Insulator NiS
Mengli Hu, Mikel I. Iraola, Paul McClarty +2
Altermagnets (AMs) constitute a novel family of magnetic materials characterized by the absence of net magnetization and the presence of spin-polarized band structures. Where…
Characterizing Mott Insulators in the Interacting One-Body Picture
Theo N. Dionne, Santiago Villodre, Mikel Iraola +1
The one-body picture underlies our understanding of weakly interacting solids but breaks down in strongly correlated systems. We develop a general framework, based on the single-pa…
One-dimensional conduction channels in the correlated Mott NiS2 arising from obstructed Wannier charges
Mikel Iraola, Haojie Guo, Fabio Orlandi +9
NiS2, a compound characterized by its pyrite structure, uniquely bridges the realms of strong correlation physics and topology. While bulk NiS2 is known to be a Mott or charge-tran…
Tunable superconductivity coexisting with the anomalous Hall effect in 1T'-WS2
Md Shafayat Hossain, Qi Zhang, David Graf +25
Transition metal dichalcogenides are a family of quasi-two-dimensional materials that display a high technological potential due to their wide range of electronic ground states, e.…
Topology of SmB6 revisited by means of topological quantum chemistry
Mikel Iraola, Iñigo Robredo, TItus Neupert +3
The mixed-valence compound SmB6 with partially filled samarium 4f flat bands hybridizing with 5d conduction bands is a paramount example of a correlated topological heavy-fermion s…
Influence of magnetism, strain and pressure on the band topology of EuCdAs
Adrian Valadkhani, Mikel Iraola, Axel Fünfhaus +4
Motivated by the wealth of proposals and realizations of nontrivial topological phases in EuCdAs, such as a Weyl semimetallic state and the recently discussed semimetallic…
Spectroscopic evidence for topological band structure in FeTeSe
Y. -F. Li, S. -D. Chen, M. Garcia-Diez +12
FeTeSe(FTS) occupies a special spot in modern condensed matter physics at the intersections of electron correlation, topology, and unconventional superconductivit…
Interacting topological quantum chemistry of Mott atomic limits
Martina O. Soldini, Nikita Astrakhantsev, Mikel Iraola +6
Topological quantum chemistry (TQC) is a successful framework for identifying (noninteracting) topological materials. Based on the symmetry eigenvalues of Bloch eigenstates at maxi…
Lecture Notes on Berry Phases and Topology
Barry Bradlyn, Mikel Iraola
In these notes, we review the role of Berry phases and topology in noninteracting electron systems. Topics including the adiabatic theorem, parallel transport, and Wannier function…
Elementary band representations for the single-particle Green's function of interacting topological insulators
Dominik Lessnich, Stephen M. Winter, Mikel Iraola +2
We discuss the applicability of elementary band representations (EBRs) to diagnose spatial- and time-reversal-symmetry protected topological phases in interacting insulators in ter…
Prediction of Double-Weyl Points in the Iron-Based Superconductor CaKFeAs
N. Heinsdorf, M. H. Christensen, M. Iraola +6
Employing a combination of symmetry analysis, low-energy modeling, and ab initio simulations, we predict the presence of magnetic-field-induced Weyl points close to the Fermi level…
Towards a Topological Quantum Chemistry description of correlated systems: the case of the Hubbard diamond chain
Mikel Iraola, Niclas Heinsdorf, Apoorv Tiwari +9
The recently introduced topological quantum chemistry (TQC) framework has provided a description of universal topological properties of all possible band insulators in all space gr…
IrRep: symmetry eigenvalues and irreducible representations of ab initio band structures
Mikel Iraola, Juan L. Mañes, Barry Bradlyn +3
We present IrRep - a Python code that calculates the symmetry eigenvalues of electronic Bloch states in crystalline solids and the irreducible representations under which they tran…
Novel Family of Topological Semimetals with Butterfly-like Nodal Lines
Xiaoting Zhou, Chuang-Han Hsu, Hugo Aramberri +6
In recent years, the exotic properties of topological semimetals (TSMs) have attracted great attention and significant efforts have been made in seeking for new topological phases…
Glide Symmetry Protected Higher-Order Topological Insulators from Semimetals with butterfly-like Nodal Lines
Xiaoting Zhou, Chuang-Han Hsu, Cheng-Yi Huang +5
Most topological insulators discovered today in spinful systems can be transformed from topological semimetals (TSMs) with vanishing bulk gap via introducing the spin-orbit couplin…
Fractional corner charges in spin-orbit coupled crystals
Frank Schindler, Marta Brzezińska, Wladimir A. Benalcazar +5
We study two-dimensional spinful insulating phases of matter that are protected by time-reversal and crystalline symmetries. To characterize these phases we employ the concept of c…
Doping of Graphene Nanoribbons via Functional Group Edge Modification
Eduard Carbonell-Sanromà, Jeremy Hieulle, Manuel Vilas-Varela +9
We report on the on-surface synthesis of 7 armchair graphene nanoribbons (7-AGNRs) substituted with nitrile (CN) functional groups. The CN groups are attached to the GNR backbone b…
