Local time-reversal-invariant topological markers in two dimensions
Thomas Klein Kvorning, Miguel F. Martínez, Julia D. Hannukainen
Local topological markers provide a real-space characterization of topological phases and are suited to noncrystalline models. We derive a local topological marker, the Chern-Simon…
Characterizing topology at nonzero temperature: Topological invariants and indicators in the extended SSH model
Julia D. Hannukainen, Nigel R. Cooper
We compare three complementary diagnostics for mixed Gaussian states at nonzero temperature, focusing on the Su-Schrieffer-Heeger (SSH) chain and its inversion-symmetric extension.…
One-Particle Density Matrix Framework for Mode-Shell Correspondence: Characterizing Topology in Amorphous Higher-Order Topological Insulators
Miguel F. Martínez, Lucien Jezequel, Jens H. Bardarson +2
We present a framework for characterizing higher-order topological phases directly from the one-particle density matrix, without any reference to an underlying Hamiltonian. Our app…
Interacting Local Topological Markers: A one-particle density matrix approach for characterizing the topology of interacting and disordered states
Julia D. Hannukainen, Miguel F. Martínez, Jens H. Bardarson +1
While topology is a property of a quantum state itself, most existing methods for characterizing the topology of interacting phases of matter require direct knowledge of the underl…
Amorphous topological matter: theory and experiment
Paul Corbae, Julia D. Hannukainen, Quentin Marsal +2
Topological phases of matter are ubiquitous in crystals, but less is known about their existence in amorphous systems, that lack long-range order. In this perspective, we review th…
Local Topological Markers in Odd Spatial Dimensions and Their Application to Amorphous Topological Matter
Julia D. Hannukainen, Miguel F. Martinez, Jens H. Bardarson +1
Local topological markers, topological invariants evaluated by local expectation values, are valuable for characterizing topological phases in materials lacking translation invaria…
Non-Hermitian chiral anomalies
Sharareh Sayyad, Julia D. Hannukainen, Adolfo G. Grushin
The chiral anomaly underlies a broad number of phenomena, from enhanced electronic transport in topological metals to anomalous currents in the quark-gluon plasma. The discovery of…
Electric manipulation of domain walls in magnetic Weyl semimetals via the axial anomaly
Julia D. Hannukainen, Alberto Cortijo, Jens H. Bardarson +1
We show how the axial (chiral) anomaly induces a spin torque on the magnetization in magnetic Weyl semimetals. The anomaly produces an imbalance in left- and right-handed chirality…
Axial anomaly generation by domain wall motion in Weyl semimetals
Julia D. Hannukainen, Yago Ferreiros, Alberto Cortijo +1
A space-time dependent node separation in Weyl semimetals acts as an axial vector field. Coupled with domain wall motion in magnetic Weyl semimetals, this induces axial electric an…
Dissipation driven quantum phase transitions and symmetry breaking
Julia Hannukainen, Jonas Larson
By considering a solvable driven-dissipative quantum model, we demonstrate that continuous second order phase transitions in dissipative systems may occur without an accompanying s…
