Punctured-Chern topological invariants for semi-metallic bandstructures
Ankur Das, Eyal Cornfeld, Sumiran Pujari
Topological insulator-based methods underpin the topological classification of gapped bands, including those surrounding semi-metallic nodal defects. However, multiple bands with g…
Tenfold Topology of Crystals: Unified classification of crystalline topological insulators and superconductors
Eyal Cornfeld, Shachar Carmeli
The celebrated tenfold-way of Altland-Zirnbauer symmetry classes discern any quantum system by its pattern of non-spatial symmetries. It lays at the core of the periodic table of t…
Spin-polarized superconductivity: order parameter topology, current dissipation, and multiple-period Josephson effect
Eyal Cornfeld, Mark S. Rudner, Erez Berg
We discuss transport properties of fully spin-polarized triplet superconductors, where only electrons of one spin component (along a certain axis) are paired. Due to the structure…
Signatures of Topological Superconductivity and Parafermion Zero Modes in Fractional Quantum Hall Edges
Noam Schiller, Eyal Cornfeld, Erez Berg +1
Parafermion zero modes are exotic emergent excitations that can be considered as generalizations of Majorana fermions. Present in fractional quantum Hall-superconduc…
Classification of Crystalline Topological Insulators and Superconductors with Point Group Symmetries
Eyal Cornfeld, Adam Chapman
Crystalline topological phases have recently attracted a lot of experimental and theoretical attention. Key advances include the complete elementary band representation analyses of…
Entanglement spectroscopy of non-Abelian anyons: Reading off quantum dimensions of individual anyons
Eyal Cornfeld, L. Aviad Landau, Kirill Shtengel +1
We study the entanglement spectrum of topological systems hosting non-Abelian anyons. Akin to energy levels of a Hamiltonian, the entanglement spectrum is composed of symmetry mult…
BACH: Grand Challenge on Breast Cancer Histology Images
Guilherme Aresta, Teresa Araújo, Scotty Kwok +33
Breast cancer is the most common invasive cancer in women, affecting more than 10% of women worldwide. Microscopic analysis of a biopsy remains one of the most important methods to…
Imbalance Entanglement: Symmetry Decomposition of Negativity
Eyal Cornfeld, Moshe Goldstein, Eran Sela
In the presence of symmetry, entanglement measures of quantum many-body states can be decomposed into contributions arising from distinct symmetry sectors. Here we investigate the…
Charge Fractionalization in a Kondo Device
L. A. Landau, E. Cornfeld, E. Sela
We study nonequilibrium transport through a charge Kondo device realizing the two-channel Kondo critical point in a recent experiment by Iftikhar et al. By computing the current an…
Entanglement entropy and boundary renormalization group flow - exact results in the Ising universality class
Eyal Cornfeld, Eran Sela
The entanglement entropy in one dimensional critical systems with boundaries has been associated with the noninteger ground state degeneracy. This quantity, being a characteristic…
Laughlin-like states in bosonic and fermionic atomic synthetic ladders
Marcello Calvanese Strinati, Eyal Cornfeld, Davide Rossini +5
The combination of interactions and static gauge fields plays a pivotal role in our understanding of strongly-correlated quantum matter. Cold atomic gases endowed with a synthetic…
Chiral currents in one-dimensional fractional quantum Hall states
Eyal Cornfeld, Eran Sela
We study bosonic and fermionic quantum two-leg ladders with orbital magnetic flux. In such systems, the ratio, , of particle density to magnetic flux shapes the phase-space, as…
Shot-Noise in Fractional Wires: a Universal Fano-Factor Different than the Tunneling Charge
Eyal Cornfeld, Izhar Neder, Eran Sela
We consider partially gapped one dimensional (1D) conductors connected to normal leads, as realized in fractional helical wires. At certain electron densities, some distinct charge…
