Exact projected entangled pair ground states with topological Euler invariant
Thorsten B. Wahl, Wojciech J. Jankowski, Adrien Bouhon +2
We report on a class of gapped projected entangled pair states (PEPS) with non-trivial Euler topology motivated by recent progress in band geometry. In the non-interacting limit, t…
Superconductivity from domain wall fluctuations in sliding ferroelectrics
Gaurav Chaudhary, Ivar Martin
Bilayers of two-dimensional van der Waals materials that lack an inversion centre can show a novel form of ferroelectricity, where certain stacking arrangements of the two layers l…
Polarization textures in crystal supercells with topological bands
Wojciech J. Jankowski, Daniel Bennett, Aneesh Agarwal +2
Two-dimensional materials are a highly tunable platform for studying the momentum space topology of the electronic wavefunctions and real space topology in terms of skyrmions, mero…
On dualities of paired quantum Hall bilayer states at
Luca Rüegg, Gaurav Chaudhary, Robert-Jan Slager
Density-balanced, widely separated quantum Hall bilayers at can be described as two copies of composite Fermi liquids (CFLs). The two CFLs have interlayer weak-coupling B…
Theory of polarization textures in crystal supercells
Daniel Bennett, Wojciech J. Jankowski, Gaurav Chaudhary +2
Recently, topologically nontrivial polarization textures have been predicted and observed in nanoscale systems. While these polarization textures are interesting and promising in t…
Pairing of Composite-Electrons and Composite-Holes in Quantum Hall Bilayers
Luca Rüegg, Gaurav Chaudhary, Robert-Jan Slager
Motivated by recent experimental indications of preformed electron-hole pairs in quantum Hall bilayers at relatively large separation, we formulate a Chern-Simons (CS) theo…
Polar meron-antimeron networks in strained and twisted bilayers
Daniel Bennett, Gaurav Chaudhary, Robert-Jan Slager +2
Out-of-plane polar domain structures have recently been discovered in strained and twisted bilayers of inversion symmetry broken systems such as hexagonal boron nitride. Here we sh…
Quantum Geometric Contributions to the BKT Transition: Beyond Mean Field Theory
Zhiqiang Wang, Gaurav Chaudhary, Qijin Chen +1
We study quantum geometric contributions to the Berezinskii-Kosterlitz-Thouless (BKT) transition temperature, , in the presence of fluctuations beyond BCS theory.…
Vortex Lattice Structure and Topological Superconductivity in the Quantum Hall Regime
Gaurav Chaudhary, Allan H. MacDonald
Chiral topological superconductors are expected to appear as intermediate states when a quantum anomalous Hall system is proximity coupled to an s-wave superconductor and the magne…
Tunneling density of states, correlation energy, and spin polarization in the fractional quantum Hall regime
Gaurav Chaudhary, Dmitry K. Efimkin, Allan H. MacDonald
We derive exact sum-rules that relate the tunneling density of states (TDOS) of spinful electrons in the fractional quantum Hall (FQH) regime to the spin-dependent many body ground…
