Topological Transverse Transport without a Gap in Critical Topological Flat Bands
Chang-geun Oh, Tomoki Ozawa, Jun-Won Rhim
Quantized Hall transport is traditionally anchored to a bulk spectral gap, which isolates the occupied subspace and exponentially suppresses thermal deviations. Recently discovered…
Non-Abelian Gauge Field Mechanics
Ivan Velkovsky, Carlos Camacho, Tomoki Ozawa +2
Non-Abelian gauge fields play a key role in describing the behavior of particles whose motion is coupled to internal degrees of freedom, such as their spin. Here, we experimentally…
Hall viscosity from metric-sensitive dichroic probes
Alberto Nardin, Bruno Mera, Anaïs Defossez +3
Hall viscosity characterizes the geometric response of a quantum Hall droplet to deformations of the underlying metric, yet it has remained difficult to measure directly. We propos…
Non-Hermitian Landau Levels
Anton Montag, Tomoki Ozawa
We formulate non-Hermitian Landau levels in two-dimensional systems under a complex perpendicular magnetic field. In the symmetric gauge, we derive their discretely spaced, highly…
Emergent topological properties in spatially modulated sub-wavelength barrier lattices
Giedrius Žlabys, Wen-Bin He, Domantas Burba +3
We investigate topological phenomena in a spatially modulated Dirac- lattice, where the scattering potential varies periodically in space. Changing the potential modulation freq…
Harmonic band theory: rigidity of non-zero degree harmonic maps from 2-torus to complex projective space
Yoshinori Hashimoto, Bruno Mera, Tomoki Ozawa
We prove the rigidity of isotropic harmonic maps from a 2-torus to a complex projective space, when they are constructed from holomorphic embeddings associated to complete linear s…
