Anatomy of Z2 fluxes in anyon Fermi liquids and Bose condensates
Oscar Pozo, Peng Rao, Chuan Chen +1
We study in detail the properties of pi-fluxes embedded in a state with a finite density of anyons that form either a Fermi liquid or a Bose-Einstein condensate. By employing a rec…
Computing observables without eigenstates: applications to Bloch Hamiltonians
Oscar Pozo, Fernando de Juan
Calculating the observables of a Hamiltonian requires taking matrix elements of operators in the eigenstate basis. Since eigenstates are only defined up to arbitrary phases that de…
Giant topological longitudinal circular photo-galvanic effect in the chiral multifold semimetal CoSi
Zhuoliang Ni, K. Wang, Y. Zhang +10
The absence of mirror symmetry, or chirality, is behind striking natural phenomena found in systems as diverse as DNA and crystalline solids. A remarkable example occurs when chira…
Quantization in chiral higher order topological insulators: circular dichroism and local Chern marker
Oscar Pozo, Cécile Repellin, Adolfo G. Grushin
The robust quantization of observables in units of universal constants is a hallmark of topological phases. We show that chiral higher order topological insulators (HOTIs), bulk in…
Anisotropic fixed points in Dirac and Weyl semimetals
Oscar Pozo, Yago Ferreiros, María A. H. Vozmediano
The effective low energy description of interacting Dirac and Weyl semimetals is that of massless quantum electrodynamics with several Lorentz breaking material parameters. We perf…
