Topology from Decoherence
Alexandre Chaduteau, Derek Lee, Frank Schindler +1
Decoherence is conventionally regarded as an obstacle to realizing topological quantum phases. This has motivated extensive efforts to suppress noise in candidate topological mater…
Topological Dislocation Response in Elementary Semiconductors
Yuteng Zhou, Alexandre Chaduteau, Frank Schindler
We study elementary semiconductors and insulators that are symmetric under spatial inversion: silicon, diamond, germanium, and black phosphorene. These materials are ideal candidat…
Lindbladian versus Postselected Non-Hermitian Topology
Alexandre Chaduteau, Derek K. K. Lee, Frank Schindler
The recent topological classification of non-Hermitian `Hamiltonians' is usually interpreted in terms of pure quantum states that decay or grow with time. However, many-body system…
Momentum-space modulated symmetries in the Luttinger liquid
Alexandre Chaduteau, Nyan Raess, Henry Davenport +1
The chiral Luttinger liquid develops quantum chaos as soon as a -- however slight -- nonlinear dispersion is introduced for the microscopic electronic degrees of freedom. For this…
