Is the Majorana bound state a gravitationally neutral system?
Miguel A. Martin-Delgado
An argument is provided that confronts the strong equivalence principle (SEP) of general relativity with the superposition principle (SP) of quantum mechanics. The result has impli…
Twisted Fracton Models in Three Dimensions
Hao Song, Abhinav Prem, Sheng-Jie Huang +1
We study novel three-dimensional gapped quantum phases of matter which support quasiparticles with restricted mobility, including immobile "fracton" excitations. So far, most exist…
A bilayer Double Semion Model with Symmetry-Enriched Topological Order
L. Ortiz, M. A. Martin-Delgado
We construct a new model of two-dimensional quantum spin systems that combines intrinsic topo- logical orders and a global symmetry called flavour symmetry. It is referred as the b…
Topological Massive Dirac Edge Modes and Long-Range Superconducting Hamiltonians
O. Viyuela, D. Vodola, G. Pupillo +1
We discover novel topological effects in the one-dimensional Kitaev chain modified by long-range Hamiltonian deformations in the hopping and pairing terms. This class of models dis…
Symmetry-protected Topological Phases at Finite Temperature
O. Viyuela, A. Rivas, M. A. Martin-Delgado
We have applied the recently developed theory of topological Uhlmann numbers to a representative model of a topological insulator in two dimensions, the Qi-Wu-Zhang model. We have…
Two-Dimensional Density-Matrix Topological Fermionic Phases: Topological Uhlmann Numbers
O. Viyuela, A. Rivas, M. A. Martin-Delgado
We construct a topological invariant that classifies density matrices of symmetry-protected topological orders in two-dimensional fermionic systems. As it is constructed out of the…
