In this work, we address the ground-state properties of the anisotropic spin-1/2 Heisenberg
XYZ chain under the interplay of magnetic fields and the Dzyaloshinskii-Moriya (DM) …

We study Majorana chain with the shortest possible interaction term and in the presence of
hop** alternation. When formulated in terms of spins the model corresponds to the …

Motivated by the experimental observation of a quantized 5/2 thermal conductance at filling
ν= 5/2, a result incompatible with both the Pfaffian and the anti-Pfaffian states, we have …

We study the emergence of exact Majorana zero modes (EMZMs) in a one-dimensional
quantum transverse compass model with both the nearest-neighbor interactions and …

We propose and investigate a simple one-dimensional model for a single-channel quantum
wire hosting electrons that interact repulsively and are subject to a significant spin-orbit …

Symmetry is fundamental in the description and simulation of quantum systems. Leveraging
symmetries in classical simulations of many-body quantum systems often results in an …

In this work, we study the topological phase transitions of a Kitaev chain generalized by the
addition of nearest-neighbor Coulomb interaction. We show the presence of a robust …

We show that mutual statistics between quantum particles can be tuned to generate
emergent novel few-particle quantum mechanics for the boundary modes of symmetry …

Motivated by the recent observation that exponentially long coherence times can be
achieved for edge spins in models with strong zero modes, we study the impact of level …

We show that the effective coupling between the spin-1/2 edge states of a spin-1 chain of
finite length can be continuously tuned by frustration. For the J 1− J 2 model with nearest …
