Measures of Chirality in Mixed-State Topological Phases
Shijun Sun, Bader Aldossari, Rasmit Devkota +1
What does it mean for a mixed-state topological phase to be chiral? Mathematically, chirality can be sharply characterized through the symmetry algebra of the mixed state. Physical…
Holographic View of Mixed-State Symmetry-Protected Topological Phases in Open Quantum Systems
Shijun Sun, Jian-Hao Zhang, Zhen Bi +1
We establish a holographic duality between d-dimensional mixed-state symmetry-protected topological phases (mSPTs) and (d+1)-dimensional subsystem symmetry-protected topological st…
Quasispins of vacancy defects and their interactions in disordered antiferromagnets
Muhammad Sedik, Shijun Sun, Arthur P. Ramirez +1
Vacancy defects in disordered magnetic materials are known to act as effective spins, ``quasispins'', in response to an external magnetic field. In the dilute limit, the contributi…
Quasispins of vacancy defects in Ising chains with nearest- and next-to-nearest-neighbour interactions
Shijun Sun, Arthur P. Ramirez, Sergey Syzranov
Motivated by frustrated magnets and quasi-one-dimensional magnetic materials, we study the magnetic properties of 1D Ising chains with nearest-neighbour (NN) and weaker next-to-nea…
Interactions-disorder duality and critical phenomena in nodal semimetals, dilute gases and other systems
Shijun Sun, Sergey Syzranov
We investigate classes of interacting systems that allow for a mapping to disordered noninteracting systems. As we show, such a mapping is possible for interacting systems with a s…
