Weak-strong uniqueness of the full coupled Navier-Stokes and Q-tensor system in dimension three
Fan Yang, Junjie Zhou
In this paper, we study the weak-strong uniqueness for the Leray-Hopf type weak solutions to the Beris-Edwards model of nematic liquid crystals in with an arbitrary paramete…
Symmetries of Spin-Splitting Induced by Spin-Orbit Coupling in Non-magnetic Crystals
Fan Yang, Rafael M. Fernandes, Turan Birol
Spin-orbit coupling (SOC) leads to splitting of otherwise spin-degenerate bands in noncentrosymmetric materials, even if time-reversal symmetry is present. While this gives rise to…
Dissipation-driven topological phase transitions in open quantum systems independent of system Hamiltonian
Tian-Shu Deng, Fan Yang
We investigate dissipation-driven topological phase transitions in one-dimensional quantum open systems governed by the Lindblad equation with linear dissipation operators, which e…
Arithmetic spectral transition for the unitary almost Mathieu operator
Fan Yang
We study the unitary almost Mathieu operator (UAMO), a one-dimensional quasi-periodic unitary operator arising from a two-dimensional discrete-time quantum walk on in…
Topological Signatures of Magnetic Phase Transitions with Majorana Fermions through Local Observables and Quantum Information
Karyn Le Hur, Fan Yang, Magali Korolev
The one-dimensional (1D) quantum spin model can be viewed as a strong-coupling analogue of the Schrieffer-Su-Heeger model with two inequivalent alternating Ising coupling…
Non-equilibrium Dynamics of Fermi Polarons Driven by Time-dependent Interaction
Fan Yang, Ran Qi
We systematically studied the dynamics of Fermi polarons driven by time-dependent scattering length using a time-dependent variational method. Starting from the non-interacting ini…
