Hidden Angular Momentum Loop Currents in Symmetric Crystals
Rule Yi, Vincent P. Flynn, Benedetta Flebus
Loop-current order has been invoked to explain unconventional electronic phases, with the crystal lattice usually regarded as a passive host for the underlying collective dynamics.…
Superfluid Spin Transport in the Van der Waals Antiferromagnet CrCl
Peisen Yuan, Xiaomin Guo, Vincent Flynn +3
Over the past decade, the quest for spin superfluidity has moved to the forefront of spintronics, driven by the promise of phase-gradient-driven, ultra-low-loss spin transport. How…
Hidden Frustration in Collinear Altermagnets: Pairing Vortices and Equilibrium Spin Current Loops
Vincent P. Flynn, Benedetta Flebus
We show that a magnet can remain perfectly collinear while its quantum vacuum circulates. In a centrosymmetric altermagnet, a symmetry-allowed locally staggered Dzyaloshinskii-Mori…
Quantum criticality beyond thermodynamic stability
Mariam Ughrelidze, Vincent P. Flynn, Emilio Cobanera +1
For a many-body system in equilibrium, described by a thermodynamically stable Hamiltonian, quantum criticality is associated with structural changes of the many-body ground state.…
Dynamical metastability and transient topological magnons in interacting driven-dissipative magnetic systems
Vincent P. Flynn, Lorenza Viola, Benedetta Flebus
Metastability, i.e., partial relaxation to long-lived, quasi-stationary states before true asymptotic equilibrium sets in, emerges ubiquitously in classical and quantum dynamical s…
Emergent spatiotemporal order and nonreciprocity in driven-dissipative nonlinear magnetic systems
Vincent Flynn, Benedetta Flebus
The identification of platforms with independently tunable nonlinearity and non-Hermiticity promises a quantitative route to far-from-equilibrium universality across many-body syst…
