Symmetry constrained field theories for chiral spin liquid to spin crystal transitions
Anjishnu Bose, Andrew Hardy, Naren Manjunath +2
We consider the spin rotationally invariant Kalmeyer-Laughlin chiral spin liquid (CSL) in systems with broken time-reversal symmetry and explore symmetry constraints on possible co…
Charge ordering and spontaneous topological Hall effect in bilayer skyrmion crystals
Andrew Hardy, Anjishnu Bose, Tanmay Grover +1
Magnetic skyrmion crystals with zero net skyrmion charge and zero topological Hall response are interesting candidate phases which can occur at a vanishing magnetic field in centro…
Modified large- approach to gapless spin liquids, magnetic orders, and dynamics: Application to triangular lattice antiferromagnets
Anjishnu Bose, Kathleen Hart, Ruairidh Sutcliffe +1
Recent work has shown that the triangular lattice spin- - Heisenberg and XXZ antiferromagnets may exhibit coplanar or supersolid orders proximate to a gapless Dirac…
Altermagnetism and superconductivity in a multiorbital t-J model
Anjishnu Bose, Samuel Vadnais, Arun Paramekanti
Motivated by exploring doped multi-orbital antiferromagnets (AFMs) and altermagnets (ALMs) we explore minimal - models on the square-octagon lattice which favor such collinea…
Spin dynamics of an easy-plane Dirac spin liquid in a frustrated XY model: Application to honeycomb cobaltates
Anjishnu Bose, Arun Paramekanti
Recent work has shown that the honeycomb lattice spin- - XY model, with nearest-neighbor ferromagnetic exchange and frustration induced by third-neighbor antif…
