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…
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…
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…
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…
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…
Nematic order in topological SYK models
Andrew Hardy, Anjishnu Bose, Arun Paramekanti
We study a class of multi-orbital models based on those proposed by Venderbos, Hu, and Kane which exhibit an interplay of topology, interactions, and fermion incoherence. In the no…
Proximate Dirac spin liquid in honeycomb lattice - XXZ model: Numerical study and application to cobaltates
Anjishnu Bose, Manodip Routh, Sreekar Voleti +4
Recent theoretical and experimental work suggest that the honeycomb cobaltates, initially proposed as candidate Kitaev quantum magnets, are in fact described by a pseudospin-…
Chiral Broken Symmetry Descendants of the Kagomé Lattice Chiral Spin Liquid
Anjishnu Bose, Arijit Haldar, Erik S. Sørensen +1
The breaking of chiral and time-reversal symmetries provides a pathway to exotic quantum phenomena and topological phases. In particular, the breaking of chiral (mirror) symmetry i…
Selection rules for the S-Matrix bootstrap
Anjishnu Bose, Aninda Sinha, Shaswat S Tiwari
We examine the space of allowed S-matrices on the Adler zeros' plane using the recently resurrected (numerical) S-matrix bootstrap program for pion scattering. Two physical quantit…
Relative entropy in scattering and the S-matrix bootstrap
Anjishnu Bose, Parthiv Haldar, Aninda Sinha +2
We consider entanglement measures in 2-2 scattering in quantum field theories, focusing on relative entropy which distinguishes two different density matrices. Relative entropy is…
