Twisted superfluid and supersolid phases of triplons in bilayer honeycomb magnets
Dhiman Bhowmick, Abhinava Chatterjee, Prasanta K. Panigrahi +1
We demonstrate that low-lying triplon excitations in a bilayer Heisenberg antiferromagnet provide a promising avenue to realize magnetic analogs of twisted superfluid and supersoli…
Weyl-triplons in SrCu2(BO3)2
Dhiman Bhowmick, Pinaki Sengupta
We propose that Weyl triplons are expected to appear in the low energy magnetic excitations in the canonical Shastry-Sutherland compound, \ce{SrCu2(BO3)2}, a quasi-2D quantum magne…
U(1)-Symmetry protected Dirac nodal loops of triplons in SrCu2(BO3)2
Dhiman Bhowmick, Pinaki Sengupta
We demonstrate the appearance of symmetry protected triplon Dirac modal lines in the low energy excitation spectrum of a realistic microscopic model of the geometrically frustrated…
The topological magnon bands in the Flux state in Sashtry-Sutherland lattice
Dhiman Bhowmick, Pinaki Sengupta
We investigate low energy magnon excitations above the non-collinear flux state and non-coplanar canted flux state in a Heisenberg anti-ferromagnet with Dzyaloshinskii-Moriya inter…
