Static and Dynamical Characterization of Ground State Phases Induced by Frustration and Magnetic Field in the Spin-1 Orthogonal Dimer Chain
Ernest Ong, Dhiman Bhowmick, Sharoz Schezwen +1
The spin- orthogonal dimer chain is investigated using the Density Matrix Renormalization Group (DMRG) algorithm. A transformation to a basis that uses the local eigenstates of…
Quantum Skyrmion Liquid
Dhiman Bhowmick, Andreas Haller, Deepak S. Kathyat +2
Skyrmions are topological magnetic textures, mostly treated classically, studied extensively due to their potential spintronics applications due to their topological stability. How…
Tuning bulk topological magnon properties with light-induced magnons
Dhiman Bhowmick, Hao Sun, Bo Yang +1
Although theoretical modelling and inelastic neutron scattering measurements have indicated the presence of topological magnon bands in multiple quantum magnets, experiments remain…
Discrete time crystal made of topological edge magnons
Dhiman Bhowmick, Hao Sun, Bo Yang +1
We report the emergence of time-crystalline behavior in the π-Berry phase protected edge states of a Heisenberg ferromagnet in the presence of an external driving field. The magnon…
Topological excitations in quasi two-dimensional quantum magnets with weak interlayer interactions
Dhiman Bhowmick
The study of topological magnetic excitations has attracted widespread attention in the past few years. In this thesis, I have studied some examples of novel topological magnonic p…
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…
