Emergence of a monopole phase in the Heisenberg model on the triangular lattice for small magnetic fields
Sasank Budaraju, Shi Feng, Josef Willsher +3
We investigate the ground-state phase diagram of the Heisenberg model on the triangular lattice under an external Zeeman field by using the variational Monte Carlo…
Triangular - Heisenberg Antiferromagnet in a Magnetic Field
Thomas Bader, Shi Feng, Sasank Budaraju +3
The behavior of the paradigmatic triangular lattice Heisenberg antiferromagnet in a magnetic field remains unsettled despite decades of study. We map out the phase diagra…
Monopole excitations in the Dirac spin liquid on the triangular lattice
Sasank Budaraju, Alberto Parola, Yasir Iqbal +2
The Dirac spin liquid might realize an exotic phase of matter whose low-energy properties are described by quantum electrodynamics in dimensions, where gapless modes e…
Simulating chiral spin liquids with fermionic Projected Entangled Paired States
Sasank Budaraju, Didier Poilblanc, Sen Niu
Chiral Spin Liquids (CSL) based on spin-1/2 fermionic Projected Entangled Pair States (fPEPS) are considered on the square lattice. First, fPEPS approximants of Gutzwiller-projecte…
Piercing the Dirac spin liquid: From a single monopole to chiral states
Sasank Budaraju, Yasir Iqbal, Federico Becca +1
The parton approach for quantum spin liquids gives a transparent description of low-energy elementary excitations, e.g., spinons and emergent gauge-field fluctuations. The latter o…
