Critical SO(5) scaling of entanglement entropy at honeycomb lattice deconfined criticality

Sankalp Kumar, Jonathan D'Emidio, Sumiran Pujari

The deconfined quantum critical point (DQCP) in square lattice S=1/2 quantum antiferromagnets has been extensively studied with a large body of evidence pointing to a weakly first-…

Pseudocriticality in antiferromagnetic spin chains

Sankalp Kumar, Sumiran Pujari, Jonathan D'Emidio

Weak first-order pseudocriticality with approximate scale invariance has been observed in a variety of settings, including the intriguing case of deconfined criticality in 2+1 dime…

Tomonaga-Luttinger liquid and quantum criticality in spin-1/2 antiferromagnetic Heisenberg chain C14H18CuN4O10 via Wilson ratio

Sharath Kumar Channarayappa, Sankalp Kumar, N. S. Vidhyadhiraja +9

The ground state of a one-dimensional spin-1/2 uniform antiferromagnetic Heisenberg chain (AfHc) is a Tomonaga-Luttinger liquid which is quantum-critical with respect to applied ma…
