Scaling in the Fan of an Unconventional Quantum Critical Point
Roger G. Melko, Ribhu K. Kaul
We present results of extensive finite-temperature Quantum Monte Carlo simulations on a SU(2) symmetric S=1/2 quantum antiferromagnet with a four-spin interaction [Sandvik, Phys. R…
Algebraic charge liquids
Ribhu K. Kaul, Yong Baek Kim, Subir Sachdev +1
High temperature superconductivity emerges in the cuprate compounds upon changing the electron density of an insulator in which the electron spins are antiferromagnetically ordered…
Hole dynamics in an antiferromagnet across a deconfined quantum critical point
Ribhu K. Kaul, Alexei Kolezhuk, Michael Levin +2
We study the effects of a small density of holes, delta, on a square lattice antiferromagnet undergoing a continuous transition from a Neel state to a valence bond solid at a decon…
