Phases and Phase Transitions of the Disordered Quantum Clock Model
Vishnu Pulloor Kuttanikkad, Gaurav Khairnar, Rajesh Narayanan +1
We study the phases and phase transitions of a disordered one-dimensional quantum -state clock Hamiltonian using large-scale Monte Carlo simulations. Making contact with earlier…

Amplitude mode at the superfluid-insulator transition on a random lattice
Vishnu Pulloor Kuttanikkad, Rajesh Narayanan, Thomas Vojta
We study the superfluid-insulator quantum phase transition of interacting bosons by means of large-scale Monte Carlo simulations in the presence of both topological and generic que…
