Two-dimensional $J_{1}$ - $J_{2}$ clock model: Enhanced symmetries, emergent orders, and Landau-incompatible transitions

Vishnu Pulloor Kuttanikkad, Abhishodh Prakash, Rajesh Narayanan +1

We present a comprehensive study on the frustrated $J_{1}$ - $J_{2}$ classical $q$ -state clock model with even $q > 4$ on a two-dimensional square lattice, revealing a rich ensemble of pha…

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…

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 $q$ -state clock Hamiltonian using large-scale Monte Carlo simulations. Making contact with earlier…
