Two-dimensional - 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 - classical -state clock model with even 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 -state clock Hamiltonian using large-scale Monte Carlo simulations. Making contact with earlier…
Critical Behavior and Collective Modes at the Superfluid Transition in Amorphous Systems
Vishnu Pulloor Kuttanikkad, Martin Puschmann, Rajesh Narayanan +1
We investigate the critical behavior and the dynamics of the amplitude (Higgs) mode close to the superfluid-insulator quantum phase transition in an amorphous system (i.e., a syste…
