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…

Helicity modulus and chiral symmetry breaking for boundary conditions with finite twist
Gaurav Khairnar, Thomas Vojta
We study the response of a two-dimensional classical XY model to a finite (non-infinitesimal) twist of the boundary conditions. We use Monte Carlo simulations to evaluate the free…
