Phase transitions in the frustrated Ising model on the square lattice
Songbo Jin, Arnab Sen, Wenan Guo +1
We consider the thermal phase transition from a paramagnetic to stripe-antiferromagnetic phase in the frustrated two-dimensional square-lattice Ising model with competing interacti…
Quasi-adiabatic quantum Monte Carlo algorithm for quantum evolution in imaginary time
Cheng-Wei Liu, Anatoli Polkovnikov, Anders W. Sandvik
We propose a quantum Monte Carlo (QMC) algorithm for non-equilibrium dynamics in a system with a parameter varying as a function of time. The method is based on successive applicat…
The performance of the quantum adiabatic algorithm on random instances of two optimization problems on regular hypergraphs
Edward Farhi, David Gosset, Itay Hen +4
In this paper we study the performance of the quantum adiabatic algorithm on random instances of two combinatorial optimization problems, 3-regular 3-XORSAT and 3-regular Max-Cut.…
Correlated valence-bond states
Yu-Cheng Lin, Ying Tang, Jie Lou +1
We study generalizations of the singlet-sector amplitude-product (AP) states in the valence-bond basis of S=1/2 quantum spin systems. In the standard AP states, the weight of a til…
Bridging lattice-scale physics and continuum field theory with quantum Monte Carlo simulations
Ribhu K. Kaul, Roger G. Melko, Anders W. Sandvik
We discuss designer Hamiltonians---lattice models tailored to be free from sign problems ("de-signed") when simulated with quantum Monte Carlo methods but which still host complex…
Antiferromagnetic order in systems with doublet ground states
Sambuddha Sanyal, Argha Banerjee, Kedar Damle +1
We use projector Quantum Monte-Carlo methods to study the doublet ground states of two dimensional antiferromagnets on a square lattice with…
