Meron-Cluster Simulation of Quantum Spin Ladders in a Magnetic Field
S. Chandrasekharan, B. Scarlet, U. -J. Wiese
Numerical simulations of numerous quantum systems suffer from the notorious sign problem. Meron-cluster algorithms lead to an efficient solution of sign problems for both fermionic…
Fermion Cluster Algorithms
Shailesh Chandrasekharan
Cluster algorithms have been recently used to eliminate sign problems that plague Monte-Carlo methods in a variety of systems. In particular such algorithms can also be used to sol…
Meron-Cluster Simulation of a Chiral Phase Transition with Staggered Fermions
S. Chandrasekharan, J. Cox, K. Holland +1
We examine a (3+1)-dimensional model of staggered lattice fermions with a four-fermion interaction and Z(2) chiral symmetry using the Hamiltonian formulation. This model cannot be…
Non-perturbative Renormalization Constants using Ward Identities
Tanmoy Bhattacharya, Shailesh Chandrasekharan, Rajan Gupta +2
We extend the application of axial Ward identities to calculate and , coefficients that give the mass dependence of the renormalization constants of the correspondi…
Meron-Cluster Solution of Fermion Sign Problems
Shailesh Chandrasekharan, Uwe-Jens Wiese
We present a general strategy to solve the notorious fermion sign problem using cluster algorithms. The method applies to various systems in the Hubbard model family as well as to…
