v 1 2 2 M ay 1 99 6 Suppression of the negative sign problem in quantum Monte
نویسنده
چکیده
We present a new Monte Carlo algorithm for simulating quantum spin systems which is able to suppress the negative sign problem. This algorithm has only a linear complexity in the lattice size used for the simulation. A general description and a rigorous proof of its correctness is given. Its efficiency is tested on a simple 2-dimensional fermionic model. For this model we show that our algorithm eliminates the sign problem. [email protected] 1

M ay 1 99 6 A new approach to significantly reduce the negative sign problem in quantum Monte
We present a new approach for Monte Carlo simulations of quantum spin systems which is able to strongly reduce the negative sign problem. Its efficiency is tested on a simple 2-dimensional fermionic model for which we show that our algorithm eliminates the sign problem. The investigation of quantum spin systems is important for understanding the physics related to strongly correlated electrons ...

A quantum spin system can be modelled by an equivalent classical system, with an effective Hamiltonian obtained by integrating all non-zero frequency modes out of the path integral. The effective Hamiltonian H eff ({S i }) derived from the coherent-state integral is highly singular: the quasiprobability density exp(−βH eff), a Wigner function, imposes quantisation through derivatives of delta f...

We present a new approach for Monte Carlo simulations of lattice quantum spin systems which is able to eliminate the negative sign problem. Its complexity is linear in the volume of the lattice. Its efficiency is tested on a simple 2-dimensional fermionic model. The investigation of quantum spin systems is important for understanding the physics related to strongly correlated electrons and high...

In this article we analyze the vacuum structure of pure SU(2) Yang-Mills using non-perturbative techniques. Monte Carlo simulations are performed for the lattice gauge theory with external sources to obtain the effective potential. Evidence from the lattice gauge theory indicating the presence of the unstable mode in the effective potential is reported.

We derive simple formulas connecting the generalized Wigner functions for s-ordering with the density matrix, and vice-versa. These formulas proved very useful for quantum mechanical applications, as, for example, for connecting master equations with Fokker-Planck equations, or for evaluating the quantum state from Monte Carlo simulations of Fokker-Planck equations, and finally for studying pos...
