Schwinger model at finite temperature and density with beta VQE
We investigate a quantum gauge theory at finite temperature and density using a variational algorithm for near-term quantum devices. We adapt β -VQE to evaluate thermal and quantum expectation values

Exponential reduction of the sign problem at finite density in the 2+1D XY model via contour deformations
We study the 2+1 dimensional XY model at nonzero chemical potential μ on deformed integration manifolds, with the aim of alleviating its sign problem. We investigate several proposals for the

Solution of the Thirring model in thimble regularization
Thimble regularisation of lattice field theories has been proposed as a solution to the infamous sign problem. It is conceptually very clean and powerful, but it is in practice limited by a
Backpropagating Hybrid Monte Carlo algorithm for fast Lefschetz thimble calculations
This paper proposes a fast Hybrid Monte Carlo algorithm for evaluating the integral, where the force of the fictitious Hamilton dynamics on the deformed contour is backpropagate to that on the original contour, thereby reducing the required computational cost by a factor of the system size.
