Exponential improvements in the simulation of lattice gauge theories using near-optimal techniques
Mason L. Rhodes, Michael Kreshchuk, Shivesh Pathak
We report a first-of-its-kind analysis on post-Trotter simulation of U(1), SU(2) and SU(3) lattice gauge theories including fermions in arbitrary spatial dimension. We provide expl…
Non-Orientable AdS and its Holography
Shivesh Pathak, Lucas Kocia Kovalsky
Known solutions to three-dimensional gravity with negative cosmological constant so far consist of either AdS or its orbifolds (or orientifolds). We geometrically derive a nove…
Requirements for building effective Hamiltonians using quantum-enhanced density matrix downfolding
Shivesh Pathak, Antonio E. Russo, Stefan Seritan +4
Density matrix downfolding (DMD) is a technique for regressing low-energy effective Hamiltonians from quantum many-body Hamiltonians. One limiting factor in the accuracy of classic…
