Time-dependent Hamiltonian Simulation via Magnus Expansion: Algorithm and Superconvergence

Di Fang, Diyi Liu, Rahul Sarkar

Hamiltonian simulation becomes more challenging as the underlying unitary becomes more oscillatory. In such cases, an algorithm with commutator scaling and a weak dependence, such…

Uniform $C^{k}$ Approximation of $G$ -Invariant and Antisymmetric Functions, Embedding Dimensions, and Polynomial Representations

Soumya Ganguly, Khoa Tran, Rahul Sarkar

For any subgroup $G$ of the symmetric group $S_{n}$ on $n$ symbols, we present results for the uniform $C^{k}$ approximation of $G$ -invariant functions by $G$ -invar…
