Inequalities, identities, and bounds for divided differences of the exponential function
Qiulin Zeng, Nicholas Ezzell, Arman Babakhani +2
Let denote the divided difference of the exponential function. (i) We prove that exponential divided differences are log-submodular. (ii) We establish the…
A quantum Monte Carlo algorithm for arbitrary high-spin Hamiltonians
Arman Babakhani, Lev Barash, Itay Hen
We present a universal quantum Monte Carlo algorithm for simulating arbitrary high-spin (spin greater than 1/2) Hamiltonians, based on the recently developed permutation matrix rep…
SNS Junctions along the BCS-BEC Crossover
Gautam Rai, Arman Babakhani, Ying Wang +2
We present a theory of SNS junctions, a normal metal sandwiched between two superconductors, along the crossover from the BCS to the BEC regime. We calculate the Josephson current…
A quantum Monte Carlo algorithm for arbitrary spin-1/2 Hamiltonians
Lev Barash, Arman Babakhani, Itay Hen
We present a universal parameter-free quantum Monte Carlo (QMC) algorithm designed to simulate arbitrary spin- Hamiltonians. To ensure the convergence of the Markov chain to e…
G-crossed Modularity of Symmetry-Enriched Topological Phases
Arman Babakhani, Parsa Bonderson
The universal properties of (2 + 1)D topological phases of matter enriched by a symmetry group G are described by G-crossed extensions of unitary modular tensor categories (UMTCs).…
Non-Abelian eigenstate thermalization hypothesis
Chaitanya Murthy, Arman Babakhani, Fernando Iniguez +2
The eigenstate thermalization hypothesis (ETH) explains why chaotic quantum many-body systems thermalize internally if the Hamiltonian lacks symmetries. If the Hamiltonian conserve…
Continuous quantum error correction for evolution under time-dependent Hamiltonians
J. Atalaya, S. Zhang, M. Y. Niu +4
We develop a protocol for continuous operation of a quantum error correcting code for protection of coherent evolution due to an encoded Hamiltonian against environmental errors, u…
