Polaronic mechanism of Nagaoka ferromagnetism in Hubbard models
Rhine Samajdar, R. N. Bhatt
The search for elusive Nagaoka-type ferromagnetism in the Hubbard model has recently enjoyed renewed attention with the advent of a variety of experimental platforms enabling its r…
Equilibrium dynamics of infinite-range quantum spin glasses in a field
Maria Tikhanovskaya, Subir Sachdev, Rhine Samajdar
We determine the low-energy spectrum and Parisi replica symmetry breaking function for the spin glass phase of the quantum Ising model with infinite-range random exchange interacti…
Quantum speedup for combinatorial optimization with flat energy landscapes
Madelyn Cain, Sambuddha Chattopadhyay, Jin-Guo Liu +3
Designing quantum algorithms with a speedup over their classical analogs is a central challenge in quantum information science. Motivated by recent experimental observations of a s…
Circumventing superexponential runtimes for hard instances of quantum adiabatic optimization
Benjamin F. Schiffer, Dominik S. Wild, Nishad Maskara +3
Classical optimization problems can be solved by adiabatically preparing the ground state of a quantum Hamiltonian that encodes the problem. The performance of this approach is det…
Dynamics of magnetization at infinite temperature in a Heisenberg spin chain
Eliott Rosenberg, Trond Andersen, Rhine Samajdar +178
Understanding universal aspects of quantum dynamics is an unresolved problem in statistical mechanics. In particular, the spin dynamics of the 1D Heisenberg model were conjectured…
Quantum turnstiles for robust measurement of full counting statistics
Rhine Samajdar, Ewan McCulloch, Vedika Khemani +2
We present a scalable protocol for measuring full counting statistics (FCS) in experiments or tensor-network simulations. In this method, an ancilla in the middle of the system act…
