Variationally Optimized Imaginary-time Polynomial Filters for Ground State Projection

In this work, we develop a variational imaginary-time evolution (ITE) framework based on polynomial filtering, derived from an operator-level action principle, which yields an optimized non-unitary projector expressed as a polynomial in the Hamiltonian. Starting from a single-ancilla, first-order imaginary-time update...

Thermodynamics and Kinetics of Dimerization-Coupled Fold Switching in the Chemokine XCL1.

Metamorphic proteins challenge the classical view of protein folding by reversibly interconverting between two distinct, stable native structures. XCL1 (lymphotactin) is a prototypical example, transitioning between a monomeric mixed- α / β chemokine fold and an alternate all- β fold that forms a stable dimer. Here we...
