Sparsity-dependent Complexity Lower Bound of Quantum Linear System Solvers
Hitomi Mori, Yuta Kikuchi, Marcello Benedetti +1
Quantum linear system (QLS) solvers are a fundamental class of quantum algorithms used in many potential quantum computing applications, including machine learning and solving diff…

BKT phase transition in a 2d system with long range dipole-dipole interaction
P. O. Fedichev, L. I. Men'shikov
We consider phase transitions in 2d XY-like systems with long range dipole-dipole interactions and demonstrate that BKT-type phase transition always occurs separating the ordered (…

Ferro-electric phase transition in a polar liquid and the nature of λ-transition in supercooled water
P. O. Fedichev, L. I. Menshikov
We develop a series of approximations to calculate free energy of a polar liquid. We show that long range nature of dipole interactions between the molecules leads to para-electric…
