Quantum discord in a spin system with symmetry breaking
Bruno Tomasello, Davide Rossini, Alioscia Hamma +1
We analyze the quantum discord Q throughout the low-temperature phase diagram of the quantum XY model in transverse field. We first focus on the T=0 order-disorder quantum phase tr…

Two liquid states of matter: A new dynamic line on a phase diagram
V. V. Brazhkin, Yu. D. Fomin, A. G. Lyapin +2
It is generally agreed that the supercritical region of a liquid consists of one single state (supercritical fluid). On the other hand, we show here that liquids in this region exi…

Liquid heat capacity in the approach from the solid state: anharmonic theory
Dima Bolmatov, Kostya Trachenko
Calculating liquid energy and heat capacity in general form is an open problem in condensed matter physics. We develop a recent approach to liquids from the solid state by accounti…
