Nonequilibrium response of an electron mediated charge-density-wave-ordered material to a large dc electric field

O. P. Matveev, A. M. Shvaika, T. P. Devereaux +1

Using the Kadanoff-Baym-Keldysh formalism, we employ nonequilibrium dynamical mean-field theory to exactly solve for the nonlinear response of an electron-mediated charge-density-w…

Effective low-energy description of almost Ising-Heisenberg diamond chain

Oleg Derzhko, Olesia Krupnitska, Bohdan Lisnyi +1

We consider a geometrically frustrated spin-1/2 Ising-Heisenberg diamond chain, which is an exactly solvable model when assuming part of the exchange interactions as Heisenberg one…

ESR modes in a Strong-Leg Ladder in the Tomonaga-Luttinger Liquid Phase

M. Ozerov, M. Maksymenko, J. Wosnitza +6

Magnetic excitations in the strong-leg quantum spin ladder compound (CHN)CuBr (known as DIMPY) in the field-induced Tomonaga-Luttinger spin liquid phase are stud…

Nonequilibrium dynamical mean-field theory for the charge-density-wave phase of the Falicov-Kimball model

O. P. Matveev, A. M. Shvaika, T. P. Devereaux +1

Nonequilibrium dynamical mean-field theory (DMFT) is developed for the case of the charge-density-wave ordered phase. We consider the spinless Falicov-Kimball model which can be so…

Magnetism-driven ferroelectricity in spin-1/2 chains

Oleg Menchyshyn, Vadim Ohanyan, Taras Verkholyak +2

We illustrate the magnetoelectric effect conditioned by the Katsura-Nagaosa-Balatsky (KNB) mechanism within the frames of exactly solvable spin-1/2 chains. Due to three-spin i…

Strongly correlated flat-band systems: The route from Heisenberg spins to Hubbard electrons

Oleg Derzhko, Johannes Richter, Mykola Maksymenko

In this review we recapitulate the basic features of the flat-band spin systems and briefly summarize earlier studies in the field. Main emphasis is made on recent developments whi…
