Quantum matter hosts a large variety of phases, some coexisting, some competing; when two or more orders occur together, they are often entangled and cannot be separated. Dynamical multiferroicity, where fluctuations of electric dipoles lead to magnetization, is an example where the two orders are impossible to disentangle. Here we demonstrate an elevated magnetic response of a ferroelectric near the ferroelectric quantum critical point (FE QCP), since magnetic fluctuations are entangled with…

Finite temperature effects in quantum systems with competing scalar orders

It is obtained that Tc decreases as a function of the distance to the zero temperature classical bicritical point (ZTCBP) in the coexistence region, implying that in this approach, the system attains the highest Tc above the fine tuned value of this ZTCBP.

Dynamical Magnetic Field Accompanying the Motion of Ferroelectric Domain Walls.

An expression for the dynamical magnetic field is developed and the relevant parameters for the example of 90° and 180° domain walls, as well as for polar skyrmions, in BaTiO_{3}, using a combination of density functional theory and phenomenological modeling.

Melting of charge order in the low-temperature state of an electronic ferroelectric-like system

Strong electronic interactions can drive a system into a state with a symmetry breaking. Lattice frustration or competing interactions tend to prevent symmetry breaking, leading to quantum disordered

Dynamical topology in ferroelectric nanostructures by 12[11¯0](110) dislocations in SrTiO3

Dynamical topology in ferroelectrics such as polarization rotation begins to attract interest because it brings new opportunities to generate properties that the static states cannot achieve.

Orbital magnetic moments of phonons

In ionic materials, circularly polarized phonons carry orbital magnetic moments that arise from circular motions of the ions, and which interact with other magnetic moments or fields. Here, we

Quantum criticality in a uniaxial organic ferroelectric

The nature of long-range dipole interactions in uniaxial materials, which lead to non-analytical terms in the free-energy expansion in the polarization, predict a dielectric susceptibility varying as 1/T(3)close to the quantum critical point, but this is not found.

Quantum Critical Origin of the Superconducting Dome in SrTiO_{3}.

A model in which the soft mode fluctuations provide the pairing interaction for superconductivity carriers is suggested, and it is predicted that the highest critical temperature will increase and shift to lower carrier doping with increasing ^{18}O isotope substitution, a scenario that is experimentally verifiable.

The solution of this model in (2+1)D reveals that the critical fluctuations are determined by topological excitations, vortices and a variety of instantons, and not by renormalized spin-wave theories of the Landau-Ginzburg-Wilson type, adapted by Moriya, Hertz and others for quantum-criticality.
