On the compressibility of deformable spin chains in a vicinity of quantum critical points
Oleg Derzhko, Jozef Strecka, Lucia Galisova
We calculate the ground-state compressibility of a deformable spin-1/2 Heisenberg-Ising chain with Dzyaloshinskii-Moriya interaction to discuss how a quantum critical point inheren…
On the correlation properties of thermal noise in fluids
Vladimir Lisy, Jana Tothova, Lukas Glod
The properties of the thermal force driving micron particles in incompressible fluids are studied within the hydrodynamic theory of the Brownian motion. It is shown that the assump…
Magnetic properties of the spin-1/2 Ising-Heisenberg diamond chain with the four-spin interaction
Lucia Galisova
A symmetric spin-1/2 Ising-Heisenberg diamond chain with the Ising four-spin interaction is exactly solved by means of the generalized decoration-iteration mapping transformation.…
Brownian oscillators driven by correlated noise in a moving trap
Lukas Glod, Gabriela Vasziova, Jana Tothova +1
Brownian oscillator, i.e. a micron-sized or smaller particle trapped in a thermally fluctuating environment is studied. The confining harmonic potential can move with a constant ve…
