One-dimensionally confined ammonia molecules: A theoretical study
Maksym Druchok, Volodymyr Krasnov, Taras Krokhmalskii +1
We examine a single-file chain of ammonia molecules in a carbon nanotube. To this end, we use i) molecular dynamics simulations (combined with the charges for ammonia nitrogen and…
Towards a quasiphase transition in the single-file chain of water molecules: Simple lattice model
Maksym Druchok, Volodymyr Krasnov, Taras Krokhmalskii +4
Recently, X.Ma et al. [Phys. Rev. Lett. 118, 027402 (2017)] have suggested that water molecules encapsulated in (6,5) single-wall carbon nanotube experience a temperature-induced q…
Low-temperature thermodynamics of the two-leg ladder Ising model with trimer rungs: A mystery explained
Taras Hutak, Taras Krokhmalskii, Onofre Rojas +2
Recently, a surprising low-temperature behavior has been revealed in a two-leg ladder Ising model with trimer rungs (Weiguo Yin, arXiv:2006.08921). Motivated by these findings, we…
Towards low-temperature peculiarities of thermodynamic quantities for decorated spin chains
Taras Krokhmalskii, Taras Hutak, Onofre Rojas +2
We discuss the origin of an enigmatic low-temperature behavior of one-dimensional decorated spin systems which was coined the pseudo-transition. Tracing out the decorated parts res…
Quantum Phase Transitions in Spin-1/2 Ising Chain in Regularly Alternating Transverse Field: Spin Correlation Functions
Oleg Derzhko, Taras Krokhmalskii
We consider the spin-1/2 Ising chain in a regularly alternating transverse field to examine the effects of regular alternation on the quantum phase transition inherent in the quant…
Regularly alternating spin-1/2 anisotropic XY chains: The ground-state and thermodynamic properties
Oleg Derzhko, Johannes Richter, Taras Krokhmalskii +1
Using the Jordan-Wigner transformation and continued fractions we calculate rigorously the thermodynamic quantities for the spin-1/2 transverse Ising chain with periodically varyin…
