Energy saving approximation of Wiener process under unilateral constraints
M. A. Lifshits, S. E. Nikitin
We consider the energy saving approximation of a Wiener process under unilateral constraints. We show that, almost surely, on large time intervals the minimal energy necessary for…
Confinement of many-body Bethe strings
Jiahao Yang, Tao Xie, S. E. Nikitin +2
Based on Bethe-ansatz approach and inelastic neutron scattering experiments, we reveal evolution of confinement of many-body Bethe strings in ordered regions of quasi-one-dimension…
Complete field-induced spectral response of the spin-1/2 triangular-lattice antiferromagnet CsYbSe
Tao Xie, A. A. Eberharter, Jie Xing +14
Fifty years after Anderson's resonating valence-bond proposal, the spin-1/2 triangular-lattice Heisenberg antiferromagnet (TLHAF) remains the ultimate platform to explore highly en…
Slow spin dynamics and quantum tunneling of magnetization in the dipolar antiferromagnet DyScO
N. D. Andriushin, S. E. Nikitin, G. Ehlers +1
We present a comprehensive study of static and dynamic magnetic properties in the Ising-like dipolar antiferromagnet (AFM) DyScO\ by means of DC and AC magnetization measuremen…
Frustration model and spin excitations in the helimagnet FeP
A. S. Sukhanov, Y. V. Tymoshenko, A. A. Kulbakov +14
The metallic compound FeP belongs to the class of materials that feature a complex noncollinear spin order driven by magnetic frustration. While its double-helix magnetic structure…
Large Deviations of Telecom Processes
M. A. Lifshits, S. E. Nikitin
We study large deviation properties of Telecom processes appearing as limits in a critical regime of infinite source Poisson models.
