Exceptional points in classical spin dynamics. [PDF]
Sci Rep, 2019 AbstractNon-conservative physical systems admit a special kind of spectral degeneracy, known as exceptional point (EP), at which eigenvalues and eigenvectors of the corresponding non-Hermitian Hamiltonian coalesce. Dynamical parametric encircling of the EP can lead to non-adiabatic evolution associated with a state flip, a sharp transition between the ...

CLASSICAL RELATIVISTIC SPIN PARTICLES [PDF]
Condensed Matter Physics, 1998 Relativistic spin particles are approached from the stand point of Hamiltonian actions of Poincare group on itself. The several possible solutions are classified and realizations are given in terms of Dirac???s constraints formalism.

Semi-classical simulation of spin-1 magnets
Physical Review Research, 2022 Theoretical studies of magnets have traditionally concentrated on either classical spins, or the extreme quantum limit of spin-1/2. However, magnets built of spin-1 moments are also intrinsically interesting, not least because they can support quadrupole,

Symbol correspondences for spin systems [PDF]
, 2014 The present monograph explores the correspondence between quantum and classical mechanics in the particular context of spin systems, that is, SU(2)-symmetric mechanical systems.

Decay of spin-spin correlations in disordered quantum and classical spin chains
Physical Review Research, 2020 The real-time dynamics of equal-site correlation functions is studied for one-dimensional spin models with quenched disorder. Focusing on infinite temperature, we present a comparison between the dynamics of models with different quantum numbers S=1/2,1 ...

The classical nature of nuclear spin noise near clock transitions of Bi donors in silicon [PDF]
, 2015 Whether a quantum bath can be approximated as classical noise is a fundamental issue in central spin decoherence and also of practical importance in designing noise-resilient quantum control.

Recovering Classical Dynamics from Coupled Quantum Systems Through Continuous Measurement [PDF]
, 2003 We study the role of continuous measurement in the quantum to classical transition for a system with coupled internal (spin) and external (motional) degrees of freedom.

Multi-$Q$ hexagonal spin density waves and dynamically generated spin-orbit coupling: time-reversal invariant analog of the chiral spin density wave [PDF]
, 2016 We study hexagonal spin-channel ("triplet") density waves with commensurate $M$-point propagation vectors. We first show that the three $Q=M$ components of the singlet charge density and charge-current density waves can be mapped to multi-component $Q=0$
