Coherent and thermal coherent state
Journal of Mathematical Physics, 1989The characterization of coherent states as the quantum states that split into two uncorrelated beams is considered. The characterization leads to the study of coherent states at finite temperature—thermal coherent states (TCS’s). These TCS’s are defined within the formalism of thermo field dynamics (TFD).

Abstract This chapter defines and determines the properties of the important (though non-physical) boson and fermion coherent states, which are specified in terms of c-number (bosons) or Grassmann (fermions) variables and their complex conjugates, and defined via unitary displacement operators acting on the vacuum state.

Multidimensional generalized coherent states
Journal of Physics A: Mathematical and General, 2002Summary: Generalized coherent states were presented recently for systems with one degree of freedom having discrete and/or continuous spectra. We extend that definition to systems with several degrees of freedom, give some examples and apply the formalism to the model of two-dimensional fermion gas in a constant magnetic field.

The definition of coherent states for an arbitrary Lie group G is reviewed in the first two sections, and the original Glauber coherent states are exhibited as the particular case in which G is the Weyl group. The question of how the formalism is altered under perturbations of the Hamiltonian is addressed in section 3.

Coherence of Superposition States*
Communications in Theoretical Physics, 2019Abstract We find tight upper bound on the coherence of a superposition of two states in terms of the coherence of the two states constituting the superposition with l 1-norm of coherence. Our upper bound is tighter than the one presented by Liu, et al. [Quantum Inf. Process.
