Algebraic approach to time-delay data analysis for LISA
As we have indicated in Sec. 1, a reason that often is put forward for rationalising the observed breakdowns of the Luttinger theorem, is the supposed failure of the weak-coupling many-body perturbation theory in correctly describing stronglycorrelated GSs.
On the Luttinger theorem concerning number of particles in the ground states of systems of interacting fermions
Rather, our above statement has direct bearing on the phenomenological theory of Landau in which idealised theoretical considerations merely provide a framework in which to rationalise the elements of the theory; within this framework, the stated conditions are more stringent than strictly necessary.
On the Luttinger theorem concerning number of particles in the ground states of systems of interacting fermions
Thus, taken together, very good quantitative accord with a whole host of spectral and transport responses for 1TTiSe2 and a comprehensive qualitative rationalisation of structural features in one single theoretical picture constitutes overwhelming support for a novel PEL view.
Preformed Excitons, Orbital Selectivity, and Charge-Density-Wave Order in 1T-TiSe_2
That this identification implies an interesting scenario, similar to those invoked for anomalous metals on the border of (T = 0) magnetism may also permit a rationalisation of the apparent ‘similarities’ claimed to exist between under-doped cuprates and TMD .
