High temperature expansion of double scaled SYK

چکیده
We study the high temperature (or small inverse $\beta$) expansion of free energy double scaled SYK model. find that this is a convergent series with finite radius convergence. It turns out convergence determined by first zero partition function on imaginary $\beta$-axis. also show semi-classical obtained from saddle point approximation exact result consistent energy.

Convergence of Scaled Delta Expansion: Anharmonic Oscillator
We prove that the linear delta expansion for energy eigenvalues of the quantum mechanical anharmonic oscillator converges to the exact answer if the order dependent trial frequency Ω is chosen to scale with the order as Ω = CN ; 1/3 < γ < 1/2, C > 0 as N → ∞. It converges also for γ = 1/3, if C ≥ αcg, αc ≃ 0.570875, where g is the coupling constant in front of the operator q/4. The extreme case...
متن کاملHigh Temperature Expansion for a Chain Model
We consider an arbitrary translationally invariant chain model, with nearest neighbors interaction and satisfying periodic boundary condition. The approach developed here allows a thermodynamic description of the chain model directly in terms of grand potential per site. This thermodynamic function is derived from an auxiliary function constructed only from open connected sub-chains. To exempli...
متن کاملHigh-temperature superfluidity in double-bilayer graphene.
Exciton bound states in solids between electrons and holes are predicted to form a superfluid at high temperatures. We show that by employing atomically thin crystals such as a pair of adjacent bilayer graphene sheets, equilibrium superfluidity of electron-hole pairs should be achievable for the first time. The transition temperatures are well above liquid helium temperatures. Because the sampl...

متن کاملHigh Temperature Resummation in the Linear δ-Expansion
The optimized linear δ-expansion is applied to the λφ theory at high temperature. Using the imaginary time formalism the thermal mass is evaluated perturbatively up to order δ. A variational procedure associated with the method generates nonperturbative results which are used to obtain the critical temperature for the phase transition. Our results are compared with the ones given by propagator ...
