Renormalization-group study of the four-body problem

Renormalization Group Methods for the Nuclear Many-Body Problem

The application of renormalization group (RG) methods to microscopic nuclear many-body calculations is discussed. We present the solution of the RG equations in the particle-hole channels for neutron matter and the application to S-wave pairing. Furthermore, we point out that the inclusion of tensor and spin-orbit forces leads to spin non-conserving effective interactions in nuclear matter. The...

the problem of divine hiddenness

این رساله به مساله احتجاب الهی و مشکلات برهان مبتنی بر این مساله میپردازد. مساله احتجاب الهی مساله ای به قدمت ادیان است که به طور خاصی در مورد ادیان ابراهیمی اهمیت پیدا میکند. در ادیان ابراهیمی با توجه به تعالی خداوند و در عین حال خالقیت و حضور او و سخن گفتن و ارتباط شهودی او با بعضی از انسانهای ساکن زمین مساله ای پدید میاید با پرسشهایی از قبیل اینکه چرا ارتباط مستقیم ویا حداقل ارتباط وافی به ب...

Renormalization - Group Study of Four - Dimensional Su ( 4 ) Gauge Theory

In some recent papers, we studied pure SU(4) gauge theory with the Wilson action on a hypercubical lattice in four space t ime dimensions and found a firstorder phase transition at/3 = 10.2 [1 ], that this phase transition was not deconfining [2] and measured the asymptotic freedom scale parameter A 0 [2]. In the present paper, we wish to apply a renormalizationgroup scheme [3] for comparing th...

Similarity Renormalization Group for Few-Body Systems

Internucleon interactions evolved via flow equations yield soft potentials that lead to rapid variational convergence in few-body systems. The Similarity Renormalization Group (SRG) [1, 2] provides a compelling method for evolving internucleon forces to softer forms by decoupling lowfrom high-momentum matrix elements [3, 4]. A series of unitary transformations parameterized by s (or λ ≡ s−1/4) ...
