The onishi formula
Did you know?
WebIn principle, N(q;q0) can be calculated with the Onishi formula [3,4]. However, the formula undetermines the sigh of N(q;q0). To solve this “sign problem”, various approaches were proposed to date. Hara, Hayashi and Ring proposed a method based on the continuity of the norm overlap kernel as a function of the generator coordinate q[5]. Webdue to Onishi and Yoshida, has a more limited scope and no sign problem. I give a short proof of the latter, whose derivation is missing in the paper by Onishi and Yoshida, and a new, combinatoric, proof of an equivalent formula recently derived by Robledo. I. INTRODUCTION Bogolyubov quasi-nucleon vacua and their overlap am-
WebThe Onishi formula [4,5] is the first expression of the overlap between two different HFB vacua, but the sign of the overlap is not determined. Many works have been done to overcome this sign problem [6–14]. In Ref. [14], Rob-ledo made the final solution and proposed a new formula using WebThe Onishi formula was first obtained by Onishi and Yoshida [1], and Onishi and his collaborators used the linked cluster expansion [13] for the double-variational method [14], [15]. Here, we ...
