{"arxiv_id":"hep-lat/0409118","title":"Mobius Fermions: Improved Domain Wall Chiral Fermions","abstract":"A new class of domain wall fermions is defined that interpolates between Shamir's and Bori\\c{c}i's form without increasing the number of Dirac applications per CG iteration. This class represents a full (real) M\\\"obius transformation of the Wilson kernel. Simulations on quenched Wilson lattices with $\\beta = 6.0$ show that the number of lattice sites ($L_s$) in the fifth dimension can be reduced by a factor of 2 or more at fixed value of chiral symmetry violations measured by the residual mass ($m_{res}$).","primary_cat":"hep-lat","cross_cats":[],"submitted_at":"2004-09-19T03:18:32+00:00","latest_version":1,"source":"arxiv","source_label":"arXiv","source_url":null,"has_pdf":true,"has_source":false,"verdict":"CONDITIONAL","confidence":"MODERATE","one_line_summary":"A one-parameter generalization of domain wall fermions, the Möbius kernel, reaches the same residual chiral symmetry breaking with roughly half the fifth-dimension length in quenched tests.","novelty_score":6.0,"correctness_risk":"medium","formal_verification":"none","upvotes":0,"downvotes":0,"pith_score":0.0,"inbound_count":15,"_links":{"html":"https://pith.science/paper/hep-lat/0409118","verdict":"/api/v1/verdicts/hep-lat/0409118"}}
