Compared with other extended theories, we stress that any realistic theory of gravity must have physical ground states when quantization is performed. To fulfill the three conditions, we softly break the detailed balance but keep its basic structure unchanged. It turns out that the new model constructed in this way can avoid the strong coupling problem and remains power-counting renormalizable, moreover, it has a stable vacuum state by an appropriate choice of parameters.<\/jats:p>","DOI":"10.3390\/sym13010100","type":"journal-article","created":{"date-parts":[[2021,1,10]],"date-time":"2021-01-10T23:03:42Z","timestamp":1610319822000},"page":"100","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Extended Ho\u0159ava Gravity with Physical Ground-State Wavefunction"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0752-6457","authenticated-orcid":false,"given":"Fu-Wen","family":"Shu","sequence":"first","affiliation":[{"name":"Department of Physics, Nanchang University, Nanchang 330031, China"},{"name":"Center for Relativistic Astrophysics and High Energy Physics, Nanchang University, Nanchang 330031, China"},{"name":"GCAP-CASPER, Physics Department, Baylor University, Waco, TX 76798-7316, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tao","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Physics, Nanchang University, Nanchang 330031, China"},{"name":"Center for Relativistic Astrophysics and High Energy Physics, Nanchang University, Nanchang 330031, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,1,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"084008","DOI":"10.1103\/PhysRevD.79.084008","article-title":"Quantum Gravity at a Lifshitz Point","volume":"79","author":"Horava","year":"2009","journal-title":"Phys.
