We employ both standard (SMC) and a more sophisticated replica exchange (REMC) Monte Carlo simulations in effort to demonstrate the difficulties of using the former and advantages of using the latter approaches. The ground state of the system is highly degenerate and consists of frozen superantiferromagnetic (SAF) domains, separated by zero-energy domain walls (ZEDW), thus showing no conventional long-range ordering. We demonstrate that such states are difficult to access by using SMC due to complex multimodal energy landscape, characteristic for such systems. On the other hand, the REMC approach turns out to be more efficient in exploring it and thus reaching also states not accessible to SMC. At finite temperatures, the system shows a peculiar behavior with multiple anomalies in thermodynamic functions, which can be attributed to the transitions between several states with the SAF-like ordering characterized by different types of ZEDW.<\/jats:p>","DOI":"10.7148\/2022-0336","type":"proceedings-article","created":{"date-parts":[[2022,8,10]],"date-time":"2022-08-10T17:29:18Z","timestamp":1660152558000},"page":"336-341","source":"Crossref","is-referenced-by-count":0,"title":["Massive Degeneracy and Anomalous Thermodynamics in a Highly Frustrated Ising Model on Honeycomb Lattice"],"prefix":"10.7148","author":[{"given":"Milan","family":"Zukovic","sequence":"first","affiliation":[]}],"member":"4144","published-online":{"date-parts":[[2022,6,3]]},"event":{"name":"36th ECMS International Conference on Modelling and Simulation"},"container-title":["ECMS 2022 Proceedings edited by Ibrahim A.
