Supersolid phase of hard-core bosons on a triangular lattice.
We study properties of the supersolid phase observed for hard-core bosons on the triangular lattice near half-integer filling factor, and the phase diagram of the system at finite temperature. We find that the solid order is always of the (2m, -m, -m) with m changing discontinuously from positive to negative values at half filling, in contrast with phases observed for Ising spins in a transvers...

قاعده مقتضی و مانع در متون فقهی کم و بیش مستند احکام قرار گرفته و مورد مناقشه فقهاء و اصولیین می باشد و مشهور معتقند مقتضی و مانع، قاعده نیست بلکه یکی از مسائل ذیل استصحاب است لذا نگارنده بر آن شد تا پیرامون این قاعده پژوهش جامعی انجام دهد. به عقیده ما مقتضی دارای حیثیت مستقلی است و هر گاه می گوییم مقتضی احراز شد یعنی با ماهیت مستقل خودش محرز گشته و قطعا اقتضاء خود را خواهد داشت مانند نکاح که ...

متن کاملSupersolidity, entropy, and frustration: t-t -V model of hard-core bosons on the triangular lattice
We study the properties of t-t -V model of hard-core bosons on the triangular lattice that can be realized in optical lattices. By mapping to the spin-1 /2 XXZ model in a field, we determine the phase diagram of the t-V model where the supersolid characterized by the ordering pattern x ,x ,−2x “ferrimagnetic” or SS A is a ground state for chemical potential 3V. By turning on either temperature ...
متن کاملUnusual liquid state of hard-core bosons on the pyrochlore lattice.
We study the physics of hard-core bosons with unfrustrated hopping (t) and nearest-neighbor repulsion (V) on the three dimensional pyrochlore lattice. At half-filling, we demonstrate that the small V/t superfluid state eventually becomes unstable at large enough V/t to an unusual insulating state which displays no broken lattice translation symmetry. Equal time and static density correlators in...
