Reweighting Scheme for the Calculation of Grand‐Canonical Expectation Values in Quantum Monte Carlo Simulations With a Fermion Sign Problem

Contributions to Plasma Physics, EarlyView.
ABSTRACT Ab initio path integral Monte Carlo (PIMC) simulations constitute the gold standard for the estimation of a broad range of equilibrium properties of a host of interacting quantum many‐body systems spanning a broad range of conditions from ultracold atoms to warm dense quantum plasmas.

3d N $$ \mathcal{N} $$ = 4 OPE coefficients from Fermi gas

Journal of High Energy Physics, 2020
The partition function of a 3d N $$ \mathcal{N} $$ = 4 gauge theory with rank N can be computed using supersymmetric localization in terms of a matrix model, which often can be formulated as an ideal Fermi gas with a non-trivial one-particle Hamiltonian.

b → cτ ν ¯ $$ \overline{\nu} $$ e,μ contributions to R(D(*))

Journal of High Energy Physics, 2022
The R(D (*)) puzzle stands for a ~ 3σ violation of lepton flavor universality between the decay rates of B → D (*) τν and B → D (*) ℓν, where ℓ = e, μ. If it is accounted for by new physics, there is no reason in general that the relevant neutrinos are ...

Modification to the Hawking temperature of a dynamical black hole by a flow-induced supertranslation

Journal of High Energy Physics, 2020
One interesting proposal to solve the black hole information loss paradox without modifying either general relativity or quantum field theory, is the soft hair, a diffeomorphism charge that records the anisotropic radiation in the asymptotic region. This

Astrophysics and elementary particles

Journal of Physics: Conference Series, 2005
These are the lecture notes of an astroparticle course constructed from the local astrophysical environment out to the cosmological domain. The subjects reviewed are stellar physics, focusing on the standard solar model and the case of solar neutrinos; the Galactic interstellar medium and the origin of its cosmic rays; the more energetic extragalactic ...

Squashing, mass, and holography for 3d sphere free energy

Journal of High Energy Physics, 2021
We consider the sphere free energy F(b; m I ) in N $$ \mathcal{N} $$ = 6 ABJ(M) theory deformed by both three real masses m I and the squashing parameter b, which has been computed in terms of an N dimensional matrix model integral using supersymmetric ...
