Abstract We propose a thermodynamical definition of the vacuum energy density ρ vac, defined as 〈vac|T μν |vac〉 = − ρ vac g μν , in quantum field theory in flat Minkowski space in D spacetime dimensions, which can be computed in the limit

Abstract We construct an integrable physical model of a single particle scattering with impurities spread on a circle. The S-matrices of the scattering with the impurities are such that the quantized energies of this system, coming from the Bethe Ans

Abstract We propose a proper definition of the vacuum expectation value of the stress energy tensor 〈0| T μν | 0〉 for integrable quantum field theories in two spacetime dimensions, which is the analog of the cosmological constant in 4d. For a w

Abstract It is well understood that 2d conformal field theory (CFT) deformed by an irrelevant T T ¯ $$ T\overline{T} $$ perturbation of dimension 4 has universal properties. In particular, for the most interesting cases, the theory develops a singul

Abstract The S-matrix of the well-studied sinh-Gordon model possesses a remarkable strong/weak coupling duality b → 1/b. Since there is no understanding nor evidence for such a duality based on the quantum action of the model, it should be question

Abstract Background High-dose vitamin C is increasingly used for sepsis and more recently for coronavirus disease 2019 (COVID-19) infections. Proponents argue that the low cost and near perfect safety profile of vitamin C support its early adoption.

In a recent article we showed that the vacuum energy density in two spacetime dimensions for a wide variety of integrable quantum field theories has the form ρvac=−m2/2g where m is a physical mass and g is a generalized coupling, where in the free

Introduction Vasodilatory hypotension is common among intensive care unit (ICU) patients; vasopressors are considered standard of care. However, optimal mean arterial pressure (MAP) targets for vasopressor titration are unknown. The objective of the

In previous work, it was shown that if certain series based on sums over primes of non-principal Dirichlet characters have a conjectured random walk behavior, then the Euler product formula for its L-function is valid to the right of the critical lin

OBJECTIVES:Vasopressors are not recommended by current trauma guidelines, but recent reports indicate that they are commonly used. We aimed to describe the early hemodynamic management of trauma patients outside densely populated urban centers. METHO
