Yukawa's Pion, Low-Energy QCD and Nuclear Chiral Dynamics

A survey is given of the evolution from Yukawa's early work, via the understanding of the pion as a Nambu-Goldstone boson of spontaneously broken chiral symmetry in QCD, to modern developments in the theory of the nucleus based on the chiral effective field theory representing QCD in its low-energy limit.Comment: 21 pages, 13 figures.

Dense Baryonic Matter and Strangeness in Neutron Stars

Recent developments of chiral effective field theory (ChEFT) applications to nuclear and neutron matter are summarized, with special emphasis on a (non-perturbative) extension using functional renormalisation group methods. Topics include: nuclear thermodynamics, extrapolations to dense baryonic matter and constraints from neutron star observables. Hyperon-nuclear interactions derived from SU(3) will be discussed with reference to the "hyperon puzzle" in neutron star matter.Comment: 17 pages, 7 figures; invited talk at the Int. Conf. on Quarks and Nuclear Physics (QNP 2018), Tsukuba, Japan; to appear in JPS Conf. Pro

Chiral Dynamics in Nuclear Systems

A survey is given on selected topics concerning the role of spontaneous chiral symmetry breaking in low-energy QCD, and its dynamical implications for nuclear systems. This includes aspects of chiral thermodynamics (the temperature and density dependence of the chiral condensate). It also includes an update on the theory of low-energy (s-wave) pion-nuclear interactions relevant for deeply-bound states of pionic atoms and the quest for possible fingerprints of chiral symmetry restoration in nuclear systems.Comment: 16 pages, 5 figures, Proceedings CHIRAL 02, Kyoto, Japa

Political constraints on monetary policy during the Great Inflation

The U.S. Great Inflation of the 1970s was characterized by repeated, failed attempts at disinflation by the Federal Reserve as well as periods of inaction despite rising inflation. Previous research has attributed these failures to policymakers’ “misperceptions” about monetary policy and the macroeconomy. This paper argues instead that the Fed’s behavior during this period can be explained as a response to political constraints. Members of the Fed understood that a serious attempt to tackle inflation would be unpopular with the public and would generate opposition from Congress and the Executive branch. The result was a commitment to the policy of gradualism, under which the Fed would attempt to reduce inflation with mild policies that would not trigger an outright recession, and premature abandonment of anti-inflation policies at the first sign of recession. The Fed managed to disinflate successfully under Chairman Volcker only when the political constraints on Fed policy were lifted after 1979, allowing the Fed to abandon the policy of gradualism and knowingly take actions that risked recession. Evidence for this explanation of Fed behavior is found in Minutes and Transcripts of FOMC meetings and speeches of Fed chairmen
