Torleif Erik Oskar Ericson (born November 2, 1930) is a Swedish

Ericson-Ericson Lorentz-Lorenz effect'.[5] His research has nurtured the link between nuclear and particle physics
.

Biography

Career

Ericson studied physics at Lund University, from where he obtained his PhD,[6] under the supervision of Ben Mottelson at the Nordic Institute for Theoretical Physics (Nordita), in 1958.

Ericson held positions as a

Berkeley[3][8]
from 1959 to 1960.

Following he joined CERN’s Theory Division,[9] first as a fellow, and then as a staff member in 1962.[10] He was recruited by the Director-General, V. F. Weisskopf, as the theoretical interface between particle and nuclear physics.[2]

Sabbatical year 1969/70 at MIT.

Invited guest professor at

Louvain, Tokyo and Uppsala
.

Adjunct professor at Uppsala University from 1993 within the framework of CERN's collaboration with Member States.

Official retirement from CERN in 1995,[11] but still emeritus.[12]

Research contributions

Moving from MIT to Berkeley he wrote two papers[3][4] in which he predicted what later became known as 'Ericson fluctuations' and today is considered a prime example of quantum chaos.[8][13] Initially the idea was met with resistance. However, the prediction stimulated in a large number of nuclear reaction studies, as reviewed a few years later with Mayer-Kuckuk,[14] and Ericson continued to develop the consequences in depth in a series of articles.[15]

In 1963, Ericson, after an initiative by A. de-Shalit and V.F. Weisskopf, organised an international conference on high-energy physics and nuclear structure.[16] The meeting turned out to be of significant importance both for Ericson's own career and the development of this field, as a new branch of nuclear physics.[1][15][17] The conference series, later generally referred to as PANIC, was the start of the field interfacing nuclear and particle physics and has developed into a triennial event. The series is sponsored by the International Union of Pure and Applied Physics and has been going on since then.[18]

In the 1960's much information in this field came from

Ericson-Ericson Lorentz-Lorenz effect' and has later influenced other areas of many-body physics.[15]

His interest in the quantitatively limits of pion physics in nuclei produced some of the most accurate and parameter-free descriptions of observables in the entire nuclear physics.[15][19]

He took interest in many different areas of physics. Together with

T-violation in nuclei based on fluctuations,[3] as well as an accurate empirical bound for anti-gravity.[22]

The activity on the interface between nuclear and particle physics led to that CERN set up various scientific committees,[23] in which Ericson was deeply involved.

Administrative activities

In his role as chairman of the Nuclear Structure Committee, Ericson proposed in 1964, to build an on-line isotope separator, which later has become known as

ISOLDE.[24][25][26] CERN eventually established its ultrarelativistic heavy-ion programme[27] that over the years has attracted a large number of experimental physicists to the laboratory.[28][29]

In addition to carry out his research, Ericson has taken on a series of managerial tasks. For several periods he filled the role as deputy leader for the CERN Theory Division, he chaired the CERN Nuclear Structure Committee, served as a member of the CERN Physics III Committee, Swedish Program Committee for Physics and in the

Nuclear Physics A, with responsibility for intermediate energy, from 1976 to 2000.[30][31] Since 1991 he is one of the general editors of the series Cambridge Monographs on Particle Physics, Nuclear Physics and Cosmology.[32][33]
Ericson has also been editor for a large number of conference proceedings.

Awards and honors

Private life

Ericson is married to the French physicist Magda Ericson since 1957. Together they have two adult children. The Ericsons reside in Geneva, Switzerland.[37]
