Journal of Low Temperature Physics - Outstanding Reviewers

This page is dedicated to the exceptional contributions of some of our referees that have reviewed for the Journal of Low Temperature Physics. The referees highlighted here have gone beyond the normal expectations in terms of the depth and the timeliness of their reports, the details of their analyses, and the extent to which their comments have helped our authors to improve their work. However, we must note that for every named reviewer there are many more who have also made significant contributions to the peer review process and we are equally thankful to them. We hope that by highlighting a few of our most outstanding reviewers, we can inspire our authors and readers about the invaluable contribution of peer reviewers to the academic publishing process.

This list will be updated annually, to recognize and acknowledge some of the outstanding reviewers for the preceding year.


Outstanding Reviewers of 2021

John Beamish

New Content Item

Since he was a Ph.D. student, John Beamish has studied quantum fluids and solids, particularly solid helium.  He was a postdoc at Brown University and a faculty member at the University of Delaware before returning to Canada.  At the University of Alberta his group studied superfluidity and freezing in small pores.  Since 2005, his experiments have focused on solid helium’s elastic properties and he was elected as a Fellow of the American Physical Society in recognition of this work. He has spent sabbatical leaves with Moses Chan’s group at Penn State, Jeevak Parpia’s lab at Cornell and Sebastien Balibar’s group at ENS Paris. Since 2019, John has been an emeritus Professor at the University of Alberta where he continues to run a low temperature physics laboratory, review papers and to sit on the Editorial Board of the Journal of Low Temperature Physics.


William P. Halperin

New Content Item

William P. Halperin is a Canadian-American physicist, academic, and researcher. He is the Orrington Lunt Professor of Physics at Northwestern University.  Halperin is an experimentalist in condensed matter physics specializing in ultra-low temperature investigations of quantum liquids and solids, notably liquid and solid 3He, superconducting quantum materials and unconventional superconductivity, notably UPt3, magnetic compounds, highly porous materials including aerogels, porous glasses and cements. He has developed specialized acoustic techniques for very low temperatures as well as applications of nuclear magnetic resonance for very high magnetic fields. In 2017 he was awarded the Fritz London Memorial Prize and has served as chair of the Low Temperature Commission of International Union of Pure and Applied Physics from 2017 to 2021.


Matti Krusius

New Content Item

Matti Krusius is a low-temperature researcher and academic teacher who has been employed during his career at the University of Technology in Helsinki, University of California in San Diego, University of Turku, Los Alamos National Laboratory in New Mexico, and Aalto University in Espoo. He studied hyperfine interactions in rare earth metals with calorimetric techniques as his doctoral thesis work. Since then, his research has mainly dealt with superfluids and superconductors at the lowest temperatures. At the center of interest have been quantized vortices and superfluid dynamics in the various helium-3 superfluid phases, both in the laminar and turbulent regimes of superfluid flow. The measurements are primarily performed with nuclear magnetic resonance in a rotating cryostat with adiabatic nuclear demagnetization cooling at temperatures below 3 mK. The latest work has been on the excitation dynamics in the zero-temperature limit of these systems.


William J. Mullin

New Content Item

William J. Mullin is Professor Emeritus at the University of Massachusetts Amherst. He is a widower with three children and seven grandchildren. His areas of research are quantum fluids and the foundations of quantum mechanics. His most recent work involves the progressive collapse of a cat state made up of dual Bose-Einstein condensates as measurements are made one particle at a time.  He is author of “Quantum Weirdness” (Oxford, 2017) a book for a popular audience focusing on some of the more unusual aspects of quantum mechanics. He also has strong interests in the archaeology of the Ancestral Pueblo Indians of southwestern US. 


Petriina Paturi

New Content Item

Petriina Paturi is a professor of experimental condensed matter physics at the Wihuri Physical Laboratory, Department of Physics and Astronomy, University of Turku, Finland. Her research has mainly concentrated on high-temperature superconductor thin films and magnetic manganite perovskites. She has studied the magnetic flux pinning in YBCO and possibilities of enhancing the critical current by means of artificial pinning centres. Recently, her group has also shown that GdCaMnO is a good material for memristor applications. In addition to research, she is interested in science education at all levels and is the vice dean of education in the Faculty of Science of University of Turku.
