", "abstract": "In 2000 Harter et al. reported the first measurements of the enhancement of the heat capacity \u0394CQ[equivalent]C(Q)-C(Q=0) of helium-II transporting a heat flux density Q near T\u03bb. Surprisingly, their measured \u0394CQ was ~7\u201312 times larger than predicted, depending on which theory was assumed. In this report we present a candidate explanation for this discrepancy: unintended heat flux inhomogeneity. Because C(Q) should diverge at a critical heat flux density Qc, homogeneous heat flow is required for an accurate measurement. We present results from numerical analysis of the heat flow in the Harter et al. cell indicating that substantial inhomogeneity occurred. We determine the effect of the inhomogeneity on \u0394CQ and find rough agreement with the observed disparity between prediction and measurement.", "date": "2006-09-07", "date_type": "published", "publisher": "American Institute of Physics", "place_of_pub": "Melville, NY", "pagerange": "133-134", "id_number": "CaltechAUTHORS:BOYaipcp06", "isbn": "0-7354-0347-3", "book_title": "International Conference on Low Temperature Physics, 24th, Orlando, FL, 10-17 August 2005", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:BOYaipcp06", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA", "grant_number": "NAG3-1763" }, { "agency": "NASA", "grant_number": "NAG3-2900" }, { "agency": "NASA/JPL", "grant_number": "960494" }, { "agency": "Gordon and Betty Moore Foundation" } ] }, "contributors": { "items": [ { "id": "Takano-Y.", "name": { "family": "Takano", "given": "Y." } }, { "id": "Hershfield-S-P", "name": { "family": "Hershfield", "given": "S.

", "abstract": "When a heat flux Q is applied downward through a sample of liquid 4He near the lambda transition, the helium self organizes such that the gradient in temperature matches the gravity induced gradient in Tlambda. All the helium in the sample is then at the same reduced temperature tSOC = ((T[sub SOC] - T[sub lambda])/T[sub lambda]) and the helium is said to be in the Self-Organized Critical (SOC) state. We have made preliminary measurements of the 4He SOC state specific heat, C[del]T(T(Q)). Despite having a cell height of 2.54 cm, our results show no difference between C[del]T and the zero-gravity 4He specific heat results of the Lambda Point Experiment (LPE) [J.A. Lipa et al., Phys. Rev. B, 68, 174518 (2003)] over the range 250 to 450 nK below the transition. There is no gravity rounding because the entire sample is at the same reduced temperature tSOC(Q). Closer to Tlambda the SOC specific heat falls slightly below LPE, reaching a maximum at approximately 50 nK below Tlambda, in agreement with theoretical predictions [R. Haussmann, Phys. Rev.

", "abstract": "The equilibrium phase diagrams of monolayers of many substances adsorbed on graphite have long been studied as examples of 2-dimensional (2D) matter. One typically observes 2D gas and liquid phases, and solid phases that may be commensurate or incommensurate with the substrate lattice. Many experimental techniques have been used, but thermodynamic measurements are generally the most useful for tracing out phase boundaries.\n\nRecent advances in technique have made it possible to use thermodynamic measurements to study the phase diagrams of the second and higher layers, up to the fifth or sixth. These advances include ultra high resolution scanning calorimetry, and a detailed understanding of the role of capillary condensation in corners and pores of the graphite foam substrate. We find a rich array of phases and phase transitions in multilayer methane, argon and krypton. The second and third layers typically have distinct 2D gas, liquid and solid phases evidenced by 2D triple points and critical points. We observe phase transitions between solid phases that are commensurate and incommensurate with the layer below. We also observe melting of the first layer at higher temperatures, even when one to five additional layers are adsorbed on top of it.\n\nIn argon and krypton, but not in methane, a strange new phenomenon is observed at temperatures above the gas-liquid critical point of the nth layer for n> 3. Below that temperature, nthlayer gas coexists with a condensed nth layer. At some temperature above it, a new coexistence region is observed in which a partial nth layer coexists with a partial n + 1st layer. This behavior is thought to be evidence for a theoretically predicted phase transition of the bulk interface, called the preroughening transition.", "date": "1992", "date_type": "published", "publisher": "Materials Research Society", "place_of_pub": "Pittsburgh, MA", "pagerange": "319-326", "id_number": "CaltechAUTHORS:20151217-082051420", "isbn": "9781107409590", "book_title": "Evolution of Surface and Thin Film Microstructure", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20151217-082051420", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "Department of Energy (DOE)", "grant_number": "DE-FG03-85ER45192" } ] }, "doi": "10.1557/PROC-280-319", "primary_object": { "basename": "DavidGoodsteinetal.PDF", "url": "https://authors.library.caltech.edu/records/6hb1f-jr459/files/DavidGoodsteinetal.PDF" }, "resource_type": "book_section", "pub_year": "1992", "author_list": "Goodstein, David; Day, P.; et el." }, { "id": "https://authors.library.caltech.edu/records/we5c0-8hk54", "eprint_id": 63025, "eprint_status": "archive", "datestamp": "2023-08-19 23:30:09", "lastmod": "2024-01-13 16:29:47", "type": "book_section", "metadata_visibility": "show", "creators": { "items": [ { "id": "Goodstein-D-L", "name": { "family": "Goodstein", "given": "D.

The authors of the phase diagram had to confront some of the most interesting and vexing issues in the field of adsorbed films today: Does the adsorbed solid wet the substrate, and if so, why? Is there evidence of roughening, capillary condensation, or surface melting? Most intriguing of all, can one observe a dimensional crossover, from 2D to 3D behavior in the melting transition? The authors proposed answers to all of those questions.
