Breathing Modes in Rotating Bose-Condensed Gas: An Exact Diagonalization Study

We present an exact diagonalization study of the breathing mode collective excitations for a rotating Bose-Einstein condensate of $N=10$ spinless bosons interacting via repulsive finite-range Gaussian potential and harmonically confined in quasi-two-dimension. The yrast state and the low-lying excited states are variationally obtained in given subspaces of the quantized total angular momentum $L$ employing the beyond lowest Landau level approximation in slowly rotating regime with $0 \le L < 2N$. For a given $L$, the low-energy eigenspectra (bands) are obtained in weakly to moderately interacting regime. Further, for a given interaction, the split in low-lying eigenenergies with increasing $L$ is the precursor to spontaneous symmetry breaking of the axisymmetry associated with the entry of the first vortex. With increase in repulsive interaction, the value of the first breathing mode increases for stable total angular momentum states L=0~\mbox{and}~N, but decreases for intermediate $0<L<N$ metastable states. The position of the observed first breathing modes in the eigenspectrum remains unchanged as the interaction is varied over several orders of magnitude.Comment: 5 pages, 3 figures, RevTex two colum

Novel phases in rotating Bose-condensed gas: vortices and quantum correlation

We present the exact diagonalization study of rotating Bose-condensed gas interacting via finite-range Gaussian potential confined in a quasi-2D harmonic trap. The system of many-body Hamiltonian matrix is diagonalized in given subspaces of quantized total angular momentum to obtain the lowest-energy eigenstate employing the beyond lowest-Landau-level approximation. In the co-rotating frame, the quantum mechanical stability of angular momentum states is discussed for the existence of phase transition between the stable states of interacting system. Thereby analyzing the von Neumann entanglement entropy and degree of condensation provide the information about quantum phase correlation in the many-body states. Calculating the conditional probability distribution, we further probe the internal structure of quantum mechanically stable and unstable states. Much emphasis is put on finding the spatial correlation of bosonic atoms in the rotating system for the formation and entry of singly quantized vortices, and then organizing into canonical polygons with and without a central vortex at the trap center. Results are summarized in the form of a movie depicting the vortex patterns having discrete p-fold rotational symmetry with $p = 2,3,4,5,6$.Comment: Updated version with 12 pages and 25 figures.

Measuring Transport Resilience: A Manawatu-Wanganui Region Case Study

The resilience of transport networks is attracting greater scrutiny at the international, national and sub-national levels. This research report explores the current state of knowledge about measuring transport resilience and presents a case study to address the question is: How resilient is the road and rail infrastructure in the Manawatu-Wanganui Region? This region in New Zealand’s lower North Island provides an interesting case study due to its strategic location in the North Island’s and indeed New Zealand’s transport network. In addition, it has experienced significant disruptions in the recent past, most notably widespread failures caused by flooding in 2004, and the lengthy closure of a significant inter-regional road connection, the Manawatu Gorge State Highway 3 road, due to a landslide in 2011-2012. It also provides an opportunity to explore this topic outside of a major metropolitan region. The region’s transport networks and infrastructure also have important social and economic functions. This research report is structured around a proposed Transport Resilience Indicator Framework (RIF) which explores six key dimensions of transport infrastructure resilience: engineering, services, ecological, social, economic and institutional. This holistic approach to measuring transport resilience and is envisaged to accommodate both qualitative and quantitative indicators. Within this framework, data were gathered via analysis of secondary sources and nine key informant interviews. The interview participants were from public sector agencies responsible for managing aspects of the region’s transport network, the private sector and one social service provider. The participants had considerable knowledge relating to the planning of the road network and/or its economic and social significance. They also had knowledge of the impacts and/or management of recent disruptions. The institutions responsible for managing the region’s transport network can identify vulnerabilities in the network, but can also collaborate and learn from past disruptions. Concerns were expressed about the level of funding for maintaining and upgrading the region’s transport networks, particularly for territorial authorities with large networks and small rates bases. The region is strongly dependent on the roading network, with limited alternatives during roading network disruptions. It proved difficult to quantify the environmental impacts of transport disruptions. A case study of the response of a local ii health shuttle service provided an example of how a community, by drawing on social capital, was able to adapt and respond appropriately to a transport disruption. One key area identified for further research is assessing the capacity of private contractors to respond to natural hazard events of varying magnitudes. The RIF could also be strengthened by the use of indicators based on quantitative data, in addition to qualitative data. It is suggested that one method of achieving this could this could be to adopt a multi-disciplinary approach, drawing on expertise, methods and perspectives from related professions, such as engineering and economics.

Provenance of Sediment Deposits in Lake Tempe, South Sulawesi

Sedimentation rate in Lake Tempe is a serious problem faced by the government and local communities due to the high sediment transport from upstream of several rivers that flow into Lake Tempe. This study aims to determine the source of the rock material based on analysis of heavy mineral sediment. The research area is located at the estuary of Bila River in Sidenreng Rappang Regency. The method used is test pit and surface sampling. Laboratory analyzes were performed is the analysis of grain size (granulometry), heavy mineral analysis (heavy mineral separation) and microscopic analysis. There are 14 types of heavy minerals found in the Tempe Lake namely: zircon, tourmaline, rutile (ZTR) as ultra stable mineral. The less stable minerals are epidote; and others are olivine, hipersten, augite, hornblende, biotite, casiterit,, brookit, apatite, magnetite and iron oxide. Source rocks of the minerals are interpreted from igneous and volcanic rocks of acidic to intermediate type

Kekhasan Lokal Kurikulum Inti Pendidikan Arsitektur Berbasis Kompetensi

Sistem pendidikan tinggi merupaka nsuatu proses yang memiliki empat tahapan pokok yaitu :masukan, proses, luaran, dan hasilikutan (outcomes). Kurikulum pendidikan bertujuan untuk menghasilkan lulusan yang profesional dan berkualitas serta memiliki ciri utama sebagai implementasi terhadap aspek kekhasan lokal.Pendidikan arsitektur yang diselenggarakan pada perguruan tinggi dapat meliputi jenis dan jenjang penyelenggaraan pendidikan yang bersifat mendasar. Namun pada jenjang pendidikan kearsitekturan, keragaman kurikulum sangat penting untuk diangkat sebagai benang merah pendidikan arsitektur yang berbasis kompetensi sebagai tuntutan global.Di sampingitu, Perubahankurikulum terjadi akibat adanya otonomi perguruan tinggi yang di jamin sesuai Undang-Undang Sistem Pendidikan Nasional, yang member kelonggaran terhadap perguruan tinggi untu kmenentukan dan mengembangkan kurikulumnya.Hal ini juga penting untuk diungkapkan karena menyangkut ciri dan kekhasan lokal serta keunikan wilayah yang dapat diangkat menjadi bagian atau jiwa dari kurikulum inti pada penyelenggaraan pendidikan tinggiberada. &nbsp; Kata Kunci&nbsp;:&nbsp;kekhasan lokal, pendidikan arsitektur, kompetensi, kurikulum inti
