  • Multi-Grand, Multi-Canonical, Flat Histogram, Monte Carlo Simulations for the Square Well Fluid

    Creator:
    Trotter, Cade W.
    Abstract:
    Currently multi-canonical, and grand canonical Monte Carlo simulations exist, but do not always give all of the necessary information of the system. When using a 1-D (only changing in one variable) broad histogram Monte Carlo method a user would need to run a range of simulations in order to get...

  • Simulating Fluids: Testing a New Grand Canonical Histogram Method on the Square-Well Fluid

    Creator:
    Vande Griend, Jacob W.
    Abstract:
    Monte Carlo methods are used to explore vapor-liquid phase transitions. However, current models are computationally expensive when identifying these phase transitions. Traditionally, Monte Carlo simulations are run across a range of temperatures at a fixed number of atoms/molecules. The Number Monte Carlo method (NMC), our proposed Monte Carlo method, runs...

  • Simulating dynein’s powerstroke using Brownian dynamics

    Creator:
    Capek, Elliott L.
    Abstract:
    Dynein is a motor protein which transports cargo along tracks inside the cell. Like related motor proteins kinesin and myosin, dynein uses cellular energy to take steps with its two foot domains. Unlike kinesin or myosin, dynein’s stepping pattern is highly varied: it can take steps between zero and 60nm...

  • Calculating characteristic timescales for environmental decoherence in the presence of thermal gravitons

    Creator:
    Nelson, Hunter
    Abstract:
    Different models show the effects of environmental decoherence on a quantum system due to various environments of interest. One important quantity within these models is the decoherence time, which tells us how quickly environments wash away the coherence of local measurements. We can describe this effect as the quantum system...

  • A Generalized Scheme for Creating Regge Calculus Models of General Relativity

    Creator:
    Hanson, Ben R.
    Abstract:
    Solutions to Einstein's equations are usually found by considering ideal, simplified models. However, if the real world always matched ideal physics models, then farmers would milk black and white spheres. To combat this, Regge calculus was developed as a numerical approximation scheme for general relativity. In Regge calculus curved manifolds...

  • Monte Carlo Simulations for a Soft Sphere Fluid

    Creator:
    Kreitzberg, Patrick
    Abstract:
    In this paper I present the results of Monte Carlo simulations for a soft sphere fluid with a Weeks-Chandler-Anderson (WCA) pair potential. The results are compared to Soft Fundamental Measure Theory (SFMT) results obtained by our research group. One of the research group’s goals was to show that our SFMT...

  • The Consistent Histories Approach to the Stern-Gerlach Experiment

    Creator:
    Wilson, Ian
    Abstract:
    Standard quantum mechanics makes foundational assumptions to describe the measurement process. Upon interaction with a “classical measurement apparatus”, a quantum system is subjected to postulated “state collapse” dynamics. We show that framing measurement around state collapse and ill-defined classical observers leads to interpretational issues, and artificially limits the scope of...

  • Min protein oscillations in E. Coli

    Creator:
    Zeto, Rene
    Abstract:
    The Min protein system in Escherichia coli helps the cell division process by identifying the center of the cell [1, 7]. This system has been modeled succesfully computationally under standard conditions. There has been recent experimental interest in the cell division process for significantly perturbed cell shapes. We take the...

  • Drunken Walking: A Novel Brownian Dynamics Simulation for the Mechanochemical Cycle of the Dynein Motor Protein

    Creator:
    Waczak, John L.
    Abstract:
    The dynein molecule is a peculiar motor protein recognized for its unique stepping behavior. Sometimes it steps forwards. Other times it steps backwards. It has even been observed to occasionally shuffle by beginning a step with the same domain many times in row. These motions make dynein an interesting object...
