Beyond aggregation: Pathological phase transitions in neurodegenerative disease
Science, 2020 Over the past decade, phase transitions have emerged as a fundamental mechanism of cellular organization. In parallel, a wealth of evidence has accrued indicating that aberrations in phase transitions are early events in the pathogenesis of several ...

Magnetic field induced orientational transitions in liquid crystals doped with carbon nanotubes
Beilstein Journal of Nanotechnology, 2017 We propose a continuum theory of orientational phase transitions induced by an external magnetic field in a suspension of carbon nanotubes in a nematic liquid crystal.

Entanglement Induced Phase Transitions [PDF]
, 2001 Starting from the canonical ensemble over the space of pure quantum states, we obtain an integral representation for the partition function. This is used to calculate the magnetisation of a system of N spin-1/2 particles.

Ferrocholesteric–ferronematic transitions induced by shear flow and magnetic field
Beilstein Journal of Nanotechnology, 2017 We study the unwinding of the ferrocholesteric helical structure induced by a combined action of a magnetic field and a shear flow. Both influences are able to induce the ferrocholesteric–ferronematic transition independently; however, the differences ...

Topological phase transitions induced by varying topology and boundaries in the toric code
New Journal of Physics, 2021 One of the important characteristics of topological phases of matter is the topology of the underlying manifold on which they are defined. In this paper, we present the sensitivity of such phases of matter to the underlying topology, by studying the ...

Spectral theory of Liouvillians for dissipative phase transitions [PDF]
Physical Review A, 2018 A state of an open quantum system is described by a density matrix, whose dynamics is governed by a Liouvillian superoperator. Within a general framework, we explore fundamental properties of both first-order dissipative phase transitions and second ...

The effect of the lateral interactions on the critical behavior of long straight rigid rods on two-dimensional lattices [PDF]
Papers in Physics, 2009 Using Monte Carlo simulations and finite-size scaling analysis, the critical behavior of attractive rigid rods of length $k$ ($k$-mers) on square lattices at intermediate density has been studied.

Quantum phase transitions of the diluted O(3) rotor model [PDF]
, 2006 We study the phase diagram and the quantum phase transitions of a site-diluted two-dimensional O(3) quantum rotor model by means of large-scale Monte-Carlo simulations. This system has two quantum phase transitions, a generic one for small dilutions, and

Review of cosmic phase transitions: their significance and experimental signatures [PDF]
Reports on progress in physics. Physical Society, 2018 The study of cosmic phase transitions are of central interest in modern cosmology. In the standard model of cosmology the Universe begins in a very hot state, right after at the end of inflation via the process of reheating/preheating, and cools to its ...
