Interface phases and dynamics in two-dimensional quantum magnets: A "holographic" approach from universality to quantum simulation
Abhishodh Prakash, Jaydev Singh Rao, Siddharth A. Parameswaran +1
We introduce a framework to classify quantum phases, phase transitions, and non-equilibrium dynamics of interfaces separating ordered bulk domains in 2D quantum magnets - equivalen…
Classical fractons with cosmological fixed points
Akash Singh, Dileep P. Jatkar, S. L. Sondhi +1
Classical fractons are Hamiltonian systems that can develop attractors after projection onto configuration or shape variables, although the full phase space admits none. We study a…
Continuum Fractons: Quantization and the Few Body Problem
Ylias Sadki, Abhishodh Prakash, S. L. Sondhi
We formulate a continuum quantum mechanics for non-relativistic, dipole-conserving fractons. Imposing symmetries and locality results in novel phenomena absent in ordinary quantum…
Topological Phenomena Protected by Diabolical Textures
Sayantan Mandal, Neelima Pulletikurty, Abhishodh Prakash
We present a new class of topological phenomena in inhomogeneous systems arising from the adiabatic spatial embedding of parametrized families of quantum states such as charge pump…
Textured phase diagrams of featureless insulators
Sashank Singam, Nick G. Jones, Abhishodh Prakash
We study phase diagrams of charge-conserving `class A' non-interacting fermions, focusing on the trivial phase in various dimensions. Such phases are usually termed `featureless' t…
Phase space fractons
Ylias Sadki, Abhishodh Prakash, S. L. Sondhi +1
Perhaps the simplest approach to constructing models with sub-dimensional particles or fractons is to require the conservation of dipole or higher multipole moments. We generalize…
