Glassy states in fermionic systems with strong disorder and interactions
David J. Schwab, Sudip Chakravarty
We study the competition between interactions and disorder in two dimensions. Whereas a noninteracting system is always Anderson localized by disorder in two dimensions, a pure sys…
Diamagnetism of nodal fermions
Amit Ghosal, Pallab Goswami, Sudip Chakravarty
Free nodal fermionic excitations are simple but interesting examples of fermionic quantum criticality in which the dynamic critical exponent , and the quasiparticles are well…
Quantum dynamics of an Ising spin-chain in a random transverse field
Xun Jia, Sudip Chakravarty
We consider an Ising spin-chain in a random transverse magnetic field and compute the zero temperature wave vector and frequency dependent dynamic structure factor numerically by u…
Replacing energy by von Neumann entropy in quantum phase transitions
Angela Kopp, Xun Jia, Sudip Chakravarty
In the thermodynamic limit two distinct states of matter cannot be analytic continuations of each other. Classical phase transitions are characterized by non-analyticities of the f…
Criticality in correlated quantum matter
Angela Kopp, Sudip Chakravarty
At quantum critical points (QCP) \cite{Pfeuty:1971,Young:1975,Hertz:1976,Chakravarty:1989,Millis:1993,Chubukov:1 994,Coleman:2005} there are quantum fluctuations on all length scal…
Broken time-reversal symmetry in strongly correlated ladder structures
U. Schollwoeck, Sudip Chakravarty, J. O. Fjaerestad +2
We provide, for the first time, in a doped strongly correlated system (two-leg ladder), a controlled theoretical demonstration of the existence of a state in which long-range order…
