All-temperature superfluidity in two dimensions
Bilal Hawashin, Soumyadeep Chaudhuri, Igor F. Herbut +1
In local theories with short-range interactions, continuous symmetries cannot be spontaneously broken in two spatial dimensions at nonzero temperature. -symmetric mo…
Exploring thermal order in conformal theories with multiple scalars coupled to an vector field
Soumyadeep Chaudhuri, Bilal Hawashin, Eliezer Rabinovici +1
We study thermal order in conformal field theories (CFTs) in and dimensions where several scalars are coupled to an vector field. In dimensions, we con…
Symmetry breaking at high temperatures in large N gauge theories
Soumyadeep Chaudhuri, Eliezer Rabinovici
Considering marginally relevant and relevant deformations of the weakly coupled -dimensional large conformal gauge theories introduced in arXiv:2011.13981, we study the…
Thermal order in large N conformal gauge theories
Soumyadeep Chaudhuri, Changha Choi, Eliezer Rabinovici
In this work we explore the possibility of spontaneous breaking of global symmetries at all nonzero temperatures for conformal field theories (CFTs) in space-time dimension…
Thermal Order in Conformal Theories
Noam Chai, Soumyadeep Chaudhuri, Changha Choi +3
It is widely expected that at sufficiently high temperatures order is always lost, e.g. magnets loose their ferromagnetic properties. We pose the question of whether this is always…
Nonlinear Langevin dynamics via holography
Bidisha Chakrabarty, Joydeep Chakravarty, Soumyadeep Chaudhuri +3
In this work, we consider non-linear corrections to the Langevin effective theory of a heavy quark moving through a strongly coupled CFT plasma. In AdS/CFT, this system can be iden…
Out of time ordered effective dynamics of a quartic oscillator
Bidisha Chakrabarty, Soumyadeep Chaudhuri
We study the dynamics of a quantum Brownian particle weakly coupled to a thermal bath. Working in the Schwinger-Keldysh formalism, we develop an effective action of the particle up…
Out of Time Ordered Quantum Dissipation
Bidisha Chakrabarty, Soumyadeep Chaudhuri, R. Loganayagam
We consider a quantum Brownian particle interacting with two harmonic baths, which is then perturbed by a cubic coupling linking the particle and the baths. This cubic coupling ind…
Spectral Representation of Thermal OTO Correlators
Soumyadeep Chaudhuri, Chandramouli Chowdhury, R. Loganayagam
We study the spectral representation of finite temperature, out of time ordered (OTO) correlators on the multi-time-fold generalised Schwinger-Keldysh contour. We write the contour…
Probing Out-of-Time-Order Correlators
Soumyadeep Chaudhuri, R. Loganayagam
We present a method to probe the Out-of-Time-Order Correlators (OTOCs) of a general system by coupling it to a harmonic oscillator probe. When the system's degrees of freedom are t…
Abelian Tensor Models on the Lattice
Soumyadeep Chaudhuri, Victor I. Giraldo-Rivera, Anosh Joseph +2
We consider a chain of Abelian Klebanov-Tarnopolsky fermionic tensor models coupled through quartic nearest-neighbor interactions. We characterize the gauge-singlet spectrum for sm…
